Look at the filter about once a month, especially when the system runs often. Replace it according to the filter label and your equipment instructions, or sooner if it is visibly dirty. Pets, dust, and heavy use can mean more frequent changes. Use the correct size and airflow direction; do not run the system without a filter.

Choose a comfortable temperature you can maintain consistently rather than making extreme changes to cool the home faster. In cooling mode, set the fan to Auto so it stops when the cooling cycle ends; leaving it On can circulate humid air. If you have a heat pump, follow its thermostat instructions before making large heating changes.

Keep supply vents and return grilles clear of rugs, furniture, curtains, and storage. A blocked return can restrict airflow through the whole system. Avoid closing many vents to redirect air; if a room stays uncomfortable with vents open, ask a professional to evaluate airflow.

Keep leaves, grass clippings, and stored items away from the outdoor unit. Follow the clearance specified by the equipment manufacturer; requirements vary by model. You can gently remove loose debris from the surrounding area, but do not open the cabinet, reach into the fan, or spray electrical components.

Compare the bill with similar weather and usage, then check simple things: the thermostat schedule, a dirty filter, blocked grilles, and doors or windows left open. A change in rates or unusually hot or cold weather can also affect the total. If the system runs much longer than usual or comfort has changed, schedule an evaluation rather than guessing at a repair.

Check that the thermostat is set correctly, the filter is not clogged, and vents and returns are open and unobstructed. If airflow remains weak, switch the system off and arrange service. A blower, duct, or coil issue needs professional diagnosis; do not open electrical panels to investigate.

Turn cooling off and call a qualified professional. Ice can form when airflow is restricted or for other reasons that need diagnosis. Do not chip off ice, pour hot water on the coil, or keep restarting cooling. If you can safely do so, note whether the filter is dirty and tell the technician what you observed.

A small amount of condensation belongs in the drain system, not on your floor or ceiling. If water is leaking or collecting, turn cooling off to limit further damage and arrange service. Keep clear of wet electrical equipment. Do not pour drain chemicals into the system; the cause may be a clog, damaged drain, or something else.

On cool, damp days a heat pump may briefly enter defrost mode. You might see steam from the outdoor unit and hear a change in sound; this can be normal. If ice keeps building up, heat is not returning, or the unit stops working, request service. Never chip ice off the outdoor coil.

Auxiliary heat can come on during very cold weather or when the heat pump needs help reaching the set temperature. It may also operate during defrost. If it stays on frequently in mild weather, check the thermostat settings and filter, then have a professional evaluate the system. Avoid repeated large thermostat changes.

A new grinding, screeching, banging, or persistent rattling sound is worth a service call. Note when it happens and whether heating or cooling is running. If a noise is sudden and severe, turn the system off and arrange an inspection. Do not remove panels or put hands near moving parts.

Leave the building immediately and call emergency services or your gas utility from outside. Do not use switches, a thermostat, phones inside, flames, or any appliance while leaving. Do not go back inside until emergency responders or the gas utility say it is safe. A carbon monoxide alarm needs the same immediate response even if you cannot smell anything.

We recommend twice-yearly maintenance: once in spring before cooling season and once in fall before heating season. San Antonio's hot, humid climate and frequent use make regular maintenance crucial for efficiency, reliability, and extending your system's lifespan. Our maintenance plans include priority scheduling and discounts. A technician can inspect components and test operation safely. Between visits, homeowner care is limited to accessible filters, clear vents, thermostat settings, and keeping the outdoor area tidy.

Confirm that the thermostat is in heat mode, the requested temperature is above the room temperature, and vents and returns are clear. Check the filter if it is accessible. If the house still does not warm up, arrange a professional evaluation. Do not repeatedly reset breakers or bypass any safety controls.

Request an evaluation when comfort drops, the system cycles unusually, airflow changes, you notice a leak, or a new sound or smell appears. Write down what happened and when it started; this helps with diagnosis. Avoid working on live electrical parts, refrigerant lines, or gas components yourself. A technician can explain whether repair or another option makes sense.
