Mini-split flashing a code, one room suddenly not cooling, or water dripping down the wall from the head? Tell us what it is doing and the model if you can reach it, and we will track down what is actually wrong before we touch a part.
When a mini-split acts up, the trouble can sit in the indoor head, the outdoor unit, or the line running between them. A weak room, a water leak, a blinking error light: any of those can start in more than one place, so guessing wastes your money. We find the real source first.
A quick note on what we handle: home mini-splits, both the single-room kind and the multi-room kind. Big commercial VRF systems are outside what we do. If you can safely read the indoor and outdoor model numbers, send them along and it speeds up the whole visit.
An error code tells us where to look. It does not prove which part failed. We identify the system and test the circuit, sensor or connection the code points to before we call anything the cause.
On a multi zone system, whether one head is faulty or the outdoor unit is failing to serve it changes the entire repair. We establish that before going further.
We check relevant connections, refrigerant lines, drains and settings. If an installation issue contributes to the problem, we explain the evidence.
We check the repaired function and affected zones as conditions permit, and explain any remaining fault or testing limit.
We serve homeowners in Germantown, Gaithersburg and Montgomery Village.

"This is a good company. They helped me out with my new hvac equipment for three systems in the home. The systems where over 20 years old."
Google"Really happy with the work. They showed up on time, did a great job, and were easy to work with. I'd definitely recommend them for HVAC or home improvement work!"
Google"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."
