Your HVAC system is integral to your family's comfort and the value of your home. Issues with your furnace or heater can actually impact your energy bills and air quality throughout the year. Here are a few warning signs that it might be time to contact a technician to take a look at your heating system.
Whistling or Sucking Sounds near the Vents
Your vents should be relatively quiet whenever you have your HVAC system on. When they begin to make unusual whistling sounds, you could be dealing with a clogged filter. Air filters are relatively cheap, and these products are your first line of defense against airborne contaminants within your home. They generally need to be changed once every month or two throughout the year.
Knocking or Clinking Sounds
Most furnaces produce at least a little noise, but they shouldn't continuously rattle and knock. Within a few moments of being turned on, heating systems should only produce a subtle whirring or sucking sound. Any banging or rattling sounds could be coming from loose or damaged parts that must be replaced or repaired immediately.
An efficient HVAC system can keep your entire home at a relatively consistent temperature. Families who notice distinct temperature variations between rooms might want to speak with an HVAC technician about inspecting the heating and cooling systems. Uneven heating could be the result of damaged parts, clogged filters, or any other number of unique problems.
Drastic Changes to Your Energy Bills
With a well-maintained HVAC system, energy bills will stay relatively consistent over the years unless major changes are made to the home. Due to the fact that your HVAC system could account for over half of your energy consumption, you must have it inspected immediately if your energy bills skyrocket.
