A Lewisville replacement has to survive the way houses are built there. Attic systems are common. Larger homes often have two units, and only one of them is the complaint. Lake-adjacent humidity plus North Texas heat is the summer story. Winter freezes still reach Denton County.
Lewisville ranges from older homes near Old Town to larger Castle Hills houses and newer sections to the west. Coils that are dirty or oversized short-cycle, drop the temperature, and leave the humidity in the room. People describe it as ‘the air conditioner works but the house feels sticky.’
AC Installation issues we see in Lewisville
Sticky houses at a normal thermostat setting
If the system is short-cycling, the coil never stays cold long enough to pull moisture out. We check sizing, charge, and airflow instead of telling you to set it lower.
One of two systems down
Castle Hills and similar sections often have more than one unit. We identify which system serves the rooms you care about before replacing parts on the healthy one.
What the visit includes
- Existing tonnage versus the house as it is today

How we handle the job
01Survey the house
We look at rooms, glass, attic ducts, and the equipment that is there. Photos are part of the quote.
02Quote options, not a single take-it-or-leave-it number
Good, better, and the duct work each option still needs. Efficiency is explained in plain language, not as a sticker.
03Install and walk through
Commissioning includes airflow, drainage, and a thermostat you know how to use. We haul off the old equipment.

Only if the old tonnage was right. We check the house first. Oversizing is a common Texas mistake and it shows up as short cycling and poor humidity control.
Removal of the old equipment, the new indoor and outdoor match we agreed on, electrical and drainage connections, thermostat setup, commissioning, and a walkthrough. Duct changes are quoted on their own line if you need them.
A straightforward split-system replacement is usually one day. Homes with two systems, difficult access, or duct repairs can take longer, and that is part of the quote.
