What’s different in Nokesville
In the village about seven in ten owner homes heat with electricity, and out here that usually means a heat pump: the unit cooling the house in July is the same one heating it in January. So there’s really no such thing as a cooling-only repair. A swollen capacitor or a pitted contactor will quit in whichever season comes next, and it’s a lot better found on a hot afternoon than on a cold night with the backup strips carrying the house.
On a big lot the outdoor unit usually sits in the open, next to lawn or field. Clippings from a riding mower, pollen and leaves pack into its fins, and a matted coil can’t shed heat, so the unit runs all afternoon, the pressures climb and it trips out on the hottest days of the year.
The village houses are old for central air. Close to four in ten went up before 1960, before central air was standard, so the cooling came later: new ducts threaded through an attic or a crawlspace, or the old heating ducts pressed into service, often with one small return. Starve the indoor coil of air and it freezes, and what you notice is warm air and a sweating air handler. The tech checks the airflow before anybody sells you refrigerant.
Across the rest of 20181 the houses are younger, and about a quarter went up between 2000 and 2009. A heat pump that came with one of those is somewhere past 17 years old now, and if it went in before 2010 it may still use R-22, a refrigerant nobody produces anymore. On one of those a leak is a fork in the road, and you get the repair number and the replacement number next to each other.
By the numbers

What you’d notice
If the fins on the sides of your outdoor unit are matted with clippings, it can’t get rid of heat and shuts itself off on hot afternoons. Clear a couple of feet around it, rinse the fins gently with a garden hose, and call if it still blows warm.
Ice on the outdoor lines in July means low refrigerant or starved airflow. Shut it off to thaw and call; running it iced can take out the compressor.
Usually the outdoor unit has stopped running. A hum with no fan turning is almost always the run capacitor; silence while the thermostat calls is usually the contactor.
Choosing who fixes it
Questions worth asking anybody who comes out, us included.
In most Nokesville houses the outdoor unit is the heat too. Ask whether the tech looks at the reversing valve and the defrost controls on a summer call, because a visit that skips them leaves January’s problem right where it is.
A company that prints what a capacitor or a contactor costs has already told you the number. One that won’t say until the tech is in your driveway hasn’t.
A healthy system drops the air somewhere around 16 to 22 degrees across the indoor coil. Low refrigerant means a leak, and topping it up every summer is the expensive way to find that out.
Some repairs aren’t worth doing on a 20-year-old system. The good answer shows you the repair price and the replacement price side by side and lets you pick.

Mr Lazo did a good jod, he answered all my questions and explained me the issues with my AC. Thanks Jaime.
Questions
Check the thermostat. An emergency heat or aux heat setting means a heat pump, and in the village, where about seven homes in ten heat with electricity, that’s the usual answer. In a propane house it can go either way: a heat pump with the propane furnace as its backup, or a plain air conditioner sitting on top of the furnace.
Not for the same type in the same spot. Prince William County’s replacement guidelines say a heat pump swapped for a heat pump needs no permit, and Nokesville has no town government to add one. Moving it, adding a unit or changing fuel is a different conversation, and the HVAC estimator prices a new system first.
The diagnostic visit is $99. The common repairs: a run capacitor $240 to $370, a contactor $290 to $425, a condensate drain cleared $175 to $420, refrigerant topped up $190 to $740. A refrigerant leak repair runs $1,850 to $2,700.
Fix the cheap parts on almost anything. Think twice about a big repair on a system over 15 years old, and about any leak on an R-22 system. The HVAC estimator prices a new system in about a minute, so you can put the two numbers side by side.
Ready when you are
Call, or send the form at the top. The tech prices the repair from the book before starting, and if it’s the end of the road you’ll hear that first.
