We repair, replace and maintain home air conditioners, heat pumps, ductless systems, hot water boilers, and gas or propane furnaces. Tell us what it is doing. We find the real cause first, then tell you the fix and the price before anything gets done.
Heating and CoolingEquipment InstallationClear Written Scope
Heating and Cooling in Germantown, Gaithersburg and Montgomery Village
Mora Heating & Air works on home AC, air-source heat pumps, ductless systems and gas or propane furnaces. Oil-furnace service stays with your oil provider. We do not take on commercial, geothermal or VRF systems.
We work across Germantown and the nearby Montgomery County towns. Whatever the system is doing, we find the cause, then tell you what we found and what it needs before you decide a thing. We do not build or repair ductwork.
What We Work On
AC Repair. Diagnosis for cooling problems, with the proposed repair explained.
We check the electrical, the temperatures, the airflow and the refrigerant to find what is actually wrong. For gas and propane furnaces we also check the combustion side. Oil-furnace checks belong with your oil provider.
You should always be able to ask what we found, how we checked it, and what we are still not sure of. We tie the fix we recommend to what the system is actually doing, and we say so if more testing is needed.
One room that never feels right can come from the thermostat, the airflow, the house itself, or the equipment. We look at all of that before telling you to replace anything. New equipment alone will not fix a duct problem, and duct work is not something we take on.
When It Is Worth Calling
The system runs but the house never reaches the setting
Air is moving from the vents but it's not the temperature it should be
The equipment starts, runs briefly, then shuts down and starts again
Ice on the outdoor unit in cooling season, or ice that never clears in heating season
Water around the indoor unit, or a stain on the ceiling below an attic air handler
A breaker that trips whenever the system calls
Bills climbing without any change in how you use the system
One room that has never been comfortable no matter what anyone has done to the equipment

"I had a water leakage in my HVAC unit and Jay came out and did an amazing job on the repair. It took him longer than expected and he was working later into the night but made sure everything was done properly and efficiently. Super grateful for Jay's hard work and will definitely be reaching out for any future HVAC repairs I need!"

"I am generally cautious when hiring service technicians, as I prefer to handle equipment maintenance myself whenever possible. However, the team sent by Mora Heating & Air completely earned my trust. When my AC compressor failed during a recent heat wave, two other supposedly reputable companies immediately pressured us to buy an entirely new system. In contrast, the technicians from Mora Heating & Air did not attempt to upsell us. Instead, they provided a practical, targeted solution: replacing only the compressor and the crankcase heater. Choosing this route saved us a significant amount of money. I highly appreciate their honesty and professionalism, and I will certainly continue using their services in the future."

"Jay & his team are my goto for HVAC problems. Weather it's a small repair like replacing a capacitor or larger project like full system replacement. Jay and his team @ Mora Heating & Air do quality work at an affordable price but add top rated customer service that many large companies just can't & don't give."
