Heat Pump Installation & Repair

Heat Pump Services in Killeen, Temple & Central Texas

Texas Temp Masters specializes in heat pump installation, repair, and maintenance throughout Killeen, Temple, Waco, Harker Heights, and all of Central Texas. Heat pumps are one of the best HVAC choices for the Texas climate because they provide both heating and cooling from a single system while using significantly less energy than traditional furnace and AC combinations.

Central Texas is ideal heat pump territory. Our mild winters (average lows in the 30s-40s) and long, hot summers mean a heat pump can operate at peak efficiency for most of the year. For homeowners looking to lower energy bills, reduce their carbon footprint, or replace an aging HVAC system, a heat pump is often the smartest investment.

Why Heat Pumps Are Ideal for Central Texas

Heat pumps work by transferring heat rather than generating it, which makes them dramatically more efficient than traditional heating systems. Here is why they are particularly well-suited for our region:

Climate Match:

• Central Texas average winter lows (30s-40s) are well within the efficient operating range of modern heat pumps
• Heat pumps are most efficient above 25-30 degrees — which covers 95%+ of our winter temperatures
• They provide cooling in summer just like a standard air conditioner
• Dual-fuel/hybrid systems pair a heat pump with a gas furnace for the coldest nights, giving you the best of both worlds

Energy Efficiency:

• Heat pumps deliver up to 300% efficiency (3 units of heat for every 1 unit of electricity)
• Compare that to a gas furnace at 80-98% efficiency or electric resistance heat at 100% efficiency
• In Central Texas, a heat pump can reduce heating costs by 30-50% compared to a gas furnace
• Modern variable-speed heat pumps achieve SEER2 ratings of 20+ for cooling and HSPF2 ratings of 10+ for heating
• Learn about SEER vs SEER2 ratings

Cost Savings:

• Lower monthly utility bills year-round
• One system for both heating and cooling means lower maintenance costs
• Federal tax credits up to $2,000 for qualifying heat pump installations
• Utility company rebates may also be available

Environmental Benefits:

• No on-site fossil fuel combustion (all-electric)
• Lower carbon emissions than gas furnace systems
• Uses electricity, which increasingly comes from renewable sources in Texas
• No carbon monoxide risk from the heating system

Heat Pump Repair Services

When your heat pump is not heating or cooling properly, Texas Temp Masters provides expert diagnosis and repair. Our technicians are trained on all heat pump brands and configurations.

Common Heat Pump Repairs:

• Refrigerant leak detection and repair — Heat pumps rely on proper refrigerant charge for both heating and cooling. A leak reduces performance in both modes. Refrigerant cost tool.
• Reversing valve replacement — The reversing valve switches the system between heating and cooling modes. When it fails, your heat pump may get stuck in one mode.
• Defrost system troubleshooting — Heat pumps need to defrost the outdoor coil periodically during winter. A failed defrost cycle leads to ice buildup that blocks airflow.
• Compressor repair and replacement — The compressor circulates refrigerant through the system. Compressor failure requires professional diagnosis to determine if repair or replacement is the better option.
• Electrical control repairs — Control boards, relays, capacitors, and contactors can all fail, especially during extreme temperatures.
• Thermostat programming and calibration — Heat pump thermostats are more complex than standard thermostats because they manage heating, cooling, auxiliary heat, and defrost cycles. Thermostat troubleshooting.
• Fan motor replacement — Both indoor blower motors and outdoor condenser fan motors.
• Condensate drain cleaning — Prevents water damage from clogged drain lines.

Heat Pump Repair Costs in Central Texas:

Repair Type	Typical Cost Range
Diagnostic / service call	$75 - $150
Capacitor replacement	$150 - $350
Contactor replacement	$150 - $350

Common Heat Pump Problems and Troubleshooting

Heat pump not heating:

• Check thermostat settings — make sure it is set to “heat” mode, not “cool” or “off”
• Check air filter — a clogged filter restricts airflow and reduces heating capacity
• Check outdoor unit — make sure it is not blocked by debris, ice, or snow
• If the outdoor unit is covered in ice, the defrost cycle may have failed. Call for service.
• Low refrigerant reduces heating capacity. If your heat pump is blowing lukewarm air, a refrigerant leak is a likely cause.

Heat pump not cooling:

• Functions like a standard AC in cooling mode. Check thermostat, air filter, and circuit breakers.
• AC not blowing cold air troubleshooting

Ice buildup on outdoor unit:

• Light frost on the outdoor unit in winter is normal — the defrost cycle handles it
• Heavy ice that covers the entire unit indicates a defrost system failure
• Blocked airflow from leaves, grass, or debris can also cause ice buildup
• Do NOT try to chip ice off the unit — you may damage the coils. Call for professional service.

