Cleaning is an important part of heating and air conditioning maintenance. Think of all the various components and moving parts that make up the heating, ventilation, and air conditioning system you rely on so much. One way that HVAC systems are kept clean is the ubiquitous air filter. Every kind of HVAC system, big or small, simple or complex, requires air filtration to continue to function properly. Contrary to common beliefs, climate control air filters are not meant to filter or clean the air you breathe in your home. That is done by using air purifiers. HVAC air filters filter out the foreign particles in the inner workings of your system, including dust, dirt, and hair. More advanced air filters are more efficient and can even capture finer particles like pollen, mold, and other allergens. It’s a shame that people forget to change these air filters on a regular basis, as this causes all sorts of unnecessary and easily avoidable problems to arise. Other parts of your HVAC system benefit from cleaning. Dirty evaporator coils, for example, will hinder an HVAC unit’s ability to properly cool down your home, and this can be a big issue. You should also keep the condensor free of dirt and yard debris that can hinder the fan blades from spinning or cause other problems. Call your local HVAC company for a maintenance visit and ask what kind of cleaning is included. Your air ducts may also need to be cleaned, which is a service that is often provided at a reasonable price.
