When you look at your heating bills you realize just how expensive this long winter has been. If it has you thinking about replacing your existing heating system before next winter, here are the average energy costs of the four most common heating fuels based on usage in the northeastern part U.S. Heating with oil is the most expensive, at an average of $2,560 for the winter. Propane has become a popular fuel choice but it ranks the third at $2,380. Electricity has seen some growth in popularity with an average winter heating cost of $1,315. Natural gas is the least costly, with the average cost at $1,025. Of course costs depend how warm you keep your house, how well your home is insulated, and other individual factors. But if you want a new heating system before next winter we can recommend the most energy-efficient choice for your home. Call us at 610-593-5129 for a free consultation. - [Get Ducts Cleaned before Spring Pollen Season](https://sumzim.com/get-ducts-cleaned-before-spring-pollen-season/): Did you know that just .04 of an inch of dust on your heating coil can reduce the efficiency of your HVAC system by 21%? And, if that amount of dust builds up on your fan the loss of efficiency is almost 50%. Heating systems have been working harder than ever this past winter, which makes it even more important to get them checked and have new, clean filters put in now. Spring starts today and it’s easy to think you can ignore your heating system since you won’t need it much longer. But it’s best to have this done before the weather is warm enough to shut off your heating system so that your ducts are clean and dust-free before the heavy pollen season starts. Call us at 610-593-5129 and we’ll schedule a technician right away. - [Are You Prepared for a Plumbing Emergency?](https://sumzim.com/are-you-prepared-for-a-plumbing-emergency/): When an appliance failure causes a toilet, washing machine, or dishwasher to overflow, are you ready for a plumbing emergency? It’s important to get the water flow stopped immediately then clean any water on the floor before it causes major damage. Here are a few tips. - [How to Avoid Water Damage to Your Home](https://sumzim.com/how-to-avoid-water-damage-to-your-home/): The good news is that the snow is melting and we’re seeing some 50-degree temperatures! But when rain comes with the snowmelt, be sure all the water has some place to go instead of inside your home. Puddles of water around your foundation can seep through walls into basements and garages. To avoid water damage to your home, be sure your spouting is clear of clogs and any ice or debris that may have gotten trapped inside them during the cold winter. Be sure the drain ends of the spouting are cleared so the water can flow out and that there is no snow or mud is blocking the water flow away from the house. - [Time to Check Your Sump Pump](https://sumzim.com/time-to-check-your-sump-pump/): When temperatures get above freezing and the snow melts, there will be a lot of moisture in the ground. If we have a rainy spring along with the snow melt, there are sure to be a lot of wet basements. To avoid having a flooded basement this spring be sure your sump pump is in good working order. To test your sum pump lift the float inside until it causes the pump to come on and add water to the area where your pump is located. This should cause the pump to come on. Don't cause the pump to come on by lifting the float without adding water, as that could damage it. If your test shows that your pump isn't working call us at 610-593-5129 to have one of our plumbing technicians do the appropriate repairs. - [A Service Contract Reminder](https://sumzim.com/a-service-contract-reminder/): The saying "an ounce of prevention is worth a pound of cure" is right on target when it comes to having a service contract for your plumbing and HVAC. At Summers & Zim’s a service contract means that all your equipment gets checked and routine maintenance is done so you don’t have to worry about breakdowns. But the most important part of a service contract is that when you have an emergency, you go to the top of the list for service. With the severe winter we've just experienced, our technicians were busy 100% of the time taking care of service contract customers. We simply were not able to get to the non-service contract requests quickly because demand was so high. Now is the time to make sure you are always a priority. If you don't have a service contract, call us at 610-593-5129 and we'll set one up. Spring will be here soon and it's a good time to get a post-winter, pre-summer service done to be sure all your equipment is in great condition. And, it gets you at the top of the list for any weather emergencies. - [Check Downspouts, Gutters, and Drains to Avoid Water Backup and Damage](https://sumzim.com/check-downspouts-gutters-and-drains-to-avoid-water-backup-and-damage/): With the heavy amounts of snow this winter, we already know we're in for a soggy spring. As all the snow melts the ground gets over-saturated. Water from melting snow on the roof will run through downspouts and can pool along the foundation of your home where it can seep into your walls and cause mildew, molds, and structural damage. Take advantage of the first nice day to do a visual check to see if water is running out the downspouts and away from