Heat pump running constantly:

• During extreme temperatures (below 30 degrees or above 100 degrees), running constantly can be normal
• If it runs constantly in moderate weather, check the air filter and thermostat settings
• A refrigerant leak, dirty coils, or undersized system can also cause constant running

Auxiliary/emergency heat running too much:

• “Aux heat” or “EM heat” on your thermostat means the backup electric heat strips are running
• This is normal during defrost cycles and very cold weather
• If aux heat runs frequently in mild weather (above 40 degrees), your heat pump may have a problem — call for service
• Running on auxiliary heat constantly is very expensive (3-4x the cost of heat pump operation)

Heat Pump Maintenance

Regular maintenance keeps your heat pump running efficiently and extends its lifespan. Because heat pumps run year-round (heating in winter, cooling in summer), bi-annual maintenance is recommended.

Spring Maintenance (Before Cooling Season):

• Clean condenser and evaporator coils
• Check refrigerant levels and pressures
• Inspect and tighten electrical connections
• Test compressor and fan motor performance
• Clean condensate drain line
• Replace air filter
• Calibrate thermostat

Fall Maintenance (Before Heating Season):

• Test heating mode and reversing valve operation
• Check defrost system function
• Inspect auxiliary/emergency heat operation
• Test safety controls and sensors
• Check refrigerant charge
• Inspect outdoor unit for damage or debris
• Replace air filter

Heat Pump Lifespan: How Long Does a Heat Pump Last?

A well-maintained heat pump typically lasts 12-15 years. Because heat pumps run year-round (unlike an AC that only runs in summer or a furnace that only runs in winter), they accumulate more operating hours and may have a shorter lifespan than standalone systems.

Factors that affect heat pump lifespan:

• Maintenance — Annual professional maintenance can add 3-5 years to your system’s life
• Climate demands — Central Texas heat puts significant stress on cooling components
• Installation quality — Proper sizing and installation are critical for longevity
• Usage patterns — Constant temperature settings are easier on the system than large temperature swings

Frequently Asked Questions About Heat Pumps

How much does a heat pump cost to install in Texas?

A standard split-system heat pump installation in Central Texas typically costs $5,000-$9,000, depending on the system size, efficiency rating, and any ductwork modifications needed. High-efficiency variable-speed systems range from $7,000-$14,000. Ductless mini-split heat pumps cost $3,000-$5,500 for a single zone and $6,000-$15,000 for multi-zone systems. Federal tax credits of up to $2,000 can significantly reduce your net cost. Read our heat pump cost guide.

Is a heat pump worth it in Texas?

Yes. Central Texas is one of the best climates in the country for heat pump efficiency. Our mild winters rarely drop below the heat pump’s efficient operating range, and a heat pump provides cooling in summer just like a standard AC. Homeowners who switch from an older gas furnace and AC to a heat pump typically see 20-40% lower annual energy costs. The combination of energy savings and available tax credits makes heat pumps a strong investment for Texas homeowners.

How long does a heat pump last?

A well-maintained heat pump typically lasts 12-15 years. With consistent professional maintenance (bi-annual tune-ups), some systems last 18-20 years. Without maintenance, lifespan can drop to 8-10 years. Read our complete heat pump lifespan guide.

What is the difference between a heat pump and an air conditioner?

A heat pump and an air conditioner use the same technology to cool your home — both use refrigerant to absorb heat from indoor air and release it outdoors. The difference is that a heat pump includes a reversing valve that allows it to reverse the process in winter, absorbing heat from outdoor air and releasing it inside. This means a heat pump provides both heating and cooling from one system. Heat pump vs AC: detailed comparison.

Is a heat pump better than a furnace in Texas?

For most Central Texas homes, a heat pump provides lower operating costs than a gas furnace because of our mild winters. A heat pump runs at 200-300% efficiency in typical Killeen winter temperatures, while the most efficient gas furnace maxes out at 98%. The main advantage of a gas furnace is faster, warmer air delivery during the coldest days. A dual-fuel system (heat pump + gas furnace backup) gives you the best of both worlds. Heat pump vs furnace for Texas.

What is auxiliary heat on my thermostat?

Auxiliary heat (or “aux heat”) is the backup electric resistance heat strips built into your heat pump system. They activate automatically when the heat pump alone cannot meet demand — typically during very cold weather (below 30-35 degrees) or during defrost cycles. Auxiliary heat is much more expensive to run (3-4x the cost), so if your thermostat shows “aux heat” running in mild weather (above 40 degrees), it usually means your heat pump has a problem that needs professional attention.

How much does heat pump repair cost?

Most heat pump repairs in Central Texas cost between $150 and $700. Common repairs like capacitor replacement run $150-$350. Reversing valve replacement, which is unique to heat pumps, costs $400-$900. Compressor replacement is the most expensive repair at $1,200-$2,500. We provide upfront pricing before starting any work.

Do heat pumps work in cold weather?

Modern heat pumps work effectively down to about 25-30 degrees, which covers the vast majority of Central Texas winter temperatures. Some newer cold-climate heat pumps can heat efficiently down to 0 degrees or below. For the rare occasions when temperatures drop below your heat pump’s efficient range, auxiliary heat strips or a gas furnace backup (dual-fuel system) provide supplemental heating.
