What’s different in Bluemont
Start with the weather you actually get. Mount Weather, up the mountain, has a July average high of 82.4 degrees and 848 cooling degree days a year. Purcellville, the valley comparison for the village, runs 86.4 and 1,050. A system that cannot hold the house on an ordinary July day has a fault, not a weather problem. The diagnostic visit, $99, finds the fault, and the repair is priced before we start it.
Hail and trees are the local causes. Ping-pong-ball hail fell near Bluemont on June 16, 2023, and winds on October 31, 2019 downed numerous trees and closed roads in the village. A unit that runs but cools poorly after weather like that may have bent fins or a coil packed with debris, which a cleaning and a look can settle. If the fan turns slowly or hums, the capacitor is the usual first suspect at $240 to $370, and a pitted contactor is $290 to $425.
Your furnace may be part of the story. About one owner home in seven in ZIP 20135 burns propane, and in a house with a furnace the blower that heats in winter also moves the cooling air in summer. A worn blower wheel shows up as weak airflow at the registers and a coil that ices over; replacing the wheel is $300 to $440. Where electricity is the heat, 54 percent of owner homes, the indoor unit may be a heat pump’s air handler doing the same job.
Housing age sets the odds. Nearly half of the owner homes in ZIP 20135 predate 1980, about a third predate 1960, and the median is 1981. In houses like that, the duct and drain runs can be far older than the air conditioner attached to them. A clogged condensate line shuts a system down to protect the ceiling below it, and clearing it is $175 to $420.
By the numbers
From the Census Bureau’s 2020 to 2024 survey. Median year built and heat count owner-occupied homes only.
ZIP 20135 as a whole: about seven in ten of its homes are in Clarke County, most of the rest in Loudoun around the village, and a few in West Virginia.
What you’d notice
On afternoons when heat indices in Western Loudoun pass 110, as they did on July 28, 2023, a weak capacitor or a hail-bent coil leaves the system running for hours while the house creeps up. If yours runs all day and loses ground in July, the weather is not the explanation. Something in the system needs a look.
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.
A tech who knows Bluemont looks at the fins, the fan and the drain before quoting parts, because hail and storm debris can make a healthy system look weak. Ask for the price of the repair in writing before the work. If the part is cheap and the real trouble is a bent coil, you should hear that first, not after the part is on.
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.

Moises and his team responded quickly to our need for a new AC. They were efficient, friendly, and professional throughout the process. I will happily call SwiftPro for any of my hvac and plumbing needs.

Questions
Check the filter, the thermostat and the breaker. Then look at the outdoor unit. If the fan is not turning while the compressor hums, a failed capacitor is a common cause, $240 to $370, and a worn contactor is $290 to $425. Ice on the indoor coil points to airflow. Anything past that gets a diagnostic visit, $99, so the fix is priced before we start.
In summer a heat pump cools with the same outdoor parts as an air conditioner, so the same fan, capacitor and contactor checks apply, and the diagnostic is $99. In winter that unit runs a defrost cycle to clear frost, which matters on this slope, where Mount Weather logs 104.7 days a year with a low at or below 32 degrees.
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.
