Signs Your Heater Needs to Be Serviced

Signs Your Heater Needs to Be Serviced

If you suspect your system has an issue, don’t attempt the complicated & time-consuming process of trying to diagnose it (or fix it) yourself. Our technicians have the expertise to get to the root of the problem safely. Here are some signs you should call us to service your heater:  

Odd smells coming from the heating system
Cool air temperatures
Cycling on and off frequently
Weird noises like squeals, banging, thumping, or hissing coming from the heater
Thermostat issues
Discolored pilot light
Poor air quality
Carbon monoxide detection (serious!)
Increase in energy bills

While some issues may only warrant a repair – more serious problems with older systems might require a full heater replacement. Regardless of what you need, our experts will offer the best solution at the best possible price.

I've always been pleased with the expert service from Indoor Comfort Systems. Their preventive maintenance program helps ensure my HVAC system runs with utmost efficiency. Their installation of my new system a few years ago was superb. I couldn't ask for a better job.
