McAllen, TX, has always been known for farming due to its year-round warm climate that eliminates the fear of frost-bitten crops with damaged tissues. But while plants may thrive, residents have a hard time dealing with the McAllen heat that is some of the hottest across Texas. According to KLAQ, it’s also in the top 20 hottest cities nationwide, making an AC repair not just about comfort but health and safety. 

At Colair Cooling & Heating, our company with more than 1,600 five-star reviews has over 30 years of experience helping residents and business owners in this and surrounding Texas. So, when your air conditioner starts giving any unusual signs that make you fear its inefficiency and lower cooling capacity, contact our team. 

When Do You Need an AC Repair in McAllen?

When you first purchase a McAllen air conditioning unit, it’s at peak efficiency, cooling your home quickly and effortlessly. Aside from a light humming during cooling cycles due to a functioning blower motor and a clicking thermostat as the HVAC system turns on and off, it’s soundless, odorless, and doesn’t have any visual issues; that is until it does. Yes, unfortunately, these issues arise, and we’ll delve into them below. 

Unusual Sounds Drawing Attention 

Again, clicking is normal, but if the clicking doesn’t cease throughout the cooling cycle, you may have a thermostat sensor issue. Similarly, humming is as expected as popping in the air vents if you have central cooling since the metal chutes expand and contract with changing temperatures. But if the humming turns into a more aggressive buzzing, it may point to electrical problems like a bad relay switch or motor.

Other sounds you should be aware of in McAllen include:

  • Banging or rattling from loose parts knocking into each other
  • Whistling or hissing due to an air or water leak 
  • Grinding from dry moving parts that need lubricating 

Awkward Smells Stinking Up Your Home 

No smells should come from your McAllen unit, but when they do, you’ll need an AC repair. The most common is a mustiness since your unit constantly absorbs warm air and cools it, allowing humidity to develop within. If the drain line clogs and cannot remove this moisture, leaving it to accumulate in the drain pan, fungal growth ensues, contributing to this musty odor. 

You may also have a water leak inside your home, which also causes this foul odor but there are many others to look out for in McAllen:

  • Burning smell from faulty wires or electrical components
  • Rotten egg smell from carcasses stuck inside the condenser unit
  • Old or dusty smell from dirty filters and vents

Other Signs of a Bad AC Unit in McAllen

Sometimes, a bad air conditioner offends the other senses (and your wallet) in the following ways:

  • Warm air blowing due to low refrigerant levels or dirty coils that restrict the heat transfer process
  • Little to no air blowing because of dirty filters or ducts or broken air handlers
  • Cool air blowing but not cooling due to long or short cycling causing hot and cold spots
  • Higher energy bills if your unit has lower efficiency or runs excessively
  • Pooling water or refrigerant from a leaking evaporator unit

How a Stellar Team Helps in McAllen

While some air conditioner repairs just require changing the air filters for optimal airflow or changing the thermostat batteries for the right temperature setting, other fixes are not as simple or straightforward. That’s why you need a five-star team to help you in McAllen especially since May to September sees 90+ degrees, and the months right before and after are not that far off, remaining in the high 80s. 

After receiving a call for repair services, a technician thoroughly inspects the AC unit and listens to your concerns to accurately pinpoint the culprit. Once they make a diagnosis, they explain it to the client and offer repair options and pricing to keep all activity and costs transparent. From there, they use industry-standard tools and decades of know-how to repair the situation before testing the unit.

    The Colair team, Eddie, Joe and others have done an exceptional job. They are servicing both of my AC’s, the one they installed and the one installed by another company. I recently encountered issues with my older unit and they fixed it promptly and discovered it was a design issue with the original install. They came back a couple of days later and fixed the design issue as a more permanent solution.I wish I had called Colair many years ago. They are a great team and I have been very happy with their work. Thanks Colair!

    _I was scheduled to have my home's HVAC unit checked out today since I'm on the Colair Preventative Program that entails preventive maintenance twice a year. Raul Martinez was the technician assigned for the job today. Raul was very thorough and checked out both inside and outside units. After completing all the components, Randy was very informative by informing me of the readings or results of all the components evaluated today. It is great to know that my HVAC is running top notch and one thing less to worry about. Raul did want to make me aware of an issue to be concerned about. Raul pointed out that my inside unit was developing a buildup of what seemed to be mold. Raul called a supervisor, Noah Gonzalez, to come by and further evaluate the issue. Noah was able to explain to me that the duct network needed to be checked for efficiency due to the age of the ducts. Noah went up and discovered several areas that were leaking air generated by the unit. Noah showed me pictures of what he discovered. First, he pointed out that the insulation in the attic was ready to be replaced and then Noah showed me the results of the tests conducted on the duct network. Noah made me aware of the positive and negative reasons in addressing and replacing the duct network and insulation in attic. I had been thinking of replacing the ducts, but now I see the time had come. We discussed price, advantages in replacing now instead of later. Overall, I was very pleased with the inevitable.Thank you Raul Martinez and Moah Gonzalez, and Colair for giving me peace of mind and comfort throughout the year. See you in 6 months Colair!
