Most people are now aware that indoor air pollution is an issue of growing concern and increased visibility. If you use your heater or air conditioning on a regular basis over time indoor pollution, pollen, dirt, and debris can build up in your duct system. A dirty duct system can affect your indoor comfort and health leading to allergies and asthma. If someone in your family is suffering from these respiratory conditions, contamination in your ductwork may be to the problem. The United States Environmental Protection Agency (EPA) recommends that you maintain your HVAC system and keep your ducts clean in order to maximize indoor comfort and occupancy health.

Regular maintenance is required in order to ensure that your heating and air conditioning unit is working at tip top performance. A well-maintained system can improve indoor occupancy comfort and reduce your energy bill. We recommend that you perform preventative maintenance every 6 months. Our maintenance services include: 1) cleaning out debris from your machine, 2) recharging your refrigerant, 3) checking the electrical control board, 4) checking thermostat settings, 5) tightening all electrical connections and measuring voltages, 6) lubricating all moving parts, 7) checking and inspecting the condensate drain, 8) cleaning and adjusting air blower components, and 9) changing out air filters.
