What Your Neighbors Are Saying About Us

We have had a great experience with them for both AC service and our boiler. The service team is professional, knowledgeable, and kind. They also make a big effort to get your job taken care of as soon as possible.

Tom, Julian, and Collin did a fantastic job replacing my oil furnace with a natural gas one. This was a very involved oil to gas conversion and they did a fantastic job running the gas lines and installing the new water heater. They were very courteous and did a great job explaining everything. Fair pricing, I would highly recommend!

I've had to call Davis on several occasions with furnace issues. Each time it was fast responses pleasant & friendly technicians they were very informative & got my heater up & running fast. 5 stars from me.

Extremely happy with our experience. We scheduled a tune up thereafter and the technician Nick H professionally maintained our systems, gave us valuable recommendations, and personally rerouted some HVAC piping to help provide additional head clearance in our tight mechanical room without asking. Highly recommend all around.

Furnace was clicking but not igniting. Called Davis and they said they were backed up but would try to get to me. Half hour later they called and said a technician was on their way. Nick arrived and quickly diagnosed the problem. Am up and warming up! Great service! Would highly recommend

Common Reasons Heat Pumps Break Down

Because a heat pump works year-round, it tends to accumulate wear differently than equipment that only runs part of the year. Refrigerant leaks are one of the most frequent issues we see, often showing up as reduced heating or cooling performance and ice forming on the outdoor unit. Norristown’s humid summers and damp winters both contribute to this wear, since the system is constantly cycling refrigerant to manage temperature in both directions.

A malfunctioning reversing valve is another common problem, and it’s particularly common in heat pumps, since it is the component responsible for switching between heating and cooling modes. When it fails, a system may get stuck blowing cold air even when set to heat, or vice versa. We also frequently address issues with the defrost cycle, which is especially important during Norristown’s cold winter months, since a heat pump that can’t properly defrost its outdoor coil will struggle to heat a home efficiently. Electrical issues, worn capacitors, and dirty outdoor coils round out the most common causes of heat pump breakdowns we encounter.

Our Heat Pump Repair Process

When our technicians arrive for a heat pump repair, we start with a full diagnostic that covers refrigerant levels, electrical components, the reversing valve, and the defrost cycle, rather than assuming the cause based on symptoms alone. Because a heat pump relies on several interconnected systems to work properly, an issue in one area often manifests as a symptom elsewhere.

Once we’ve identified the actual source of the problem, we explain what we found and what repair options make sense before any work begins. We carry parts for most major heat pump brands, which allows us to complete many repairs in a single visit. After the repair is finished, we test the system through both heating and cooling cycles to confirm it’s switching modes correctly and operating as intended.

Frequently Asked Questions

Why is my heat pump blowing cold air in winter?

A malfunctioning reversing valve, low refrigerant, or an issue with the defrost cycle often causes this.

Is ice on my heat pump normal?

Some frost during winter defrost cycles is normal, but heavy ice buildup usually points to a refrigerant or airflow issue that needs attention.

How quickly can you respond to a heat pump emergency?

Our 24/7 on-call service means a technician can typically respond the same day, including nights, weekends, and holidays.

Why does my heat pump run constantly without reaching the desired temperature?

This often points to low refrigerant, a failing component, or a system that’s undersized for the home’s heating and cooling demands.

Can a heat pump be repaired instead of replaced?

In many cases, yes. Our technicians diagnose the issue first and recommend repair when it’s the most practical and cost-effective option.
