Seasonal HVAC Tune-Ups in Broomfield

Downslope wind events around Rocky Flats can loosen sidewall vent terminations, blow debris into intake pipes, and shift outdoor units off their pads. In the fall we inspect the furnace intake and exhaust outside, check access panels for a tight seal, and confirm the condenser is level. An unsealed blower door can let a furnace pull air from around itself, so we treat that as a safety item.

The 1950s first filing has smaller mechanical spaces and furnaces that may vent through a shared metal flue with the water heater. When one appliance has been replaced, the shared vent sometimes no longer suits both. We check draft, look at the vent connector, and test for carbon monoxide at both appliances. The furnace also gets a gas pressure check against the high-altitude table; at about 5,350 feet, that means a derate of roughly 21 percent.

Average relative humidity here is under 50 percent year-round, and much lower indoors in winter. Bypass humidifiers mounted on the furnace need their water panel replaced and the drain line checked each fall. A stuck solenoid that drips water into the furnace is one of the more common problems we find.

Every fall visit includes a carbon monoxide test at the furnace and in the house, a check for working CO alarms near bedrooms, flame and burner inspection, igniter and flame sensor service, temperature rise, and a safety-control test. Every spring visit includes a coil cleaning, refrigerant pressure and temperature readings, electrical testing, and a drain check. You get written findings, and any repair is priced in writing before we start.

Schedule the furnace visit in September, before the early-October freeze typical of Denver-area records, and the AC visit by May. If your system is newer, keep the tune-up invoice with your manufacturer registration: brands such as Trane give a longer parts warranty only when the equipment is registered within 60 days of installation.