the house as it should. If gutters along rooflines and porches have water overflowing out of them, and if water isn’t draining properly from downspouts, they are most likely clogged. It's essential to get rid of the clogs and direct the water away from your home. - [After a Long, Cold Winter, An Air Scrubber May be Essential](https://sumzim.com/after-a-long-cold-winter-an-air-scrubber-may-be-essential/): For months your home has had no fresh air. Sub zero temperatures and heavy snowfalls have had us all keeping windows and doors tightly closed. During that time odors from cooking, dander from pets, and everyday dust and dirt have all been affecting the quality of your indoor air. It may be many more weeks before outdoor temperatures are high enough to allow fresh air inside. That's why now is a great time to add an Air Scrubber to your home. An Air Scrubber can be essential to improve your daily quality of life. Air Scrubbers remove particles, gases, and chemicals from the air to purify it. They can be installed individually or as part of a heating/cooling system. Talk to a technician at Summers & Zim’s about what model Air Scrubber is best for your home. Call us at 610-593-5129 to get one installed soon, before spring pollen adds even more pollution to the air. - [Safety Tips for Propane Tanks During Heavy Snow](https://sumzim.com/safety-tips-for-propane-tanks-during-heavy-snow/): If you have a propane tank, be sure you don’t damage it when clearing heavy snow. Do not push snow off the roof onto the propane tank. The weight of the snow can damage the pipes and fittings, causing gas leaks. When cleaning snow off the tank use a broom or brush instead of a shovel. Check the regulator vents on your propane system to be sure they are free of snow, ice, or water that could freeze. If a heavy snow is forecast, cover the regulator, relief valves, and fill valves with a protective dome cover that will keep out the snow ice and moisture but won’t block the valves. Prior to the storm mark the location of the tank with snow stakes that extend well above the anticipated snow depth. If your propane heat goes out during a snow storm call us at 610-593-5129. - [How to Combat Higher Prices and Colder Temps](https://sumzim.com/how-to-combat-higher-prices-and-colder-temps/): Consumers are being hit with a double whammy this winter. Prices for natural gas are up as much as 13% and electricity is up about 2%. Heating fuel is about the same, but is still one of the most expensive fuels. As these prices increase, so has fuel consumption due to a colder than average winter. One way to conserve on fuel costs is by changing the way you dress. By choosing clothing made in warmth retention fabrics such as fleece, Polartec™, cashmere, and wool you can lower your thermostat and still stay warm. Also lower your thermostat when you sleep and put an extra blanket on your bed. If there is no one home during the day, lowering the temperature will add even more savings. Lowering your thermostat just one degree will save about 10% on your heating bill. - [Unplug to Save Energy](https://sumzim.com/unplug-to-save-energy/): How many devices do you have plugged in at your home right now? The average household keeps 40 or more appliances, lamps and electronic devices plugged in all the time. Each of these is using electricity, even if they are turned off. In severe winters, such as the one we’re experiencing this year, if each of us would unplug items not in use it will give a huge boost to the energy grid. Obviously there are many items you need to keep plugged in, but here are some that can be plugged only as you need them: Toasters, coffee makers, stereos/radios, lamps, night lights, electric toothbrushes, blow dryers, curling irons, plug in room fresheners/scents, and camera chargers. Experts say that up to 30% savings can be seen from staying unplugged for non-essential items. - [How to Prepare for a Winter Power Failure](https://sumzim.com/how-to-prepare-for-a-winter-power-failure/): Power supply interruptions can happen in winter due to high winds, freezing rain, or sleet that brings down power lines. Most disruptions are usually fixed within hours. To remain comfortable in your home during a failure make these preparations. Have warm clothing you can layer, and a supply of blankets. If you have a gas fireplace, check if it has a battery feature that lets you start it without using the switch. This can give you a heat source in at least one room. If you have a wood burning fireplace, keep a supply of dry seasoned wood. Be sure the fireplace was cleaned of creosote prior to the cold weather. Unplug appliances, lamps, computers, TVs and tools that were running when the outage happened. Leave just one night light plugged in so you know when power is restored. Have emergency lamps that use battery powered LED lights. They will provide light for a long time and are much safer than candles. Keep a supply of batteries on hand. Have foods that don't need cooked and a supply of bottled water. Have a battery powered radio so you can get news and updates from broadcast sources. Leave one faucet on with a slow drip to keep pipes from freezing. Use mobile phones or devices only for emergency calls so you don't delete the batteries. Your home should stay reasonably warm for up to 4-5 hours after a power failure in winter. If