Service Champions is trusted for professional air conditioning repair services in Mountain View. We often get calls about whether an AC that runs all day must be repaired. If your air conditioner is running constantly, it may be struggling to keep your home cool. It can also be a costly issue. Since the system will use more energy, you’ll pay higher energy bills.
Usually, the AC should run for 15 to 20 minutes and shut off until the thermostat senses more cooling is needed. It may run constantly if it’s excessively hot outside; or, the thermostat may not be set correctly. Otherwise, it’s best to check for issues that can eventually cause the unit to break down. It may need to be repaired if:
If your AC runs all day, check the airflow from the vents. If it’s weak, but the air is cool, the filter may be dirty. Replacing the filter doesn’t require a technician. But a blocked or damaged duct, a frozen evaporator coil, or a faulty motor requires a professional to repair so normal airflow can be restored and your AC can cycle normally.
Small holes in walls or the roof can cause cool air to escape. Your home may never reach the right temperature and the AC will run all the time. Poor insulation can also cause this issue. You may be able to patch small holes. But call a contractor if you suspect a larger hole or insulation needs to be replaced or updated.
A technician can also check for a duct leak or disconnection, which can cause much of the conditioned air to escape. As a result, your AC will run more to compensate. Also, allergens and contaminants from your attic, crawlspace, or outdoors may enter leaky ducts and circulate in your home, decreasing indoor air quality.
Your AC can run all day if it’s low on refrigerant. It will also struggle to cool your home. A bubbling or hissing noise while the unit is running is a sign of a leak. If not fixed, it can cause the compressor to burn out, while exposure to the refrigerant can lead to burns and toxic effects. Schedule air conditioning repair service in Mountain View as soon as possible.
Neglecting to schedule routine maintenance can lead to dirty coils and ducts, airflow issues, and frequent cycling. Or, your AC may not shut off. If so, call for maintenance. Parts may be wearing out if the unit has been running constantly for a long time. Worn parts should be replaced, and various components cleaned and lubricated.
Air conditioners wear out after 10 years or so. Maintenance can extend a unit’s lifespan, but all systems eventually need replacement. Have your AC checked if it runs all day. If an expensive repair is required or the unit has been serviced multiple times in the last year, it should be replaced with a more efficient system.
A contractor will also check if it’s the proper size for your home. Too small a unit will work harder and may not shut down (too big an AC won’t run long enough to lower humidity levels). The size of your ductwork can also be an issue. If ducts struggle to distribute cool air, your AC can be adversely affected.
