AC Repair Services in Newtown Square, PA
- Locally Owned & Operated
- Trust & Transparency
- Long-Term Relationships
Newtown Square covers a lot of ground, and the newer construction spread across it leans heavily on heat pumps. That changes what summer service looks like, because a heat pump in cooling mode carries components a straight air conditioner does not, and it fails in ways a conventional system never will.
Davis Modern Heating & Cooling repairs both across Newtown Township and the surrounding Delaware County communities. We have been family owned since 1850, we service every brand, and we work on heat pumps, conventional split systems, and dual fuel setups with equal familiarity.

Heat Pump and Central Air Repair in One Visit
In cooling mode a heat pump does what an air conditioner does, but it carries a reversing valve, a defrost control, and additional sensors that a cooling only system does not have. A stuck reversing valve can leave a home getting warm air in July with everything else appearing to operate normally, and it is a diagnosis that gets missed when a technician assumes a standard system.
Our repairs cover capacitors, contactors, condenser and blower motors, reversing valves, defrost boards, sensors, refrigerant leaks, coil cleaning, condensate drains, and thermostat and control faults. On dual fuel systems we also verify that the changeover logic is set correctly, since incorrect settings waste money quietly in both seasons.
Where a system is finished, we explain replacement options across electric, natural gas, propane, and heating oil, and we bring more than thirty five years of geothermal experience for properties with land available for a ground loop.
What Your Heat Pump or AC Is Telling You
These symptoms are worth a call regardless of which type of system you have.
- Warm air during cooling
- Outdoor unit not running
- Loud clunk at changeover
- System running constantly
- Ice on the lines
- Humidity staying high
- Auxiliary heat in summer
- Breaker tripping repeatedly
- Water near the air handler
- Energy costs climbing
Heat pump specific symptoms are especially worth mentioning when you call, since they point us in a very different direction.
Why Heat Pumps Work Harder Out Here
Properties in Newtown Square tend to be larger and more spread out than in the boroughs closer to the city, and a good share of the newer homes are sizable with open plans and significant glass. A heat pump serving that kind of house runs long cycles in summer, which is efficient by design and still hard on components across years of service.
Rolling terrain plays a role as well. Homes sited on open rises catch full afternoon sun with little shelter, while others sit in low pockets where humid air settles overnight and lingers into the morning. Two properties a mile apart can put meaningfully different loads on identical equipment.
The equipment here is also younger on average, which means failures skew toward electronics and controls rather than worn out compressors. Boards, sensors, and communicating thermostats account for a growing share of what we diagnose, and they need a different approach than a simple capacitor test.
Heat Pump Repair Over in Liseter
Mark called from Liseter in July because his system was running but the air from the vents felt warm. Everything sounded normal outside, and the thermostat was set where it should have been.
Our technician confirmed the reversing valve had not shifted into cooling and traced it to a failed solenoid coil rather than the valve body itself. We replaced the coil, verified the changeover under load, checked refrigerant pressures and temperature split, and cleaned the condenser coil while on site.
The house was cooling within the hour. It is a repair that sounds alarming and is usually straightforward, and it is one of the reasons it matters that whoever shows up actually knows heat pumps.

Frequently Asked Questions
Why is my heat pump blowing warm air in the summer?
That usually points to a reversing valve or its solenoid failing to shift into cooling mode. It is a heat pump specific fault and it needs a technician familiar with them.
Do heat pumps need service twice a year?
Ideally yes, since they operate in both seasons and accumulate roughly twice the runtime of a cooling only system.
Is emergency service available?
Yes. We have technicians on call 24 hours a day, seven days a week, all year.
What is dual fuel and do you service it?
Dual fuel pairs a heat pump with a fossil fuel furnace and switches between them based on outdoor conditions. We service and configure those systems, including the changeover settings.
Do you repair geothermal heat pumps?
Yes. We have more than thirty five years of experience installing and servicing geothermal systems.
