Signs Your Furnace Needs Attention
Most furnace trouble shows up as something you feel or hear before the system quits for good. Call for service if you notice:
- Rooms that never reach the thermostat setting, or air from the vents that feels cool
- A furnace that starts and stops every few minutes, or runs without stopping
- Banging, squealing, grinding, or rattling when the burners or blower come on
- A burning or electrical smell that lasts past the first few days of the season
- Heating bills that climb while your thermostat settings stay the same
If you ever smell gas, leave the house first and call your gas utility from outside.
How We Diagnose and Repair Furnaces
The same symptom can come from very different failures: a dirty flame sensor, a failed igniter, a weak inducer motor, a blocked flue or condensate line, a bad control board, or an airflow problem in the ductwork. Our technicians test the system step by step until they find the actual cause, instead of replacing the part closest to the symptom. You get a plain explanation and the price before any work starts, and the most common parts ride on the truck, so most repairs are finished the same visit.
Repair or Replace Your Furnace?
Most furnaces are worth repairing. When a system is over 15 years old, needs a major part like a heat exchanger, or keeps breaking down, replacement is often the better money. We tell you which way makes sense and why, and our furnace installation team sizes any new system to the home.
Furnace Tune-Ups and Maintenance
A yearly tune-up catches weak igniters, dirty burners, and worn parts before they turn into a no-heat call in January. Book a heater tune-up before the cold weather, or join one of our maintenance plans to stay on schedule every year.
Gas, Oil and Electric Furnaces
We repair every type of furnace on all major brands. Gas furnace repair centers on ignition, burners, venting, and the heat exchanger. Oil furnace repair covers the burner, nozzle, filter, and combustion testing. Electric furnace repair focuses on heating elements, sequencers, and breakers.
Water Heater and Thermostat Service
Water Heater Repair and Replacement
A water heater usually sits right next to the furnace and often shares its venting and gas line, so our technicians can check both on the same visit. We repair and replace gas, electric, and tankless water heaters, fix leaks and pilot problems, and replace aging tanks before they fail. Learn more about our water heater repair service.
Thermostat and Indoor Air Quality Service
Some no-heat calls turn out to be a failing or miswired thermostat, and a smart thermostat can cut heating costs once the furnace is running right. We install and set up programmable and smart thermostats, and add whole-house humidifiers and air cleaners that keep winter air from feeling dry and stale. See our thermostat services.
Emergency Furnace Repair
When a furnace quits in freezing weather, it stops being an inconvenience fast, especially with young kids, older family members, or pipes at risk. No-heat calls get priority, with same-day service and fast response any time through our emergency HVAC services.
