What’s different in Bristow
In Linton Hall, the Census place covering roughly two thirds of 20136, about three homes in four went up after 2000, and the median owner home in 2004. So the outdoor unit that came with a typical Bristow house passed twenty a couple of summers ago. Plenty have been replaced once already. Plenty haven’t, and on those the label plate on the side of the condenser is the first thing worth reading, because it carries the year it was built and the refrigerant inside.
That refrigerant line matters more here than in most towns. Equipment built before 2010 mostly ran R-22, and building in Bristow carried on straight through the switch to R-410A, so two houses on one street can hold two different refrigerants. On R-410A a leak is a repair question. On R-22 it’s a budget question: the refrigerant has been out of production since 2020, a recharge means reclaimed stock, and a system past twenty rarely earns that.
Two in three homes here are detached, and a two-story single-family house from those years often carries two systems: one for the main floors and one for the bedrooms, with its air handler up in the attic. In July the attic unit works hardest, and its condensate line runs above a finished ceiling. When only the upstairs is warm, that second system is usually the one to look at, not the whole house.
The county paperwork is light. Prince William asks for no permit to repair an air conditioner with replacement parts, or to swap an outdoor unit or a heat pump for the same type in the same spot. A new location is a different story in an HOA neighborhood. Victory Lakes, with 609 townhouses among its 1,296 homes, says owners may need an Application for Exterior Modification reviewed by its Covenants Committee before changing the outside of the house, and a condenser on a new pad is that kind of change.
By the numbers
From the Census Bureau’s 2020 to 2024 survey. Median year built and heat count owner-occupied homes only.
What you’d notice
In a two-system house that points at the attic unit, not the whole house. Check that system’s filter and its breaker first. If both are fine and the bedroom registers still blow warm, it’s a service call for that one system.
A house from the 2000s often still has its first air conditioner. Anything installed before 2010 usually runs R-22, which hasn’t been made since 2020, so a leak on one is a repair-or-replace question.
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.
The plate on the side of the outdoor unit gives the year it was made and the refrigerant it runs. On a house from Bristow’s 2004 median, that answer turns a leak into either a repair or a replacement conversation, so you should hear it before any price.
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.

Questions
Not for a repair with replacement parts, and not for swapping an outdoor unit or a heat pump for one of the same type in the same spot. A new gas furnace going in beside it is different: the county wants a permit for that every time.
Finding and fixing the leak runs $1,850 to $2,700, but the refrigerant to refill it is reclaimed stock now, priced by whatever that summer’s market is. On a unit past twenty, that’s the moment to set the replacement figure beside the repair; the HVAC estimator gives you one.
Ask the association first. Its Covenants Committee reviews changes to the outside of the house, and a unit on a new pad is one. The county’s exemption covers a same-type unit in the same location only, so a move can mean a permit as well. A repair needs neither.
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.
