Takes about a minute. No obligation.
A contractor quoting a heat pump install in Denton County has to work out what the system will actually be asked to carry, not just what fits the floor plan. 523 severe weather events were recorded in Denton County, Texas between 2015 and 2024. Severe weather at that rate is a standing operating condition, and a unit sized to the catalog minimum rather than to real local load will run longer cycles, strain the compressor sooner, and cost more to replace than a correctly sized unit would have. The sizing conversation happens before anything is ordered.
Existing ductwork is what a contractor has to assess before anything else on a heat pump installation in this county. Half the homes in Denton County, Texas were built in 2003 or earlier (2020-2024 ACS 5-year). Ductwork laid in for a conventional system carries air at different volumes and pressures than a heat pump demands, and whether what is already in the house can handle that difference decides how the job scopes out. Electrical service is a second check: heat pumps draw differently than the equipment they replace, and the panel either supports that or it does not. The unit itself comes after those two answers.
What a Heat Pump Installation Puts in Your Home
The outdoor unit is the piece most homeowners notice first. It sits on a pad outside the house and holds the compressor and the outdoor coil, the two components that do the heaviest work in the system. Inside, the air handler mounts in a utility space, attic, or closet and moves conditioned air through the home.
A refrigerant line set runs between the two units, carrying the working fluid that ties the outdoor and indoor sides together. A thermostat mounts on an interior wall and gives the homeowner control over the whole system, telling both units when to run and at what output.
The drawing shows a typical layout, and a licensed contractor determines what configuration applies to your house.
