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.

Do you deliver?

Bring the model number off the existing equipment and photos of the installation. We will work through it with you at the counter.
