Furnace Repair

The furnace in your home keeps the interior at a comfortable temperature on cold winter days. Because we may not use our furnaces in Northwest Houston as often as other parts of the country, it’s easy to forget about them. If your system won’t turn on when the temperature drops, simply give us a call, and we will determine what the problem is. We are also on call around the clock for emergency repairs. Call us anytime you need us.

Furnaces Spring

A twice-yearly furnace inspection and tune-up will keep your system running as efficiently as possible whenever you need it. During a furnace inspection, our heating technicians will do the following:

  • Check vent system for leaks or blockages
  • Lubricate all moving parts of the motor
  • Check heat exchanger for corrosion or cracks where carbon monoxide could escape
  • Check the seal of the blower access door
  • Inspect the air filter
  • Check blower and blower wheel for dirt and debris
  • And more

When you sign up for one of our furnace inspection plans, you are guaranteed two annual inspections and discounted or free services. During these visits, we can diagnose minor problems and fix them before they become bigger, more expensive problems. Regular maintenance also ensures that your furnace will be working properly over the lifespan of the system. Call today to learn about our three maintenance plans.
