A/C Repair in Plano, TX

According to the Dallas News, Plano is on track to become the fourth largest city/suburb of Dallas Fort-Worth. It will add 2,000 new homes in 2015 alone. Despite many new homes with new central air systems, breakdowns still occur and can be frequent.

  • 3 Common Problems with new Central A/C Systems

    1. Improper sizing of unit to home: It’s not uncommon for an A/C unit to be too small for a large, new home. Smaller units cost less for developers to install yet often aren’t large enough to cool down a home with high square footage. If you’re A/C is running constantly or it isn’t able to cool down the entire house, you may need a second unit or an upgrade.
    2. Bad wiring. Depending on the home builder and A/C contractor, uncertified technicians could have installed faulty wiring which can trip the circuit breaker and is a fire hazard.
    3. Inadequate Testing. Many new home a/c systems aren’t tested properly in respect to the entire central air system including the a/c unit, air ducts and thermostats. Inadequate testing could lead to an a/c system that is set up for failure in the long run.

    Plano also has a large number of existing homes and businesses. Problems with old A/C units are far different from new units.

    1. Refrigerant leaks. A/C units low on refrigerant could be experiencing a leak. Realize adding more refrigerant does not solve the underlying problem. Contact Lex Air to repair the leak and add more coolant.
    2. A/C Fan or Compressor failure. Common with old systems, these are critical and costly parts that eventually breakdown. A repair could solve the issue, but it be more costly than a full A/C replacement. Lex Air offers flexible financing options and will consult with you on the most economical solution.
    3. Frozen inside air coil. Air coils that freeze are often caused by dirty filters or blocked air ducts. Unless your A/C system is regularly being maintained, repairs and breakdowns for frozen air coils are likely to occur. Learn more about our active maintenance programs.
