Heating and Air Conditioning Services in Sunnyvale, TX

Texas residents know that air conditioning isn’t just a want, it’s a necessity. The scorching heat during Texas summers can make an air conditioner work overtime, which can lead to significant wear and tear if not addressed with preventative maintenance and repairs. Thankfully, with Lyons, you have a team you can rely on for any issues you may experience with your HVAC system. Some of the most common problems our skilled technicians see include:

  • Refrigerant Leak Repairs – Leaking refrigerant can significantly impact how well your AC operates. Our experienced heating and cooling technicians can troubleshoot the leak, repair it, and recharge it to handle the Texas heat.
  • Fixing Drainage Blocks – Drainage blockages contribute to condensation forming within your AC unit. This additional moisture can increase humidity in your home, decreasing efficiency and indoor comfort. The moisture can also have a significant impact on your indoor air quality, and clogged drains can cause your AC to short cycle and shut off unexpectedly.
  • Troubleshooting Frozen Coils – Frozen coils can impact the efficiency of your air conditioning unit. Other underlying issues, such as drain blockages, dirty filters, and low refrigerant levels typically play a role in this malfunction. Our technicians troubleshoot the problem to get your unit back to working order ASAP.
  • Scheduled or Emergency Maintenance – Regularly scheduled or emergency AC maintenance services help to prepare your air conditioning unit for the rigors of the Texas summer heat.
  • New Air Conditioner Installation – Keep your home cool and comfortable with a new AC unit installed by our experienced technicians.

Air conditioning repair is something that will have to happen with almost every system.

  • The system is blowing warm air
  • Loud noises
  • Reduced airflow
  • Weird smells
  • Thermostat not reading accurately
  • Significant increase in utility bills
