Your heating and air conditioning system naturally loses energy efficiency over time. This loss of efficiency is due to many factors, including dust and dirt, natural wear and tear, and buildup in drains or on burners. Keeping your heating system maintained with regular professional tune-ups can help to reduce these factors. During your tune-up, your maintenance technician will clean and check over your heating equipment, identifying areas of wear and tear. They can identify failing parts in need of replacement before they become a serious problem. A tune-up alone may instantly improve energy efficiency by up to 30%. You’ll also enjoy cleaner air and a cleaner residence because your HVAC system will be distributing clean air through a clean air filter. Perhaps one of the greatest benefits you’ll enjoy following a fall furnace or AC tune-up is decreased utility bills. A neglected HVAC system must work much harder to heat and cool your home, while a furnace or air conditioner that has been finely tuned can take less energy to maintain indoor comfort. Because your heating system will function more efficiently, it will deliver superior heating at lower cost than you otherwise may have had through the winter season.
First, check to be sure that your thermostat is set to “heat” and not “cool,” and ensure that the fan is set to “auto.” Then, check to be sure that the thermostat is set to a temperature high enough to trigger the furnace to emit heat. If your thermostat is properly set, ensure that it is getting power — check batteries, fuses and circuit breakers — and ensure that the interior components are clean. Dust and debris inside the thermostat can cause it to malfunction. Fortunately, this is usually an easy fix. In some cases, a malfunctioning thermostat may require adjustment or replacement.
Cleaning the debris that builds up on your filters will aid with the flow of air. When your air filter is clogged, your air handler must work harder to compensate for the blockage of air flow. In addition to driving up your utility bill, the reduced air flow through your heating and cooling system can cause your heat exchanger to overheat and shut off too quickly.
