Did you know? Your HVAC system is what uses the majority of the energy in your home. If you want to keep control of those energy bills this winter, you need to make sure that your HVAC is working efficiently. It is important to have your system professionally serviced at least once, but preferably twice every year. You will also want to check your air filters regularly and make sure that they are clean. If you have dirty filters, not only is your indoor air quality affected, but your unit needs to work harder and use more energy!
