Heat Pump Installation & Replacement in West Middlesex, PA

D & G Mechanical has helped homeowners throughout West Middlesex, PA, and nearby communities like Cranberry Twp., Wexford, Sewickley, Mars, Treesdale, and Butler stay comfortable for three generations. Our team installs and replaces heat pumps for homes of all sizes, matching each system to the property’s specific needs. Whether you are upgrading an aging unit or installing a heat pump for the first time, we handle the job with the same honest, family-oriented approach we have used since 1985.

Western Pennsylvania winters bring cold temperatures and damp conditions that put extra strain on heating equipment, while humid summers put a lot of strain on your cooling system. A properly sized and installed heat pump can handle both jobs efficiently year-round, but only if it is properly sized and installed for our local climate. Our technicians understand how the weather patterns in West Middlesex affect equipment performance, and we install every system with that in mind.

What Your Neighbors Are Saying About Us

D&G has been my go to company since purchasing our home in 2021! They are always pleasant, dependable, and have been able to get us an appointment within a day or 2! They've been out every year to fix our 35 year old system, but we finally gave in and had it replaced. They were able to fit us in 4 days after signing the contract, and the workers were very efficient, pleasant, and knowledgeable!

Wow, I can’t say enough about D&G Mechanical. Last year I was in need of replacing my A/C unit. I contacted them and the sales representative came out to quote the replacement. He listened to what I had to say then quoted the unit. The price was so good I upgraded the heating unit as well. Then the installation team came for the install. These guys worked as a team.

In the middle of summer our AC went out completely . D&G not only responded quickly with the best estimate quote, we also replaced and updated our furnace as well. They ordered everything, scheduled our installation and expected to wait but a rew days only because they had a cancelation on a stalled construction and showed up the next morning and by the afternoon we had AC again.

D&G Mechanical has been our HVAC maintenance and repair contractor for decades. Prior to the summer season, we decided to replace and upgrade both our air conditioner, furnace and air filtering. Naturally we got quotes for this upgrade. As we anticipated, D&G came through with the best price for the type of air conditioner, heating and air filtering system we desired.

Our heat pump, air and furnace quit unexpectantly in July 2026. D&G came right out, gave us an estimate. They came out and removed the old and replaced everything with a new one. They clean up after themselves, explain everything, are very professional and polite and very reasonable. We only use D&G as no one else compares.

Showed up on time of meeting for estimate. All employees were very professional, knowledgeable and did great work. Definitely would keep this company as my go to for all HVAC maintenance and install. Thanks for the great work

Our Heat Pump Installation & Replacement Process

Every installation begins with a full evaluation of your home, including square footage, insulation, ductwork, and current energy usage. This allows our technicians to recommend a heat pump that is properly sized for your space rather than a one-size-fits-all solution. Correct sizing matters, especially in our region, where humidity levels and seasonal swings can quickly overwhelm a poorly matched system.

Once we determine the right unit for your home, we provide a free estimate that outlines equipment options, costs, and expected timelines. Our sheet metal background, backed by our Local 33 Sheet Metal Workers membership, allows us to fabricate custom ductwork on site when needed rather than relying on generic parts. This means fewer delays and a system built to fit your home rather than the other way around.

On installation day, our technicians remove the old equipment and install the new heat pump, ensuring proper refrigerant charge, electrical connections, and airflow balance. We test the full system before we consider the job complete, checking heating and cooling performance to ensure everything runs as it should. Our goal is always to complete projects promptly without cutting corners.

Why Homeowners Choose Heat Pumps

Heat pumps offer year-round comfort from a single system, which appeals to many homeowners looking to simplify their home’s heating and cooling. Rather than running separate furnace and air conditioning equipment, a heat pump shifts between heating and cooling modes depending on the season, often reducing overall energy use.

In West Middlesex, where summers bring notable humidity and winters bring damp cold, a heat pump can help manage indoor moisture levels more effectively than some traditional systems. This can lead to a more comfortable home environment and less strain on other HVAC components. Many homeowners also find that heat pumps provide quieter operation and steadier temperatures throughout the house.

Because heat pumps use electricity to move heat rather than generate it through combustion, they can also be a more efficient option depending on your home’s setup and local energy costs. Our technicians can walk you through what to expect for your specific home during your free estimate.
