Heat Pump Repair in Roswell, GA
Because a heat pump works in both summer and winter, it logs more operating hours than a typical air conditioner, and wear can show up in either season. Roswell HVAC provides heat pump repair in Roswell for ducted, ductless, and packaged heat pump systems in homes and commercial buildings. Common problems include a system stuck in cooling or heating mode, an outdoor unit covered in ice that will not defrost, constant reliance on auxiliary heat, lukewarm air in winter, and loud noises when the system switches modes. These symptoms often trace back to a failed reversing valve, a defrost board or sensor, low refrigerant, or a bad capacitor. During Roswell's occasional hard freezes, a heat pump that falls behind can send electric bills soaring. Our technicians diagnose the actual cause and explain your repair options clearly before starting any work.

Heat Pump Repair Services in Roswell
Defrost System Service
An outdoor unit encased in ice usually signals a defrost control, sensor, or relay problem. We test each component and restore automatic defrost operation for cold weather.
Auxiliary Heat Problems
When backup heat runs constantly or never engages, we check heat strip elements, sequencers, breakers, and thermostat wiring to restore efficient staging and avoid unexpectedly high bills.
Low Heating Output
Lukewarm air in winter can stem from low refrigerant, a weak compressor, or restricted airflow. We measure pressures and temperatures to pinpoint why heating capacity has dropped.
Compressor and Capacitor
Hard starting, clicking, or tripped breakers often point to failed capacitors or compressor issues. We test electrical components and recommend the most cost-effective repair for your system.
Outdoor Fan and Coil
A failed fan motor or heavily soiled outdoor coil limits heat exchange in both seasons. We repair the motor, clean the coil, and confirm the unit is moving air properly.
Why Choose our Heat Pump Repair Experts in Roswell
Heat pump troubleshooting requires understanding how the refrigerant flow changes between heating and cooling modes. Our technicians test both operating modes on every call, so a hidden problem in one season does not surprise you months later.
We repair heat pumps of all major brands across Roswell, Milton, and Alpharetta, serving homeowners, property managers, and commercial clients. Service vehicles carry common parts such as capacitors, contactors, defrost sensors, and fan motors, allowing many repairs to be completed on the first visit. You receive clear explanations, written pricing, and honest advice about whether repair or replacement offers better value for an older system. We also share practical tips, like keeping the outdoor unit clear of leaves and snow, to help your heat pump run efficiently between visits.

FAQ
Heat Pump Repair FAQs
Answers to the questions Roswell customers ask us most. Still unsure? Call (770) 661-0066.
Why is my heat pump blowing cold air in heating mode?
Brief cool air during a defrost cycle is normal, but persistent cold air may indicate a stuck reversing valve, low refrigerant, a failed outdoor fan, or a thermostat set incorrectly. Auxiliary heat problems can also leave the home chilly in very cold weather. A technician can test each component to pinpoint the cause.
Is it normal for my heat pump to have ice on it?
A light layer of frost during cold, damp weather is normal, and the defrost cycle should clear it periodically. Thick ice that covers the entire coil or never melts is not normal. It usually signals a defrost control, sensor, airflow, or refrigerant problem that needs prompt attention to avoid damaging the equipment.
Why are my electric bills so high in winter with a heat pump?
A common cause is the system relying too heavily on auxiliary or emergency heat, which uses far more electricity than the heat pump itself. That can result from low refrigerant, a defrost problem, thermostat settings, or an undersized unit. During Roswell cold snaps, some backup heat is expected, but constant use deserves a service visit.
Should I repair or replace my aging heat pump?
Consider the system's age, the repair cost, how often it has needed service, and whether it uses phased-out R-22 refrigerant. A minor repair on a reasonably young unit is usually worthwhile. Major failures on older equipment often justify replacement. Our technician explains both paths clearly so you can choose with full information.
When should I use the emergency heat setting?
Use emergency heat only when the outdoor unit has failed or is damaged, as a temporary way to keep the house warm until repairs are made. It bypasses the heat pump and runs electric resistance heat, which is much more expensive to operate. If you need it, call for service as soon as possible.
