Signs Your Heat Pump Needs Repair
Heat pumps run year-round in New Hampshire, handling both heating and cooling, which means they accumulate wear faster than seasonal systems. Catching a problem early typically means a simpler fix.
Here are the warning signs Plaistow homeowners most often notice before calling us:
- Cold air during heating mode: Often points to a reversing valve failure or a refrigerant leak.
- Grinding, clicking, or buzzing noises: Can indicate mechanical wear on the blower motor or compressor.
- Ice buildup on the outdoor unit: May signal low refrigerant levels or restricted airflow.
- Frequent cycling or failure to hold temperature: Commonly tied to thermostat or sensor problems.
- Rising energy bills without increased usage: A sign the system is working harder than it should to compensate for a developing fault.
If any of these symptoms sound familiar, don’t wait. Issues tend to compound when a system runs in a degraded state.
Should You Repair or Replace My Heat Pump?
Age and repair history are the two factors that matter most. A system under 10 years old without a significant breakdown history is generally a strong repair candidate. A system at or past 15 years that has required repeated repairs may cost less over time to replace with a newer, more efficient model. When our technician completes the diagnostic, we can give you a straightforward assessment so you can make the right call for your situation.
What Our Heat Pump Service Covers
Every service call starts with a comprehensive diagnostic assessment. We identify the immediate fault and look for secondary failure points that could cause problems down the road, so you’re not calling again in three months for a related issue. Our technicians are trained on all heat pump makes and models, including ductless mini split systems.
The full scope of what we offer includes:
- Diagnosis and Repair: Systematic troubleshooting of refrigerant issues, reversing valve failures, electrical faults, compressor problems, and more.
- New Installation: We size and install systems suited to your home or commercial space, handling all electrical connections in-house.
- Ongoing Maintenance: Thorough inspections, cleaning, coil checks, and tune-ups on a schedule that keeps the system running efficiently.
One advantage of working with Cornerstone Services is our single-provider model. If a heat pump repair surfaces a related electrical or plumbing issue during the visit, our team can address it without scheduling a second contractor. Electrical, plumbing, HVAC, cleaning, and handyman work all run through the same company and the same warranty structure.
