Common AC Problems We Fix


AC Electrical Issues

After years of heavy use, electrical components within your air conditioner begin to wear down and lose their effectiveness. When individual parts fail, other parts could malfunction in a chain reaction, which could ultimately impair the entire system.

Common Causes of AC Electrical Problems:

• Aging components
• Loose wires
• Dirty fuses


Outdated & Inefficient Refrigerants

Air conditioners don’t simply add cool air to your home. Refrigerant chemicals work with your system’s evaporator and condenser coils to remove heat and moisture from the air. The old standard refrigerant for air conditioners, R-22, is dwindling in supply and rising in price as the EPA works to phase it out of American AC systems. If your system still runs on R-22, contact Precision Air for air conditioning repair services to help find an appropriate solution.


AC Water Drainage Issues

After refrigerant does its job, water extracted from the air must be drained from the areas surrounding your system. Like any other pipes, AC water drainage pipes should be inspected regularly and repaired as needed. If a clogged pipe is neglected for too long, it could back up your entire plumbing system and cause leaks, flooding, and other serious damage.

We can install ac units with automatic safety switches that bring your system to a halt the moment any AC water drainage backups are detected. If you already have safety switches in your system, it’s important to know how they work. When your system has trouble functioning continuously once turned on, it could be a sign that the drain is backed up and triggering the safety switches.


Ductless Mini Split Repairs

Ductless mini split installations are similar to heat pumps, as they are used for both heating and cooling in your home. We offer professional mini split repairs, performed by technicians who have experience dealing with frustrating issues such as dirty filters, refrigerant leaks, and capacitor problems. Call us.

Feel: If your vent isn’t blowing hot air or is blowing no air at all, it’s time for a repair. Also, if your house has high humidity levels and feels stuffy, it’s a good idea to call for an ac repair.

How to Extend the Life of Your Central Air Conditioner.


1. Clean your outdoor AC unit.
A dirty outdoor compressor struggles to cool your home and makes your energy bill skyrocket. Use a coil cleaner with your garden hose or pressure washer, or we can do it for you.

2. Vacuum your vents.
Central AC systems use intake and return vents. If your vents are blocked, your air conditioner will struggle to keep your place cool. Use a vacuum with a brush or a “Swiffer” type disposable cloth.

3. Get a smart thermostat.
Google Nest “learns what temperatures you like at different times of the day. After a few days of learning, your thermostat will prepare a schedule for you”. It has a phone app so you can adjust the temp from anywhere. It quickly pays for itself in energy savings. It looks cool. We love it. We keep them in-stock and we install.

4. Use blinds, curtains, or glass tint.
The sun gets pretty intense here in the coastal bend. If you let the heat in, your AC has to remove it. You will stay comfy, your AC gets a break, and you save money with a lower electric bill.

5. Join the Comfort Club and get regular ac tune-ups.

When when you join the comfort club, you get exclusive benefits, like free ac maintenance and cleanings, discounts on all air conditioning repairs, and priority ac service visits. Learn more about how regular maintenance can keep your ac running at peak performance.

AC Repair FAQs

How long does a central air conditioning unit last?

– Is your current air conditioner the right size for the job?
Often, builders and homeowners choose based on price, but an undersized HVAC works extra hard to keep your home cool. This shortens its life and drives up your electrical bill.

– Does your current air conditioner get seasonal tune-ups and filter changes?
If both answers are yes, it should last 12-15 years.

What should I do about my frozen AC?


There are two causes for ice on your air conditioner coils; low airflow or a low refrigerant charge.

Low airflow – Low air flow can be related to a very dirty air filter, a dirty blower wheel, or a bad blower motor. These things reduce the amount of air that flows across your coil, causing condensation that freezes instead of draining.

Low refrigerant charge – All AC systems need a proper refrigerant charge to operate efficiently. When new, air conditioners are charged with refrigerant. Since it doesn’t consume any during operation, you must have a leak or faulty installation.

When you see ice on your air conditioning coil, it is serious. Our certified tech can locate the cause of the frozen AC coil and repair it quickly.

What’s wrong with my noisy air conditioner? Can I fix it myself?


First things first, you shouldn’t attempt to fix your air conditioner on your own. Unless you have professional knowledge of HVAC electrical system layouts and the proper meters to test all the working components of your AC, you are putting yourself and your air conditioner at significant risk for harm.

If your AC is making a humming sound, it could be a couple of different things, such as a flipped breaker at the panel box or a blown high-voltage fuse at your outdoor disconnect box. Another (very likely) possibility is that the humming sound is due to a bad start capacitor for both the compressor and the condenser fan motor.

The capacitor’s job is to provide a boost of energy to both the components at start-up, so when the capacitor fails, the fan motor won’t run and the compressor will try to start for a few seconds and hum very loudly, resulting in a noisy air conditioner.

Do you offer emergency ac repair after-hours?


Yes. We are always open and we never charge after-hours fees.  Call or text us from the bottom of this page.
