Why Heat Pump (Not Gas Furnace + AC) for Garland Homes

Garland is predominantly 1960s-1980s suburban housing in the 75040-75044 ZIP corridor. Most homes are running second- or third-generation HVAC equipment — typically a 2005-2015 vintage single-stage gas furnace + AC pair. Those systems are now in the replacement window.

The conventional replacement path is another gas furnace + AC pair. That's no longer the right answer for most Garland homes. Three reasons:

1. Heating loads have collapsed. Many Garland homes have had insulation upgrades, window replacements, and attic radiant barriers added during prior renovations. The current heating load is meaningfully smaller than the original equipment was sized for.

2. Inverter heat pump efficiency exceeds gas furnace economics. Modern Mitsubishi Hyper-Heat (H2i) heat pumps deliver coefficient-of-performance values above 3.0 across the typical Dallas heating-season temperature range. Combined with rising natural gas pricing volatility since 2021, the operating cost case for heat pump versus gas furnace is consistently favorable for heat pumps in Garland.

3. Heat pumps simplify the system. Gas furnace + AC pair = two pieces of equipment, gas line, gas meter, combustion appliance. Heat pump = one piece of equipment, all-electric, no gas service required.

The Humidity Connection

Garland homes have a specific humidity dynamic that's gotten worse over the past two decades. Three factors compound:

Rising DFW outdoor humidity. Outdoor dew points have risen measurably across the metro. The cooling system that handled humidity adequately in 2010 is now fighting wetter outdoor air.

Aging ductwork in unconditioned attic space. Most Garland homes have original ductwork from construction running through attic space that exceeds 130°F in summer. Joints have separated, return-side leakage pulls humid attic air directly into the system, and 25-35% of conditioned air is lost on the supply side.

Single-stage equipment that short-cycles. Aging single-stage AC systems short-cycle as efficiency degrades. Cycle times shorten as the system ages, and the system stops running long enough to dehumidify properly.

The result is a Garland home where the thermostat reads 72°F but indoor RH is 60-65%. The home doesn't feel conditioned even when the AC is running.

The inverter heat pump fix: Mitsubishi inverter compressors modulate output continuously, running at the actual building load in real time. Continuous running = continuous dehumidification. Pair the inverter equipment with proper ductwork sealing during the replacement, and the humidity problem resolves within the first week of operation.

What Heat Pump Replacement Looks Like in Garland

Mitsubishi P-Series ducted heat pump. For most Garland homes where the original ductwork is salvageable (or salvageable with sealing), Mitsubishi P-Series ducted heat pump is the standard replacement. Inverter modulation, R-32 refrigerant, Hyper-Heat (H2i) cold-climate capability, 12-year Diamond Dealer warranty.

Mitsubishi SVZ-KP slim-duct heat pump. For Garland homes with constrained ductwork space.

Mitsubishi SUZ-KA + PVA air handler. For full system replacements when the existing air handler is also at end of life.

Multi-zone ductless for chronic problem rooms. For Garland homes with chronic temperature differentials, a Mitsubishi MXZ multi-zone supplemental system addresses problem zones independently of the central replacement.

Equipment sizing. Manual J load calculation on the actual home — accounting for current envelope, current insulation, current solar exposure — produces the right capacity. Most renovated Garland homes calculate to 2.5-3.5 tons (smaller than the original equipment was sized for).

R-32 Refrigerant in Current Garland Replacements

Every Mitsubishi heat pump installed today uses R-32 refrigerant — the EPA AIM Act compliant refrigerant for residential equipment manufactured after January 1, 2025. R-32 has a global warming potential of 675, roughly 68 percent lower than R-410A's 2,088. R-32 is classified A2L — mildly flammable — requiring A2L-certified installation. Truficient technicians are A2L-certified for R-32 systems.

Why Truficient for Garland Heat Pump Replacement

Garland heat pump replacement is an engineering project. The original equipment was sized using rule-of-thumb tonnage for the construction era, and the actual envelope is meaningfully different after decades of upgrades. Replacement equipment needs to be right-sized to the current envelope.

Eric, Truficient's owner and the engineer behind every install, runs every Garland assessment personally. Manual J load calculations account for the building envelope as it actually exists today.
