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

Warning Signs Your AC Needs Attention

Most air conditioning problems give warning signs before they lead to a full breakdown. Catching these signs early can save you money and keep your home comfortable.

Weak or reduced airflow
Warm air blowing from vents
Strange grinding or squealing noises
Frequent cycling on and off
Higher than normal energy bills
Water is pooling near the unit
Musty or burning odors
Thermostat not responding correctly

What's Causing Your Air Conditioner to Malfunction

Air conditioning issues can stem from a wide range of mechanical and environmental factors. A refrigerant leak is one of the most common culprits, often leading to reduced cooling power and ice buildup on the coils. Electrical components like capacitors and contactors can also wear out over time, especially with heavy summer usage, causing the system to fail to start or shut off unexpectedly.

Dirty or clogged air filters restrict airflow, forcing your system to work harder than it should and leading to overheating and premature wear. Clogged condensate drains are another common issue, often leading to water damage or system shutdowns triggered by safety switches.

Weather in West Middlesex plays a role, too. Summer humidity levels in this part of Pennsylvania put extra strain on cooling systems, since your AC has to work harder to remove moisture from the air in addition to lowering the temperature. Homes that don’t have properly sized or well-maintained systems tend to see more breakdowns during these humid stretches, especially in units that are already older or have been neglected.

How We Handle Every AC Repair

When you call D & G Mechanical for an AC repair, our technicians start with a full inspection of your system to identify the root cause of the problem rather than just addressing the symptoms. We check refrigerant levels, electrical connections, airflow, and all major components to get a clear picture of what your unit needs.

Once we know what’s wrong, we walk you through our findings and provide an honest recommendation before any work begins. We carry a wide range of parts for various makes and models, which allows us to complete most repairs in a single visit. Our goal is always to get your system back up and running as quickly and efficiently as possible without cutting corners.

After the repair is complete, we test the system thoroughly to confirm it’s cooling properly and running efficiently. We also take the time to answer any questions you have and offer tips on maintaining your system going forward.
