Top signs you may need an AC repair include:

  • Moisture pooling around your unit
  • Frozen AC coils
  • Unpleasant odors wafting out of your air conditioner or ductwork

Trusted AC Installations

Bad installation is at the root of many air conditioning problems. An oversized unit may switch on and off too often, allowing a high level of humidity to remain in your home. On the other hand, an undersized unit has to work too hard to cool your space on hot days, shortening system life expectancy and driving up your cooling costs. Bad duct design can also cause some rooms in your house to be too hot, while leaving others too cool.

A quality air conditioner is a significant investment, so it pays to choose an AC contractor with years of experience and a stellar local reputation. Fortunately, your satisfaction is our top priority at Lex Air Conditioning and Heating, and our goal is to do the job right the first time. Our Carrollton HVAC installation technicians are highly trained to install a brand new, energy-efficient AC system in your home so you can enjoy reliable cooling relief for years to come. And with industry-leading makes and models from all the top brands on the market, you’ll never have to worry about getting the best when you hire Lex. Whether you are looking to replace your old AC unit, or are moving to a new home and need trustworthy AC installation, our team has the equipment your house deserves.

Preventive AC Maintenance

The two most important things a homeowner can do to protect their air conditioner are actually very simple. First, change the air filter regularly. Second, schedule an annual maintenance check, preferably during the spring. The beauty of performing regular, routine air conditioning maintenance is that it gives you the chance to catch small issues before they can become big problems, so your system works better and lasts longer.

At Lex Air Conditioning and Heating, our certified service technicians are proud to offer comprehensive AC maintenance in Carrollton. Our team follows a thorough checklist as they assess the condition of your unit, find any worn parts, clean away dirt, check the drains, and tighten loose connections. Remember, a little TLC could prevent an inconvenient breakdown, saving you money on repair and replacement costs. On top of this, annual tune-ups and maintenance help your air conditioner become more energy-efficient, so you can even reduce your cooling bills!
