Won’t Turn On
If your AC system doesn't turn on at all, you won’t need us to tell you that there's a problem—but what exactly is causing it? Quite often, your cooling unit isn't actually to blame. It could be that a circuit breaker has tripped in your electrical panel, or there is faulty electrical wiring. It's also possible that the system became overheated because it was not getting adequate ventilation, and it shut itself off to avoid a disaster.
Before you call our HVAC professionals, check your circuit breaker box and give it a reset, then take a look at your outdoor condenser unit and make sure there are no plants, trash, or anything else nearby that could be blocking its air intake. If that doesn't solve the issue, give us a call for AC repair. McKinney, TX residents can count on us, we will send out our HVAC system repair expert to diagnose the issue and get it turned back on.
Unusual Noises
A forced-air system is never going to be completely silent because you'll be able to hear the sound of moving air when it’s on and probably a quiet humming noise near the actual unit. But if you're hearing strange sounds such as screeching, squealing, buzzing, or grinding, there's definitely a problem that needs AC repair. McKinney, TX HVAC experts will tell you that there are a few possibilities for what's making the noise, but the most likely issue is that the fan belt has worn out and needs to be replaced. The best way to deal with that is to turn the unit off and call Aire Serv for help. If you keep the system running and the fan belt breaks before we get to it, the replacement will end up being more costly and time-consuming.
Leaking Fluid
If you notice fluid leaking from any part of your system, such as excess moisture under or near an indoor unit, it is likely water. That's a serious issue because excess moisture can do a lot of damage to your house in a short amount of time. Water leakage is often related to a clogged condensate drain line. However, it's also possible that the liquid is refrigerant. This toxic substance can cause serious health problems if it is touched or inhaled, so if you suspect a refrigerant leak, you should stay away from it, open windows in that area, and call our service professionals right away for AC repair.
McKinney, TX residents can rely on us to check it out, confirm what the liquid is and where it's coming from, and then get it repaired so they can rest easily. We'll also check your refrigerant levels to make sure the system has an adequate amount of refrigerant to work with.
Blowing Warm Air
One of the most aggravating issues homeowners can experience is when their air conditioner is on, but there's only warm air coming out of the air ducts. Sometimes this is just a simple error that is easily corrected, so it makes sense to double-check and ensure that the system is in cooling mode. If it is, try turning it down a few degrees and see if anything changes. But if you don't have any luck with that, it's possible the problem is a frozen evaporator coil that is malfunctioning because of an issue such as low refrigerant levels or poor circulation. When you need experts to get it unfrozen and restored to full function, you can trust us for air conditioning repair in McKinney, TX.
