Properly Inspect Your HVAC System For Costly Problems

Your HVAC system consumes a lot of energy in your home. As such, any problems with operation or design can impact your pocketbook and comfort. Here are some steps you or an HVAC technician can take to fully inspect your HVAC system:

Thermostat Functions

Test thermostat functions in all modes. Listen for unusual noises, such as rattling, knocking and grinding. Rattling noises may indicate loose ductwork, while knocking may be caused by contact between the duct trunk and plenum. Grinding noises are often caused by worn bearings in the blower motor.

First, turn off the thermostat and circuit breaker to your HVAC system. Electrical contacts will then be inspected for snugness and current conditions. Worn electrical contacts can cause your evaporator coil to ice up, which can then impact cooling and wear down parts.

Ductwork System Inspection

Next, open all return grills and check your air filters. Clean or replace as needed. Then, inspect your return ducts for debris, as well as all accessible air ducts for leaks, loose and disjointed seams, damage and insulation.

Your HVAC technician will use sophisticated equipment to detect hidden leaks. Ducts without insulation in the attic or basement should be insulated to prevent heat energy losses. Duct leaks, disjointed ducts and fallen ducts are then sealed with sheet metal screws, mastic sealant and foil-backed tape.

Cooling and Heating Systems

Afterwards, your evaporator coil and heat pump systems are inspected for refrigerant leaks, dirt buildup and mold growth. Your evaporator coil condenses water vapor, which drains away in the drip pan. If you notice musty odors in the home, it could be caused by mold and mildew growth on these components. If this is the case, your drip pan and drain line will be cleaned and treated to prevent mold, bacteria and algae growth.

Next, furnace combustion and venting components are cleaned and inspected for function and safety. Blower ports are oiled, and airflow is measured across the blower and calibrated if necessary.

There are many more system checks and balances that need to be performed to inspect your HVAC system. For the best results, please contact Wolff Mechanical today. We serve residents across Central Arizona.

Our goal is to help educate our customers in the Phoenix Valley area of Arizona about energy and home comfort issues (specific to HVAC systems).
