The Summers & Zim's Difference

We Are Good Natured

We genuinely enjoy coming to work every day. Not all days are easy, but we really do enjoy the people we work with and taking care of the customers we work for. Our customers are an integral part of what makes our jobs exciting.
We Aren't Going Anywhere

Summers & Zim’s has been serving Chester County and Lancaster County since the 1930’s – that’s four generations! We were there for your grandparents when they needed us and plan to serve your grandchildren as well.
We Are the Right Size

Summers & Zim’s is small enough that we can get to know you by name. Our office is small and compact so everyone working here eventually gets to know our customers on a personal level.

Yet, we are large enough to meet your needs. With 25 technicians on staff and a warehouse stocked with parts, in most cases we can fix just about anything the same day.
We Are Safe

Each and every Summers & Zim’s employee is tediously drug tested and background checked. Our technicians are people we trust with our families in our very own homes.
We Are Normal People

Sometimes, we make mistakes. And when we do, we own up to them. We have a list of satisfaction guarantees on the back of every service ticket. Our reputation matters way more to us than our revenue. When we mess up, we genuinely want to make things right.

Discover Our 5-Point Guarantee

What do we mean when we talk about “service excellence”? Our definition of service excellence is summed up in our 5-Point Guarantee, which includes promises about:

1. Design Guarantee

When we make a recommendation on what types of systems will work best in your home, we stand behind those recommendations. If something proves to not be the right fit, or if it isn’t working properly, we’ll make it right.
2. No Lemons Guarantee

You should reasonably expect years of performance out of a boiler, air conditioner and other major home appliances you invest in. If we install something that gives out well before its reasonable lifespan, we make it right by installing a full replacement.
3. No Frustration Guarantee

Breakdowns in your home’s appliances can be incredibly frustrating. For example, when a water heater goes out and you’re left to take cold showers in January, that can be frustrating — if not infuriating. When we install a hot water heater or similar appliance and it leaves you frustrated within the first two years, we’ll make it right — and pay you $500 for the inconvenience.
4. Home Protection Guarantee

Anything we damage while working in your home we either repair or replace. This includes carpeting, hardwood and tile flooring, walls, door frames, furniture and more.
5. Performance Guarantee

We always offer a 100 percent money back guarantee. When we install equipment in your home and it does not meet your expectations, we will remove that equipment and pay you back every dime you spent on it.
