The Fairfax22036 calls we answer most often
If your system is doing any of the following, it is worth a diagnostic before the fault gets more expensive.
Refrigerant leak at a flare or coil connection

Loud banging on start-up (compressor slugging)
Short cycling — on and off every few minutes
One or two rooms that never reach the set temperature
Furnace lights then shuts down after a few seconds
Heating and air conditioning service built around Fairfax
Nobody in Fairfax wants to spend a day waiting on a technician with a four-hour window. We quote a 60-90 minutes target response time for this ZIP and hold crews locally so that number is realistic.
A large share of the equipment we service in Fairfax was installed by a builder to a minimum spec. That usually means an undersized return, a cheap filter rack and a condenser sitting close to a wall.
Because Virginia runs heat pumps and gas furnaces with central air, the transition between seasons is when we see the most emergency calls — equipment that sat unused for months.

Fairfax22036 HVAC questions, answered
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.
Do you service commercial and light commercial properties?
Yes. Around Fairfax 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.
Why is my furnace short cycling?
Short cycling in Fairfax 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.
Do you handle ductless mini-split systems?
Yes. Ductless installations have grown quickly in Virginia, particularly in older homes without existing ductwork. We service indoor heads, clean filters and drain lines, check line-set insulation and diagnose communication faults between heads and the outdoor unit.
What causes water to leak from the indoor unit?
Almost always a blocked condensate drain line, a failed drain pan float switch, or a frozen coil melting faster than the pan can handle. In Fairfax we see algae and dust clogging drain lines constantly during May through September. It is a fast fix but ignoring it ends in ceiling damage.
How quickly can a technician get to Fairfax?
For the 22036 service area our target response time is 60-90 minutes from the moment dispatch confirms your address. Real-world timing depends on the day — the first sustained heat or cold snap of the season is always our busiest period — but we hold technicians locally specifically so that window is achievable rather than aspirational.
