Furnace Repair Services

The cost of furnace repair depends on the part that failed, your furnace’s make and model, how easy the furnace is to reach, and whether the part is still under manufacturer warranty. Smaller repairs like a flame sensor, ignitor, or capacitor cost much less than a blower motor, inducer motor, or control board. Because every furnace and every home is different, a firm price comes after the technician sees the system. We diagnose the problem first and give you a written estimate, and no repair begins until you approve it. For larger repairs, ask about our financing options.

A repair is usually the right call for a furnace in good condition and under 15 years old. A good rule of thumb: consider replacement when the furnace is 15 or more years old, or when a single repair would cost more than a third of a new system. Frequent breakdowns, rising gas or oil bills, uneven heat, and a cracked heat exchanger also point toward replacing. Our technician will tell you honestly which choice makes sense and why. If replacement is the better value, we’ll give you a written quote for furnace replacement so you can compare both options.

Yes. Along with gas furnaces, our technicians repair oil furnaces and electric furnaces throughout the area. Oil furnace repairs often involve the burner nozzle, oil filter, fuel pump, ignition transformer or igniter, electrodes, and cad cell, and we clean and adjust the burner so it fires cleanly. Electric furnace repairs usually come down to heating elements, sequencers, relays, limit switches, or breakers. Oil heat is common in older homes and areas without a gas main, while electric furnaces show up in condos and additions. Whatever fuel heats your home, you get the same diagnosis first and the same written estimate.

Yes. High-efficiency condensing furnaces, the ones vented with white PVC pipe, need a few checks that older furnaces don’t. They make water as they run, so we inspect the condensate trap, drain line, and pump, and we make sure the intake and exhaust pipes outside aren’t blocked by snow, ice, leaves, or nests. Many use variable-speed blowers, two-stage gas valves, and brand-specific control boards, so our technicians read the furnace’s diagnostic codes and follow the manufacturer’s procedures. That gets the repair right the first time and helps protect your warranty.

It depends on the symptom. Turn the furnace off at the thermostat and call us if you smell burning plastic or an electrical odor, see water pooling under the unit, or hear loud banging when it starts. If you smell gas, leave the house and call your gas utility from outside. If your carbon monoxide alarm sounds, get everyone outside and call 911. A furnace that simply runs longer than usual or makes a new sound can usually keep running until our technician arrives. Don’t keep resetting a furnace that locks out again and again, because that can hide a bigger problem and damage parts.
