How to Prepare Your HVAC System for a Utah Winter

At 5,600+ feet elevation in Summit County, Coalville winters are serious. Temperatures below zero are common, and a heating system failure at 2 AM when it's -10°F outside is genuinely dangerous. Here's the comprehensive fall preparation checklist our NATE-certified technicians recommend every September and October.

1. Schedule a Professional Furnace Tune-Up

This should top every homeowner's list. A fall furnace tune-up includes heat exchanger inspection (safety), burner cleaning, ignition testing, flue inspection, and measurement of CO output — among 20+ other checks. Address any issues now, when parts and technicians are readily available, rather than during the first deep freeze of winter.

2. Replace Your Air Filter

Install a fresh filter at the start of heating season. A clean filter ensures proper airflow through your heat exchanger, which is critical both for efficiency and safety.

3. Test Your System Now

Don't wait for the first cold night to discover your furnace isn't working. Turn on the heat in September and let it run through a full cycle. Make sure every room warms up and that there are no unusual smells (burning dust on the first run is normal; gas smell or burning plastic is not).

4. Check CO and Smoke Detectors

Test every carbon monoxide and smoke detector in the home. Replace batteries in all units. The start of heating season is the highest-risk period for CO incidents.

5. Clear the Area Around Your Furnace

Remove any storage items, cardboard boxes, or flammable materials within 3 feet of the furnace. Check that the combustion air intake (the PVC pipe that supplies fresh air to the furnace) is clear of debris, bird nests, and ice.

6. Insulate Exposed Pipes

Pipes in unheated spaces (garage, crawl space, exterior walls) are vulnerable to freezing when temperatures plunge. Pre-formed foam pipe insulation from a hardware store is inexpensive and easy to install.

7. Seal Drafts

External air leaks make your heating system work much harder. Check weatherstripping around doors, caulking around windows, and the seal around plumbing penetrations through exterior walls.

8. Program Your Thermostat

Set up a heating schedule that balances comfort and efficiency. In Coalville, we recommend a minimum nighttime setback of 65°F — below 60°F risks frozen pipes in less-insulated areas.
