Heat pumps in Newton, NJ face unique challenges from year-round operation and seasonal temperature extremes. We diagnose and resolve these issues daily.
The reversing valve is the heart of heat pump operation, directing refrigerant flow to provide either heating or cooling. When this valve fails, your heat pump might get stuck in one mode, unable to switch between heating and cooling. In Newton, NJ, where we need both functions throughout the year, reversing valve problems create serious comfort issues that require immediate attention.
Our repair approach begins with comprehensive diagnostics. We test the valve solenoid electrically, checking for proper voltage and resistance. We measure temperatures and pressures on all four valve connections to verify refrigerant flow direction.
System blows cold air in heating mode or warm air when cooling is selected. Sometimes the valve sticks in an intermediate position, reducing capacity in both modes. You might hear a whooshing sound when the system tries to switch modes.
We test valve solenoid coils for proper resistance and verify control board signals. Sometimes the problem is electrical – a failed solenoid coil or control board issue – which is relatively simple to repair.
Mechanical valve failures require replacement, which our technicians perform expertly, including proper brazing and evacuation procedures to ensure long-term reliability.
During winter operation, heat pumps extract heat from cold outdoor air, causing moisture to freeze on the outdoor coil. The defrost cycle periodically reverses operation to melt this ice, maintaining efficiency and preventing damage. When defrost controls fail, ice accumulates, drastically reducing heating capacity and potentially damaging the system.
Sussex County's humid winters make proper defrost operation especially critical. We test defrost thermostats, timers, and control boards to identify failed components. Sometimes the problem is a faulty sensor reading incorrect coil temperatures.
Excessive ice buildup on the outdoor unit is the most obvious sign, sometimes completely encasing the coil in ice. You might notice reduced heating capacity, longer run times, or higher electric bills.
We test defrost thermostats, timers, and control boards to identify failed components. Sometimes it's a stuck reversing valve preventing the system from entering defrost mode.
We check for underlying issues causing excessive frost formation, such as low refrigerant charge or blocked airflow. Our comprehensive approach prevents recurring defrost failures.
Heat pumps in Newton, NJ require backup heat for extremely cold conditions when the heat pump alone cannot maintain comfortable temperatures. This auxiliary heat, typically electric resistance strips, also operates during defrost cycles to prevent cold air from entering your home. When auxiliary heat fails, you might lose heating capability during the coldest weather – precisely when you need it most.
Our technicians systematically diagnose auxiliary heat problems, testing each component in the supplemental heat system. We verify sequencers are energizing heat strips in proper stages and check individual heat strip elements for continuity.
Auxiliary heat failures often go unnoticed until extreme cold arrives. The heat pump might maintain comfort in mild weather, but when temperatures drop below 35°F, the lack of supplemental heat becomes apparent.
We test sequencers, individual heat strip elements, limit switches, thermal fuses, and contactors controlling power to heat strips. Often, we find failed sequencers or burned-out individual heat strips.
Our precise diagnostics save you money by replacing only failed components rather than the entire heat package. We stock common auxiliary heat parts for immediate repairs.
Unlike companies that focus primarily on either heating or cooling, Smith's Heating & Cooling has developed equal expertise in both aspects of heat pump operation. Since 2003, we've repaired thousands of heat pumps through every season.
Our technicians understand that heat pump problems can't wait for convenient weather. A heat pump failure in January means no heat; a July breakdown means no cooling. That's why we maintain true 24/7 emergency service with technicians on-call every night, weekend, and holiday.
Our technicians use digital manifolds, thermal imaging cameras, megohmmeters, and digital psychrometers. These tools, combined with our expertise, enable rapid, accurate problem identification. We test operation in both heating and cooling modes to catch all problems.
The complexity of heat pump systems requires technicians with specialized training. Our team receives ongoing education on reversing valve diagnosis, defrost control troubleshooting, dual-fuel system integration, and variable-speed compressor service.

Our emergency response typically arrives within 60-90 minutes, depending on location and conditions. Emergency service vehicles are equipped like rolling warehouses with common heat pump parts.
We stock capacitors, contactors, fan motors, defrost controls, circuit boards, refrigerant, and auxiliary heat components. This preparation means most emergency repairs are completed in one visit.
Emergency service pricing is transparent and fair. Maintenance agreement members pay no overtime charges. We never exploit emergency situations with excessive charges.
One of our most important services is providing honest guidance about whether heat pump repair makes financial sense. Our experience guides recommendations balancing immediate costs with long-term value.
Heat pumps typically last 15-20 years in Sussex County's climate. If your system is under 12 years old with good maintenance, repair usually makes sense. Minor repairs like capacitors or contactors almost always justify repair costs.
For 15+ year old systems facing expensive repairs, replacement often makes more sense. Consider that modern heat pumps are 30-40% more efficient, and old refrigerants are expensive and being phased out.
Financing through Service Finance and Synchrony helps manage both repairs and replacements. Many customers qualify for same-day approval with flexible terms.
