The quality of your furnace determines your comfort all winter long, and not just in terms of temperature. A poorly functioning furnace can fail to heat your home, make unpleasant noises, use too much electricity, and even reduce your home’s air quality and safety over time. A broken furnace can become dangerous as outside temperatures drop toward (or below) freezing in the colder months.
Is your furnace not heating? Is your furnace making strange noises, creating an unpleasant smell, or setting off your carbon monoxide detectors? If so, General Air is here to care for all your furnace repair needs quickly and with compassion.

Common Reasons for Furnace Issues
Why do furnaces stop working? Your furnace may be malfunctioning or acting up for several common reasons. Let’s look at the most likely reasons you need furnace repair.
Cleaning or Replacing Filters
If your air filter goes too long without change, it can damage your HVAC system. If there is too much clog, your blower fans will have to work extra hard, which uses more electricity and increases the chance of a blower fan blow-out. Too much dust from a dirty filter can cause damage as grit gets into the machine or dust starts to burn on the heating coils.
Fixing Faulty Components
Not all your furnace parts wear out at the same rate. Fans wear out the fastest, followed by the heating element, exchange, and wires. If any part of your furnace has broken or dysfunctional parts, you will need a professional furnace parts replacement before your heat works properly again.
After a quick inspection, your HVAC technician should be able to tell you if your heating system has any broken or dysfunctional parts and recommend any furnace repairs you may need.
Thermostat Troubleshooting
Sometimes, it’s not the furnace but the thermostat causing problems. Call General Air to troubleshoot the issue or install a new thermostat if your thermostat is broken or malfunctioning. Installation of a new thermostat might be your opportunity to upgrade to a smart thermostat.
Importance of Regular Maintenance
Poor furnace maintenance can eventually lead to trouble. If your furnace has not been cleaned or inspected for several years, poor performance may lead to necessary furnace repairs.