a failure becomes extended, you may need to go to an emergency shelter in a local school, church, or community center. - [How Your Service Contract Helps Others](https://sumzim.com/how-your-service-contract-helps-others/): The extended cold has caused a huge demand for emergency heating repairs and heating system replacements. Our techs are working night and day to take care of customers. It occurred to us that we should take time to thank those customers who didn't have emergency heating repair needs this winter. The customers who had their heating systems serviced and maintained under their service contracts before the cold weather got here, haven't needed to call us. And that means we can get to more emergency calls for others who gambled that their systems would be OK through the winter. Customers who recognize the value of preventive maintenance keep their systems well maintained so there are no unpleasant surprises from frozen pipes or days without heat. We want to thank you for being a service contract customer. Your foresight makes it possible for us to help more people who have emergency needs. ## Pages - [Plumber in Coatesville, PA](https://sumzim.com/plumber-in-coatesville-pa/): Whether you're dealing with a leaking pipe, a clogged drain, low water pressure, or a failing water heater, having access to a reliable plumber can help keep your home comfortable and functioning properly.

Frequent breaker trips, flickering lights, buzzing sounds, or difficulty running multiple appliances at the same time can all point to an overloaded system. Many older homes were built before modern electrical demands increased with devices, home offices, smart technology, and electric vehicles. If you're planning a renovation or adding major equipment, an electrical panel evaluation can help determine whether an upgrade would improve safety, reliability, and overall performance.Can I install an electric vehicle charger at home?Yes. Many homeowners choose to install a dedicated EV charging station to make charging more convenient and efficient. While standard outlets can provide a charge, most electric vehicle owners prefer a Level 2 charger because it significantly reduces charging time. Before installation, an electrician should evaluate your electrical system to confirm it can support the additional demand. In some cases, a panel upgrade or dedicated circuit may be recommended to help the charger operate safely and efficiently. Is a whole-home generator worth installing?A whole-home generator can provide valuable peace of mind during power outages, especially during severe weather events. Unlike portable generators, whole-home systems automatically restore power to selected circuits or the entire home when utility service is interrupted. Homeowners often use generators to keep heating and cooling systems running, protect refrigerated food, power medical equipment, and maintain internet access. The right system depends on your home's electrical needs, budget, and the level of backup power you would like during an outage. What happens during an electrical safety inspection?An electrical safety inspection is designed to evaluate the condition and performance of your home's electrical system. During the inspection, an electrician may examine the electrical panel, wiring, outlets, switches, grounding systems, smoke detectors, and other key components. The goal is to identify potential hazards, outdated equipment, code concerns, or areas where upgrades may be beneficial. Safety inspections are often recommended for older homes, homes being purchased or sold, and homeowners who have noticed recurring electrical issues. Can smart home technology be added to an existing home?Yes. Smart home technology can often be integrated into existing homes without extensive remodeling. Many homeowners start with smart thermostats, lighting controls, video doorbells, security systems, or automated switches and expand their systems over time. Smart technology can provide greater convenience, energy management, and control over household systems through mobile devices or voice commands. An electrician can help determine which products are compatible with your home's electrical system and recommend options that align with your goals and lifestyle. When should I call an electrician for electrical repairs?It's important to contact an electrician whenever you notice signs that something may not be functioning properly. Common warning signs include flickering lights, warm outlets, burning odors, sparking outlets, buzzing sounds, or breakers that repeatedly trip. While some issues may appear minor at first, electrical problems can become more serious if left unaddressed. A professional inspection can identify the source of the problem, explain your repair options, and help restore safe and reliable operation throughout your home.  - [Application Confirmation](https://sumzim.com/application-confirmation/): One of our managers will review your application and will reach out if a position opens up. - [Contact Joe Confirmation](https://sumzim.com/contact-joe-confirmation/): I'll read your message shortly and look forward to connecting with you. - [Membership Request Confirmation](https://sumzim.com/membership-request-confirmation/): It is important to us that we are able to respond to an emergency need right away.

