Tech Tips

HVAC Systems have a lot of moving parts. Parts that are more likely to fail when the demand (load) is the highest. The purpose of preventative maintenance is to prevent problems and part failure through the cooling season. Having a preventative maintenance performed on your HVAC System every Spring can save money in service calls with a diagnostic charge. Making sure your system is operating properly can also save you money on your monthly power bill.

The preventative maintenance checklist includes:

• Check and tighten all electrical connections/terminals
• Check capacitors at indoor and outdoor units
• Replace filter(s)
• Check amp draw on motors and compressor
• Check refrigerant charge
• Clear condensate lines
• Check safety switches
• Clean condenser coils
• Check condition and tightness of the duct system

Every HVAC System has at least one air filter. Most systems use the standard 1″ filter. We recommend you change your air filters monthly. Some pleated filters can be changed every three or six months but it is wise to check your filter often. Any dirt that gets past the air filter can cause harm to the system. It can increase operating costs and make the system operate inefficiently. Dirty air filters can be the cause of all sorts of problems with your system. They can have the following effects:

• Reduce air flow
• Allow dirt to get into the ductwork
• Block the coil with dirt
• Block the blower fan with dirt
• Allows dirt to accumulate on the fan blades

It is very important to keep your outdoor unit clear of any dirt and debris. This will help the unit operate efficiently. If the airflow is restricted, the unit will not work properly. This could also cause damage to parts and reduce the life span of the unit. We suggest that you keep at least 2′ around the unit clear and at least 3′ above the unit clear.
