Heating and air conditioning in Westminster
Most Westminster homes went up between the late 1960s and the 1990s, around Standley Lake and along US 36. That puts a lot of them on furnaces and air conditioners that are 20 to 30 years old.

Homes we work on in Westminster
1970s and 1980s two-stories and bi-levels
Furnace in the basement, condenser in the side yard. The upstairs bedrooms run warm in summer through ducts that were never resized.
1990s homes around Legacy Ridge
Bigger houses, sometimes with two systems or two zones. A zone damper stuck open or shut is a common reason one floor is off.
Bradburn and newer infill
Mechanical closets with little room around the furnace. A replacement there needs careful measuring for the unit and its venting.
What we fix most often in Westminster
- Air conditioners still on R‑22
- Many 1990s systems still run on R‑22. Production and import of R‑22 ended in the United States on January 1, 2020, so repairs rely on recycled refrigerant and cost more. You can keep the system running. When it needs a big refrigerant repair, replacing it usually makes more sense.
- Hot upstairs in July
- We measure the temperature at each supply register. A closed damper or a blocked return often explains it before anything needs replacing.
- Hail along US 36
- Condensers in open backyards take direct hits. Plan members get a fin and coil check after every big storm.

Furnace quit at 11 pm on the coldest night of the year. A person answered, Dana called back in ten minutes and the heat was back on before 1 am. She showed me the cracked igniter before replacing it.

Is it worth recharging an old R‑22 air conditioner?
A small top-off on a system you plan to replace soon can be. A leaking R‑22 system usually isn't worth fixing, because the refrigerant alone can cost more than the visit. We show you both numbers.
Do you charge more to come to Westminster?
No. Anywhere in our area the visit is $89 during office hours, credited to the repair if you go ahead the same day, and $179 at night, on Sundays and on holidays.
