Without a functioning air conditioner, your home or business turns into a hot box where relaxing is next to impossible. We provide prompt AC services to restore your home to a comfortable temperature quickly. 

AC Repair

You may need an AC repair if your unit has begun making strange noises, you notice odd smells, the thermostat temperature lingers a few degrees higher than you programmed it, or the unit stops turning on entirely. Our HVAC company arrives at AC repair jobs with all the equipment we may need to resolve the issue.

It may be time for a new AC installation if your AC must run constantly to cool your home, your system is more than 20 years old, or your energy bills are unreasonably high. Allow our licensed and insured contractors to install a new unit that suits your budget and energy goals. We’ll haul away the old unit and ensure the new one performs optimally before leaving. 

AC Maintenance

Annual AC maintenance keeps your air conditioner in the best shape to continue cooling your home or business long-term. We complete a thorough checklist of services as part of our AC maintenance program. Rest assured that your AC will perform reliably for the year after we have given it a once-over.

    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!