If your system is more than 10 to 15 years old, requires frequent service calls, struggles to maintain consistent temperatures, or causes unusually high energy bills, replacement may be worth considering. While repairs can often extend the life of a system, there comes a point when ongoing repair costs begin to outweigh the benefits. A professional evaluation can help you compare your options and make the decision that best fits your home and budget.How long does a typical heating and cooling system last?The lifespan of an HVAC system depends on factors such as equipment type, maintenance history, usage patterns, and installation quality. Many air conditioners and heat pumps last between 10 and 15 years, while some furnaces can operate effectively for 15 to 20 years. Regular maintenance can help extend system life, but all equipment eventually experiences wear and reduced efficiency. As systems age, replacement often becomes a more cost-effective long-term option than continuing to invest in major repairs. Will a new HVAC system lower my energy bills?Many homeowners notice improved energy efficiency after replacing older equipment. Modern systems are designed to use less energy while providing more consistent comfort throughout the home. New technology, improved system design, and higher efficiency ratings can help reduce energy consumption compared to aging equipment. While actual savings vary depending on the home and system selected, many homeowners choose replacement specifically because their existing equipment is becoming less efficient over time.How do I choose the right replacement system for my home?The best replacement system depends on several factors, including your home's size, insulation, comfort preferences, budget, and existing equipment. Bigger is not always better when it comes to HVAC equipment. Proper sizing is essential for efficiency, comfort, and system performance. During the replacement process, a professional evaluation can help determine which equipment options are most appropriate for your home's specific heating and cooling needs.What happens during an HVAC system replacement?The replacement process typically begins with an assessment of your current equipment and comfort needs. Once a system is selected, technicians remove the existing equipment and install the new components according to manufacturer specifications. Depending on the project, additional updates may include thermostats, ductwork modifications, or electrical connections. Most residential system replacements can be completed within a day, although larger or more complex installations may require additional time.Are heat pumps a good replacement option in Southeastern Pennsylvania?Heat pumps have become an increasingly popular option for homeowners looking to improve efficiency and reduce energy consumption. Modern heat pump systems can provide both heating and cooling from a single system and perform effectively in a wide range of weather conditions. Depending on your home's needs and existing equipment, a heat pump may be an option worth considering during the replacement process. A professional consultation can help determine whether a heat pump is the right fit for your comfort goals and budget.  - [Scary Stories with Alli](https://sumzim.com/scary-stories-with-alli/) - [Design Your Blue Membership](https://sumzim.com/design-your-customer-membership/) - [Contact Confirmation](https://sumzim.com/contact-confirmation/): We look forward to taking care of you and will be in touch soon. - [Blog](https://sumzim.com/about-us/blog/) - [Transparency in Coverage](https://sumzim.com/transparency-in-coverage/): The Transparency in Coverage Final Rules require group health plans and health insurance issuers to disclose on a public website detailed pricing information in machine-readable files (MRFs).

