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

Warning Signs Your Furnace Needs Attention

Furnace problems rarely fix themselves, and catching the warning signs early can save you from a bigger repair down the road. Here are some signals that it’s time to call for service.

Furnace Problems Our Technicians Repair Most

Furnaces in our region work hard through long Pennsylvania winters, and that constant use leads to a handful of issues we see time and again. Ignition and pilot control failures are among the most common calls we get, often leaving homeowners with a furnace that won’t start at all. Faulty thermostats and wiring issues can also cause furnaces to run inconsistently or fail to respond properly to temperature changes.

Blower motor failures and clogged filters are another frequent source of trouble, both of which restrict airflow and force the system to work harder than it should. We also regularly repair cracked heat exchangers, which can be a safety concern if left unaddressed, as well as worn-out belts, faulty limit switches, and issues with the ductwork itself. Our technicians carry the tools and parts needed to handle most repairs during the first visit.

Professional Furnace Repair Solutions

Every furnace repair call starts with a full diagnostic to find the root cause of the problem, not just a quick patch that leaves you calling again next month. Our technicians walk you through what they find and explain your repair options in plain language, so you always know what’s going on with your system before any work begins.

Once we’ve identified the issue, we complete repairs efficiently using quality parts built to last. We service all furnace makes and models, so whether you have a newer high-efficiency unit or an older system that needs a little extra care, our team has the experience to handle it. We also stand behind every repair with the same commitment to honest, fair pricing that has defined our business for three generations.

West Middlesex winters bring a mix of damp, cold, and fluctuating humidity that puts extra strain on furnace components, particularly heat exchangers and ignition systems. That combination of moisture and cold can accelerate wear on parts that aren’t properly maintained. Our familiarity with the local climate helps us anticipate the issues homeowners in this area are most likely to face each season.
