A Texas air conditioner can go from occasional use to running for hours a day as soon as the heat settles in. Checking a few things before that first long stretch of hot weather can help you catch small problems while there is still time to address them.
Start with the simple checks
Begin with your air filter. If it is visibly dirty, replace it; otherwise, follow the replacement schedule for your filter and system. A clogged filter restricts airflow, which can make your home less comfortable and put extra strain on the equipment. If you are unsure which filter size to use, check the existing filter or the system documentation.
Next, set your thermostat to cooling and test the system before you need it all day. Give it time to start, then check whether the air coming from the vents feels cool. Listen for new rattling, buzzing, or repeated attempts to start. A brief test is not a substitute for maintenance, but it can reveal a problem early.
Walk through the house and make sure supply vents and return grilles are not blocked by furniture, rugs, or curtains. Keep doors to rooms you use open as appropriate for your home’s airflow. Outside, clear leaves and loose debris from around the outdoor unit. Leave room for air to move around it, and do not open electrical panels or reach inside the equipment.
Check for signs that need attention
Look for water near the indoor unit, ice on refrigerant lines or the equipment, weak airflow, or a system that runs without bringing the temperature down. These are reasons to stop guessing and arrange a professional inspection. If you see ice, turn cooling off and use the fan setting if available while you arrange service; continuing to run a frozen system can make the issue worse.
Some causes are simple, but low cooling can also point to an airflow, drainage, electrical, or refrigerant problem. Refrigerant work and electrical repairs should be left to qualified technicians. Note what you observed and when it happens so you can describe it clearly.
Schedule maintenance before the rush
A tune-up gives a technician a chance to inspect and clean accessible system components, check operation, and flag concerns before peak demand. Bluebonnet Air’s $189-a-year maintenance plan includes two tune-ups and priority scheduling. Scheduling ahead of summer can also make it easier to choose a convenient appointment time.
If the system fails during summer, Bluebonnet Air offers same-day AC repair. Get in touch to ask about a tune-up or describe a cooling problem.
