Prescott furnace repair costs a $79 trip charge to start, waived if you approve the fix, and the flat-rate price is written before work. On windy bluff lots above the rivers, gusts can trip side-wall-vented furnaces, so we check the vent.

Furnace repair calls in Prescott homes

Prescott sits where two rivers meet under steep bluffs, and wind shapes a lot of furnace calls. On bluff-top and hillside homes, gusts across a side-wall PVC termination can upset the draft enough to trip the pressure switch, and the furnace locks out on the windiest nights. Drifting snow on exposed lots buries low terminations. We look at termination height and placement along with the switch itself.

In the older blocks above the riverfront, 1800s and early-1900s houses bring boilers, gravity furnaces converted to forced air, small basements and chimneys that have vented several generations of appliances. Draft and CO checks matter there. The mid-century ramblers and split-levels farther back have furnaces on their second or third generation, with igniters, inducers and control boards wearing out. St. Croix Gas supplies natural gas in town.

Furnace repair in Prescott: questions

Our Prescott furnace shuts off on windy nights. Why?

On a high-efficiency furnace with side-wall PVC vents, strong wind can disrupt the draft the inducer creates, so the pressure switch opens and shuts the burners off. Bluff and hillside homes catch the most wind. Sometimes a different termination kit, a new location or more height solves it, and sometimes a concentric or roof vent does. We check the switch, hoses and vent before deciding which.

We smell gas near the furnace at our Prescott house. Who handles that?

Leave the house first, then call your gas utility from outside. In Prescott that's St. Croix Gas, the local utility. Don't flip switches or use the phone inside. Once the utility has checked the leak and made it safe, call us to repair the furnace if it was involved.
