Heat Pump Replacement in Lewisville, TX
Heat pump replacement means removing an existing heat pump and air handler and installing correctly matched new equipment. Unlike straight cooling systems, heat pump replacements require matching outdoor unit, indoor coil, and air handler as a system — mismatched components reduce efficiency and can cause premature failures. We also check refrigerant line sets for compatibility with current refrigerant types, since older line sets may need flushing or replacement. The refrigerant transition to R-454B makes equipment selection more important right now than it has been in years.

When to Call
When You Need Heat Pump Replacement
- Your Lewisville home heat pump compressor has failed and the unit is over twelve years old.
- Repeated repairs over two seasons have cost more than a replacement would have.
- Your heat pump uses R-22 refrigerant and parts are no longer practically available.
- An energy audit shows your aging heat pump is running at well below its rated efficiency.
How It Works
Our Process for Heat Pump Replacement
- 1
System Compatibility Review
We check existing line set size, air handler compatibility, and electrical supply before specifying replacement equipment.
- 2
Equipment Matching
Outdoor unit and indoor coil are selected as a matched set — not mixed from different efficiency tiers or manufacturers.
- 3
Removal and Installation
Existing equipment is recovered and removed. New system is installed, line set is flushed or replaced as needed, and system is charged.
- 4
Commissioning
We verify operation in both heating and cooling modes, check refrigerant charge against manufacturer specs, and confirm defrost function.
Lewisville Context
Why this matters in Lewisville
Lewisville's climate puts heat pumps in cooling mode for seven or more months a year, which means compressor hours accumulate faster than in northern climates. That accelerates the timeline to replacement compared to what manufacturers' general lifespan estimates suggest.
Straight Talk
About pricing & scope
Air handler replacement is sometimes required alongside the outdoor unit for refrigerant compatibility or efficiency rating reasons — we identify that during the assessment. Line set condition and electrical panel capacity can also affect total scope.
