Check And Replace Air Filters

The air filters in your HVAC system are responsible for clearing the air of dust and other pollutants. Over time, they can become clogged with dirt and debris, reducing their effectiveness. Depending on usage, check your air filters frequently, and change them every one to three months.

Inspect And Clean Coils

Your HVAC system has evaporator and condenser coils requiring regular cleaning to function correctly. Your system's efficiency might be reduced by dirty coils, which makes it work harder and raises your energy costs. Inspect and clean the coils at least once a year to ensure optimal performance.

Check Electrical Connections

Loose or malfunctioning electrical connections can cause your HVAC system to malfunction or pose a safety hazard. Make sure to check all electrical connections and tighten any loose wires. If you spot any signs of damage, such as frayed wires or burnt connectors, contact Holy City Heating and Air, LLC, for repairs.

Test Thermostat Calibration

A thermostat that's not calibrated correctly can cause your HVAC system to run inefficiently. Test your thermostat calibration by setting it to a desired temperature and monitoring the room temperature. If there's a significant discrepancy, it may be time to replace your thermostat.

Check Refrigerant Levels

Low refrigerant levels can cause your HVAC unit to work harder and reduce lifespan. Inspect refrigerant levels regularly, and refill as needed. If you notice that your system requires frequent refills, a leak may need to be repaired.

Clean Blower Components

The blower motor and wheel in your HVAC system can become dirty over time, reducing efficiency. Ensure to clean these components at least once a year to ensure proper airflow. A dirty blower wheel can also lead to poor indoor air quality, so it's essential to keep it clean.

Inspect Gas Connections

If you have a gas-powered furnace or boiler, it's essential to inspect the gas connections regularly. Look for signs of corrosion or leaks, and tighten any loose fittings. If you smell gas or suspect a leak, immediately evacuate your home and contact Holy City Heating and Air, LLC.

Check Condensate Drain

HVAC systems have a condensate drain that removes moisture from the air. Over time, this drain can become blocked with dirt and debris, causing water to back up and potentially damage your system. Inspect and clean the drain at least once a year to ensure proper function.

Perform System Test Run

After performing all the tasks on this checklist, performing a test run of your HVAC system is essential. This can help identify any problems that need to be addressed before the start of the season. Listen for any unusual sounds and monitor the temperature and airflow.
