Signs You Need Heat Pump Service (No Heat, Short Cycling, Ice, Odors)
No heat or cooling
The most obvious sign—your system won't produce warm or cool air when needed.
Short cycling or constant running
Your heat pump turns on and off frequently or runs non-stop without reaching set temperature.
Ice on outdoor unit or lines
Ice buildup on your coil or refrigerant lines indicates airflow problems or low refrigerant.
Strange noises or odors
Grinding, squealing, or burning smells mean components like the blower motor (ECM) may be failing.
High energy bills or poor airflow
Sudden bill increases or weak airflow (CFM) suggest efficiency problems.
Thermostat not responding
Your smart thermostat settings don't match actual room temperature.
Aux heat or emergency heat running too often
Frequent use of heat strips (auxiliary heat) or emergency heat means your heat pump isn't working properly.
Common Heat Pump Problems We Fix
Low Refrigerant (R‑410A/R‑22), Leaks & Leak Detection
Whether your system uses R-410A refrigerant or older R-22, leaks reduce efficiency and cooling power. Because R‑22 is phased out and scarce, repairs involving refrigerant can be costly; we'll discuss replacement vs. repair based on leak severity and long‑term costs.
Compressor, Reversing Valve & Defrost Control Board
The compressor and reversing valve are critical components. When they fail, your system can't switch between heating and cooling. The defrost control board prevents ice buildup. When it fails, efficiency drops dramatically.
Dirty Coils, Clogged Filters & Airflow/Static Pressure
Dust and debris block heat transfer, forcing your system to work harder. Problems affect static pressure and airflow (CFM).
Electrical: Capacitors, Contactors, Relays
These electrical components (capacitor, contactor) wear out over time and cause system failures.
TXV/Expansion Valve & Condensate Drain/Float Switch
The expansion valve (TXV) regulates refrigerant flow. Blocked condensate drain and float switch issues cause water damage and system shutdowns.
Repair vs. Replacement in Dallas: Age, SEER2/HSPF2, Cost
System age, SEER/SEER2 rating, HSPF/HSPF2, and repair history
Systems over 10 years old with low SEER Rating (Seasonal Energy Efficiency Ratio) often cost more to repair than replace. SEER2 and HSPF2 are updated efficiency ratings that better reflect real‑world ductwork and static pressure. Higher numbers mean lower operating costs and improved comfort in Dallas' hot summers.
Compressor and coil condition
Major component failures like compressor or coil damage usually mean replacement makes more sense.
Refrigerant type (R-22, R-410A, R-454B) and availability
R-22 systems face expensive repairs due to refrigerant scarcity. R-454B primarily offers lower global warming potential (A2L class) compared to R‑410A; we follow manufacturer and code requirements for safe handling and ventilation.
Cost to repair vs. long-term efficiency gains
We calculate whether repair costs justify keeping older, less efficient equipment.
Rule-of-50% and remaining lifespan considerations
If repairs exceed 50% of replacement cost, we typically recommend upgrading.

New pad/disconnect, line set flush or replacement
Drain pan with float switch and code‑compliant condensate routing
City of Dallas permit and passed inspection documentation
Thermostat setup and homeowner walkthrough
Manual J/S/D, Right‑Sizing & Duct Design
Proper sizing starts with Manual J, Manual S, Manual D calculations for your specific home. We match equipment to your home's exact needs and ductwork capacity.
AHRI‑Matched Systems & ENERGY STAR Options
We install AHRI matched system components that qualify for ENERGY STAR qualification when possible. We provide the AHRI certificate number for your records—often required for Oncor rebates and federal 25C tax credit documentation.
Line Set, Electrical Disconnect & Commissioning
Your line set and electrical disconnect are checked and upgraded if needed. Our team follows manufacturer specifications exactly for warranty protection.
City of Dallas Permits & Inspections
We handle all permit applications and ensure code compliance. We pull the mechanical permit, schedule City of Dallas inspections, and provide all close‑out documents so your installation passes the first time.
Ductless Mini‑Split Repair & Install (Inverter, Single/Multi‑Zone)
Single- and multi‑zone ductless options
Mini-split (ductless heat pump) systems provide targeted comfort without ductwork.
Inverter (variable-speed) outdoor units for efficiency
Inverter compressor (variable-speed) technology saves energy by adjusting output to match demand.
Best uses: additions, garages, bonus rooms, and spot cooling/heating
Perfect for spaces where traditional ducted systems aren't practical.
Dual‑Fuel (Gas + Heat Pump) Systems & Smart Thermostats
When dual‑fuel makes sense in Dallas' mild winters
Dual-fuel system combinations use heat pumps for mild weather and gas for extreme cold.
Smart thermostat control for fuel-switching
Modern thermostats automatically choose the most efficient fuel source.
Compatibility with existing furnaces
We can add heat pumps to work with your current gas furnace.
2023-2025 Efficiency Standards (SEER2/HSPF2) & Comfort
What SEER2 and HSPF2 mean for efficiency and savings
New testing standards provide more accurate efficiency ratings for real-world conditions. SEER2 and HSPF2 are updated efficiency ratings that better reflect real‑world ductwork and static pressure. Higher numbers mean lower operating costs and improved comfort in Dallas' hot summers.
North Texas climate considerations for sizing and comfort
Dallas's hot summers and mild winters affect equipment selection.
ENERGY STAR qualifications and utility bill impact
High-efficiency systems can cut cooling costs by 20-40%.
Refrigerants: R‑22 Phaseout, R‑410A & R‑454B (EPA Rules)
R‑22 availability and why it impacts repair decisions
R-22 prices have skyrocketed due to the EPA phaseout. Because R‑22 is phased out and scarce, repairs involving refrigerant can be costly; we'll discuss replacement vs. repair based on leak severity and long‑term costs.
R‑410A vs. R‑454B performance and service differences
R‑454B primarily offers lower global warming potential (A2L class) compared to R‑410A; we follow manufacturer and code requirements for safe handling and ventilation.
Leak detection, repair best practices, and EPA rules
Our EPA Certification ensures proper handling and leak repair procedures.
Maintenance Plans & Seasonal Tune‑Ups
Biannual inspections and cleaning checklist
Spring and fall maintenance keeps your system running efficiently year-round.
Extending lifespan and protecting warranties
Regular maintenance is often required to maintain manufacturer warranties.
Priority scheduling and member discounts
Plan members receive priority service and repair discounts.
Smart Thermostats, Zoning & IAQ Upgrades
Heat pump-compatible smart thermostats (Nest, Ecobee, etc.)
Not all smart thermostats work with heat pumps—we install compatible models.
Zoning for multi‑level homes and consistent comfort
Zoning system installations provide room-by-room temperature control.
Filter, coil cleanliness, and humidity control considerations
Clean systems run more efficiently and improve indoor air quality. If your air handler's ECM blower is failing or undersized, we'll recommend repair or upgrade options to improve airflow and comfort.