If the problem persists, call us for emergency services. Fast, reliable help is on the way! How often should I schedule furnace maintenance? At least once per year—ideally in the fall—before winter demand hits. Inspections ensure safe and efficient performance when you need it most. Why does my furnace blow cold air sometimes? This problem could mean a dirty filter, pilot light issue, or overheating. A winter tune-up can catch these problems early. Is it normal for my furnace to smell when it first turns on? A brief dusty smell is common if the system hasn’t run in a while. However, a burning or gas odor is a sign to call for service immediately. Should I repair or replace my old furnace before winter? If your unit is over 15 years old or frequently needs repairs, replacement may be the safer and more cost-effective option for the season.  - [Heat Pump Maintenance, Repair, & Replacement in Chester County, PA](https://sumzim.com/services/heating/heat-pump-repair-and-replacement/): Winter Heat Pump FAQs  Do heat pumps work in freezing temperatures? Yes, heat pumps can still function in freezing weather. However, they may switch to auxiliary heat to keep up with demand, especially below 30°F. What is auxiliary heat, and why is it running? Auxiliary heat is a backup heating method—often electric or gas—that kicks in when your heat pump alone can’t maintain your desired temperature. It’s common in winter but may signal inefficiency if used too often. Should I service my heat pump before winter? Absolutely. Pre-winter servicing ensures your unit runs efficiently and reliably and helps prevent unexpected cold-weather breakdowns. What are signs my heat pump needs repair in winter? Cold spots, higher energy bills, unusual noises, frequent auxiliary heat usage, or your home feeling chilly despite running the system are all signs it may need attention.Is a dual-fuel system worth it? Yes! A dual-fuel system switches between a heat pump and a gas furnace based on the outdoor temperature for the most cost-effective and efficient heating.  - [Common Problems With Home Heating Furnaces](https://sumzim.com/services/heating/furnaces-common-problems/) - [Boiler Maintenance, Repair, and Replacement in Central PA](https://sumzim.com/services/heating/boiler-repair-replacement/): FAQs About Winter Boiler Services  How often should I schedule boiler maintenance? Ideally, once a year—preferably in the fall—to ensure your system is ready before winter hits. Why is bleeding radiators before winter important? Air pockets block hot water flow, reducing efficiency and causing cold spots. Bleeding radiators restores proper heat distribution. Can frozen pipes damage my boiler? Yes. Frozen pipes can cause pressure imbalances, leaks, or even boiler shutdowns. Prevent freeze-ups with proper insulation and thermostat settings. What’s the best way to improve boiler efficiency in winter? Schedule professional maintenance, monitor pressure regularly, and consider upgrading to a gas system if you currently use oil. What temperature should I set my thermostat to in cold weather? Aim for around 68–70°F during the day and lower it slightly at night. Avoid drastic drops to prevent pipe freezing. When should I consider boiler replacement? A replacement may be more cost-effective if your boiler is over 15 years old, needs frequent repairs, or isn’t heating your home evenly.  - [Well Pump Maintenance, Repair, & Replacement in Central PA](https://sumzim.com/services/plumbing/well-pump-repair-replacement/) - [Water Treatment Services in Chester County, PA](https://sumzim.com/services/plumbing/water-treatment/) - [Water Softener System Installation in Central PA](https://sumzim.com/services/plumbing/water-softener-system-installation/) - [Water Heater Maintenance, Repair, & Replacement in Chester County, PA](https://sumzim.com/services/plumbing/water-heater-repair-replacement/) - [Sump Pump Repair, Replacement, & Installation in Central, PA](https://sumzim.com/services/plumbing/sump-pump-repair-replacement/) - [Sewage System Maintenance, Repair, & Replacement in Chester County, PA](https://sumzim.com/services/plumbing/sewage-system-repair-replacement/) - [Reverse Osmosis Water System Installation in Central PA](https://sumzim.com/services/plumbing/reverse-osmosis-water-system-installation/) - [Repairing Clogged Drains and Drain Cleaning in Central PA](https://sumzim.com/services/plumbing/clogged-drains-and-drain-cleaning/) - [Plumbing Leak Repair in Central PA](https://sumzim.com/services/plumbing/leak-repair/) - [Plumbing FAQs](https://sumzim.com/services/plumbing/plumbing-faqs/): No one wants to see their bathroom plumbing go down the drain, but it happens.
