Power surges can damage controls and compressors. Surge protection for both indoor and outdoor units is a smart investment.
Secure the outdoor unit on a level pad with proper drainage to prevent flooding or coil corrosion.
Shoulder season strategy
Heat pumps shine in mild weather, but correct defrost operation and thermostat programming ensure comfort and efficiency.
If you constantly battle hot upstairs rooms or cold basements, the culprit may be airflow—not the equipment itself.
Signs of ductwork issues
Large temperature differences room to room.
Whistling or banging in ducts.
Dust buildup and short filter life.
High energy bills with mediocre comfort.
Duct diagnostics
Total external static pressure check compared to blower specs.
Duct leakage testing and sealing recommendations.
Supply/return imbalance leading to pressure issues and infiltration.
Practical fixes
Add or enlarge returns, especially in closed-door rooms.
Seal ducts with mastic, not tape.
Adjust or replace undersized runs.
Balance dampers and measure actual CFM to target rooms.
A competent HVAC Contractor Nixa, MO will evaluate ductwork during hvac repair or hvac installation recommendations, ensuring comfort is solved holistically.

Humidity control
Maintain 40–60% RH to reduce mold, dust mites, and respiratory irritation.
Integrate dehumidification with your HVAC for precise control.
Ventilation
Balanced ventilation (ERV/HRV) exchanges stale indoor air with fresh outdoor air while recovering energy.
Kitchen and bath exhausts should vent outdoors, not into attics.
Purification
UV-C lights can inhibit coil bio-growth.
Advanced options include bipolar ionization or photocatalytic oxidation; request independent data and real-world performance validation before investing.
You can trim bills without feeling any less comfortable:
Thermostat strategies
Program or schedule setbacks: 4–7 degrees when away or asleep can save 8–12% annually.
Use geofencing for dynamic setbacks tied to your smartphone’s location.
Fan settings
Keep fan on Auto for cooling unless a pro recommends continuous low-speed operation for IAQ.
Continuous fan can help with filtration but may re-evaporate moisture in humid climates—monitor comfort.
