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.

Signs Your Furnace Needs Professional Attention

Furnace trouble doesn’t always announce itself loudly. Watch for a few warning signs before a small issue becomes a no heat emergency.

  • Short cycling on and off
  • Thermostat not matching room temperature
  • Loud clicking during startup
  • Vents blowing weak or warm air
  • Higher than normal utility bills
  • Furnace running constantly without shutting off
  • Discolored or sooty flame

Any one of these on its own might not seem urgent, but together they usually point to a system that needs a closer look.

Common Furnace Issues in Hermitage Homes

Hermitage grew rapidly in the decades following its consolidation, and a large share of the housing stock dates to that mid century building boom. Many of these homes were constructed with ductwork sized for smaller, less efficient furnaces than what’s typically installed today, and that mismatch often shows up as rooms that heat unevenly no matter how the system is adjusted.

The city’s flat, open terrain also plays a bigger role than most homeowners realize. With fewer natural windbreaks than the surrounding hills, homes in Hermitage tend to see stronger, more consistent wind exposure during winter storms, which can pull heat out of a house faster and push furnaces to run longer cycles than they would in more sheltered areas. That extra strain tends to wear down ignition systems and blower components ahead of schedule.

Homes closer to the commercial district and newer subdivisions face a different set of issues, often tied to systems that were installed as builder grade equipment and have since aged past their expected lifespan. In these cases, we frequently find that the furnace itself is fine, but sensors, filters, or ductwork connections have started to fail from years of steady, unattended use.

Our Approach to Furnace Repair

We start by listening. Before any tools come out, our technician asks about what’s been happening with the system and when the issue started, since that context often narrows down the likely cause before the inspection even begins.

From there, we check the components most likely to be involved, including the ignition system, blower motor, heat exchanger, and airflow throughout the ductwork. Most furnace problems stem from one of these areas, and identifying the right one early keeps the repair focused instead of turning into guesswork.

Once the issue is confirmed, we explain what we found and what it will take to fix it before doing any work. Repairs are typically finished the same day, and we run the system through a full cycle afterward to confirm it’s heating evenly and holding steady before we consider the job complete.

Inside a Typical Service Visit

Tom reached out on a February afternoon after noticing his furnace near Buhl Park kept shutting off within minutes of starting up. He’d reset the breaker a couple of times hoping it would resolve itself, but the pattern kept repeating and the house was starting to feel the difference.

Our technician found a failing flame sensor that was misreading the burner and triggering a safety shutdown, a common issue in furnaces that have been running steadily for eight to ten years. Once the part was replaced, the system started right up and ran a full cycle without interruption. Tom mentioned he’d been dreading a bigger repair, and was relieved to learn it was a quick, contained fix.
