Heating and air conditioning service built around Gaithersburg
If your heat pumps and gas furnaces with central air has started short cycling, blowing warm air or making a noise it never used to make, you are not alone — Gaithersburg generates some of the highest call volume we handle in Maryland. Hot humid summers and winter cold snaps keep both heating and cooling in regular use.
Homes in Montgomery County tend to be a mix of older builds with original ductwork and newer infill construction, which means airflow problems show up very differently from one street to the next.
Peak cooling demand here runs May through September. Booking a tune-up in early spring means you are not competing with the whole neighbourhood for a tech in July.

Gaithersburg20884 HVAC questions, answered
How often should I change my filter in 20884?
Monthly inspection and replacement every 60 to 90 days is the baseline. Homes in Gaithersburg with pets, ongoing construction nearby, or a high-MERV filter in an undersized return should move to monthly changes. A loaded filter is the single most common cause of frozen coils and failed blower motors.
Should I repair my system or replace it?
The usual rule of thumb: if the repair costs more than half the price of a replacement and the equipment is over ten years old, replacement generally wins. We will run that comparison with you on site and show you the maths — and if the honest answer is a $180 capacitor rather than a $9,000 system, that is the answer you get.
Why is my furnace short cycling?
Short cycling in Gaithersburg most often comes from a restricted airflow path — a loaded filter, a closed register, an undersized return — or from an oversized unit. It can also be a failing flame sensor or a pressure switch fault. We measure static pressure and temperature rise before concluding anything, because guessing at this one is expensive.
What brands do you service in Gaithersburg?
All of them. Our 20884 technicians are trained on Mitsubishi Electric, American Standard, Rheem, Bryant and essentially every other residential brand sold in Maryland, including discontinued lines. We keep a broad parts catalogue on the trucks for exactly that reason.
Is my carbon monoxide risk something I should worry about?
With any combustion appliance, yes. A cracked heat exchanger can spill carbon monoxide into the living space, and it is odourless. We perform combustion analysis and a CO test on every furnace and boiler call in Gaithersburg, and we recommend a working CO alarm on every level of the home regardless of who services your equipment.
Do you service commercial and light commercial properties?
Yes. Around Gaithersburg we handle rooftop packaged units, split systems, VRF/VRV installations and building automation faults for offices, retail, restaurants and multi-tenant buildings, including after-hours scheduling so you are not disrupting trade.
