If your home has some rooms that run hot while others run cold, you may need to upgrade to a zoned HVAC System. A zoned heating and cooling system uses dampers in the ductwork to regulate and redirect air to specific areas of the home. This allows for the creation of customized temperature zones throughout the home for increased comfort and efficiency. Call Barrett Heating & Cooling today for a free estimate! 618-465-3731 or online at barrettheating.com.

The quality of the air in your home can have a profound effect on your health. The air pollution inside your home is often twice or even 5 times that of the air outside.

But don’t worry, the air comfort professionals at Barrett Heating & Cooling, Inc. have the solutions to make the air circulating through your home safer and healthier. Contact us today at 618-465-3731 to schedule an appointment to discuss the options that will best fit you and your family.

A malfunctioning heating system that refuses to turn on can be distressing. However, it doesn’t always indicate a major problem.
Sometimes, minor problems prevent the system from starting. Check for issues like a tripped circuit breaker, thermostat settings, or a blown fuse. Faulty ignition controls or a pilot light that won’t stay lit can lead to startup failures. Our technicians can diagnose the issue and get your furnace running fast.

Have you checked your furnace filter lately?

A dirty or clogged filter puts more strain on your system and reduces efficiency, causing your system to run for longer periods of time to heat your home. This is a simple maintenance issue you can fix yourself, but if you don’t feel comfortable doing it or just don’t have the time, check into our annual maintenance plans. We’ll make sure your system is properly cleaned and in good condition to keep your family warm.
