Seasonal HVAC Tune-Ups in Sherrelwood

A single small return grille is common here, and it makes the system sensitive to dirty filters. We measure temperature rise in heating and static pressure, check the filter and blower wheel, and look for returns blocked by furniture or closed off by remodeling. If the readings are outside the manufacturer's range, the report says so and suggests a fix, such as a different filter or added return capacity.

Ducts in Sherrelwood ranches often run through a crawlspace or attic. Where we can see them, we look for disconnected joints, crushed flex runs and missing insulation, which waste heat in winter and cooling in summer. Those are often cheap to fix once they are found.

Evaporative coolers need attention twice a year. In spring we replace the pads, clean the reservoir, check the pump, float valve, belt and motor, and make sure the unit isn't leaking onto the roof. In fall we drain it, blow out the water line so it won't freeze, and close the damper or cover the ceiling vent. A cooler duct left open over winter pulls heat straight out of the house.

For homes with central air, the spring visit cleans the condenser coil, tests the capacitor and contactor, tightens electrical connections, checks refrigerant readings and the temperature drop across the indoor coil, and clears the condensate drain. On small lots, we also check that the condenser isn't boxed in by fences, shrubs or a dryer vent. Older R-22 units get a close look for oil stains at fittings, since a leak usually means planning a replacement.

Check filters monthly in winter and summer. During wildfire smoke, EPA recommends MERV 13 filtration if the system can handle it; with small returns, we measure static pressure before recommending one. If you have a furnace humidifier, we replace the pad and check the valve each fall. Swamp coolers add moisture in summer but should be off and closed during smoke events.

Colorado requires CO alarms within 15 feet of each sleeping room entrance when a home with gas appliances or an attached garage is sold or has permitted appliance work. An annual check of every fuel-burning appliance is what the CPSC advises. Book furnace visits in September and cooling or swamp cooler start-ups in April or May. A tune-up involves no permit, though a replacement furnace or AC does, through Adams County. Our tune-up checklist covers every step.
