Heating and air conditioning service built around Herndon
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 — Herndon generates some of the highest call volume we handle in Virginia. Humid tidewater summers and colder mountain winters mean equipment needs vary sharply across the state.
Around Herndon, condensate drainage is a recurring fault. Blocked drains and failed float switches cause more water damage claims here than actual refrigerant failures do.
Heating season here is November through March. A pre-season inspection catches cracked heat exchangers and failing igniters before the first real cold snap.

Herndon20170 HVAC questions, answered
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 Herndon 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.
Do you service commercial and light commercial properties?
Yes. Around Herndon 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.
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.
How often should I change my filter in 20170?
Monthly inspection and replacement every 60 to 90 days is the baseline. Homes in Herndon 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.
Do you offer maintenance plans?
We do. A two-visit plan in Virginia covers a spring cooling inspection and an autumn heating inspection, priority scheduling during peak weeks, discounted repairs and no diagnostic fee. Members rarely end up on the emergency list.
