Do you sell complete systems to homeowners?

Yes. We are open to the public and there is no contractor licence required to buy equipment from us. Installing it is a different question - gas, refrigerant and electrical work carry real code and safety requirements.

Can I install this myself?

In Texas the homeowner exemption lets you work on your OWN home. It explicitly does not extend to a friend or a handyman doing it for you. Refrigerant work also requires EPA certification to purchase and handle refrigerant.

How do I know what size I need?

Do not just match what is there - the old unit may have been wrong from the start. Sizing follows from a load calculation on the house, not from square footage rules of thumb, and an oversized system short-cycles and never pulls humidity out.

What is an AHRI match and why does it matter?

The certified performance of the condenser, coil and air handler working together as a set. A condenser is only half a system, and the rating on the box assumes a specific match. Ask for the AHRI certified match number on any quote.
