HVAC Unit Maintenance Checklist and Program

Spring is just around the corner. Now’s the time to consider having your HVAC maintenance check up performed. Properly maintaining your home’s HVAC unit will improve its operating efficiency, lower your monthly energy costs and keep your home comfortable during those hot summer days in Austin. We’ve outlined some basic care items that should be addressed in the spring below:

Exterior HVAC Unit Maintenance

Out of sight, out of mind… We often forget about our exterior AC units until there is an imminent problem. A few simple maintenance tips can eliminate an unexpected failure.

• Remove debris and leaves from the top grille
• Trim brushes, shrubs and trees to allow for at least 2 feet of clearance
• Schedule a semi-annual HVAC preventative maintenance tune-up

This tune up should include: inspection of the following items: the operating pressure and refrigerant charge, temperature drop on cooling coil, condensate drain (primary and secondary), condenser coil (non-chemical cleaning), contactor points.

Interior HVAC Unit Maintenance

• Replace all HVAC unit filters monthly. Dirty filters reduce the efficiency of your unit.
• Inspect air duct for leaks, holes or separated sections
• Schedule an HVAC maintenance tune up

Interior preventative maintenance tune-ups include: cleaning and adjusting pilot, checking combustion, draft and flue, checking for proper ignition, checking relays and checking all wiring connections.

General HVAC Maintenance Checks

During your HVAC maintenance tune up, your technician should also inspect the following items to insure optimal performance:

• Check all operating and safety controls
• Lubricate all moving parts per mfg specs
• Check sequence of operation
• Check filter, change or clean (customer provided)
• Check thermostat
• Check proper voltage and amperage

Overall Home Maintenance

One of the quickest ways to increase energy costs is to have an inefficient home. Homes that lack moisture control or appropriate weatherizing materials will force your HVAC unit to operate more often, thus driving up your energy costs.

• Inspect and reseal windows and doors with weather stripping and caulk to reduce air leaks.
• Maintain your home’s humidity levels at 30% – 50% for optimal conditions.
• Check windows and doors for condensation to ensure that your home doesn’t have too much humidity.
• If your HVAC unit is not operating correctly, it may be time for a replacement. Contact your HVAC professional to discuss your home’s heating and cooling needs and units that will provide optimal comfort for your home.
