Living in South Texas means one thing: you have to be able to handle the heat. With high temperatures that remain in the 80s and 90s for most of the year, the small border town of Mercedes, TX, is no stranger to warm days, and homeowners rely on their air conditioners to stay cool almost year-round. 

Colair, Inc. is here to help you stay comfortable with professional AC maintenance in Mercedes, TX. With almost 40 years of experience serving local homeowners, we know what your cooling system needs for maximum energy efficiency and reliability. When you trust us for preventative maintenance, you can be sure you’ll come home to a cool house after exploring the local shopping centers, drive-in theaters, and other local activities. 

Why You Can’t Skip Air Conditioning Maintenance 

Your air conditioner works hard to maintain a consistently comfortable temperature inside your Mercedes home. Even when you invest in top-of-the-line equipment, near-constant operation can put excessive wear and tear on the internal components. 

When you rely on Colair, Inc. for AC maintenance in Mercedes, TX, you give yourself peace of mind that your cooling system is in peak condition. Other benefits of regular maintenance include.

Better Performance

A tune-up service ensures that every part is working flawlessly so you enjoy trouble-free cooling.

Lower Energy Bills

Air conditioning maintenance ensures that the unit doesn’t have to work too hard to keep your home cool. For example, a clogged air filter restricts airflow, which puts additional strain on the equipment and forces it to use more power. Our AC maintenance in Mercedes, TX, includes filter replacement and more to reduce excess power usage.

Fewer Repairs 

During an air conditioner maintenance visit, our technicians look for signs of trouble within the system and fix minor issues on the spot. You don’t need to worry about small issues getting worse and causing a breakdown that requires repairs, saving you time, money, and aggravation. 

Longer-Lasting Equipment

Taking care of your air conditioner helps it last longer, ensuring you get the most from your investment. With proper maintenance, the average unit can last 15 years or longer.

Preserve Your Warranty 

When you purchase a new air conditioner, it comes with a warranty, but keeping that protection in effect typically requires professional maintenance on a recommended schedule. Colair, Inc.’s AC maintenance in Mercedes, TX, protects your warranty so that, in the event something goes wrong with the equipment, you won’t be responsible for the bill.

The Basics of Preventive Maintenance 

The typical tune-up service for an air conditioner takes an hour or two to complete and includes a comprehensive system inspection, cleaning, and adjustment of critical parts. Colair, Inc. technicians follow a detailed checklist that includes:

  • Inspecting all the critical parts of the unit
  • Conducting physical and electrical tests of key components 
  • Cleaning evaporator and condenser coils, vents, and drain lines  
  • Changing the air filter 
  • Checking the refrigerant levels 
  • Calibrating the thermostat 
  • Adjusting and tightening parts as needed 
  • Lubricating moving parts 

The technician arrives with a fully stocked truck so they can make minor repairs on the spot. You’ll also receive a complete report of the service for your records, which includes any recommendations for additional service or maintenance, such as more frequent air filter replacements. 

Stay Cool With Worry-Free Air Conditioning 

If you can’t remember the last time your air conditioning system had a professional tuneup, schedule a performance check from Colair, Inc. We make AC maintenance in Mercedes, TX, simple, convenient, and affordable, with service from the most highly skilled and experienced technicians in the area. Our A+ rating from the Better Business Bureau, glowing reviews from previous customers, and commitment to fast, friendly service mean you can count on Colair, Inc. to solve your cooling problems.

    Isaiah and Andrew really helped with telling me what’s going on with my system and were very productive and professional
    Response from the owner:Thank you so much for taking the time to leave us a 5 star review!
    I just want to thank Colair for the kind staff they have. This past Friday, Carlos Castillo came to perform maintenance on our unit. He was very professional both in his treatment of me and in his work. He was very patient in answering each of my questions and also made some recommendations. One thing I want to highlight, because I pay close attention to details, is that he used disposable shoe covers, which he removed from his shoes every time he left the house and put back on when he came back in. This is very important to us since the pandemic; at home, we remove our shoes before entering. He even took the trash away in his vehicle. Thank you, Carlos. Despite being so young, you are very mature, respectful, professional, and, above all, responsible. I also appreciate that, even though it was a Friday afternoon, you took the time to do your job and make sure I was happy and satisfied. God bless you!
