A heat pump is the one system in your house that never gets a break. It cools you in July and heats you in January, so when it quits, it quits at the worst possible time. Novus Mechanical repairs heat pumps across Freehold and Monmouth County, and we start every call the same way: we find out what actually broke before we touch a single part.
Most heat pump trouble looks scary and turns out to be one bad component. The trick is knowing which one. A bad guess means a part you didn't need and a system that still doesn't work. So we measure first.
Your heat pump runs but the house won't warm up, or the air blowing out feels cool when it should feel hot. That is the most common call we get in winter across Monmouth County. The cause is usually a refrigerant problem, a stuck reversing valve, or a defrost cycle that isn't doing its job.
In summer it flips. The system runs nonstop and the house still climbs past the setpoint. Same equipment, opposite season, and the list of likely faults overlaps a lot.
Here are the failures we see most often:
You can find more general guidance on how a heat pump should run from ENERGY STAR, but a frozen coil or a burning smell is a call, not a DIY fix.
Find the real cause, fix it for good
We don't swap parts and hope. A heat pump is a closed system, and the symptom you see is often three steps downstream from the real fault. So we work through it in order.
We check the refrigerant charge first, because low charge is behind a huge share of "won't heat" and "won't cool" calls, and it almost always means a leak somewhere. We test the defrost cycle and the controls that run it. We check the reversing valve, the part that flips your system between heating and cooling, since a stuck valve will leave you frozen in winter or sweating in summer. And we measure airflow, because a clogged coil or a failing blower starves the whole system no matter how healthy the rest of it is.
That process is the same diagnostic-first work our technicians do on every job. Our team holds the NCI Residential HVAC System Performance Technician certification (#25-142-01) and the NCI Residential Air Balancer certification (#25-143-01), plus EPA certification (#P165BDDE28EAD0701) for handling refrigerant the right way.

Not every heat pump is worth fixing, and we'll tell you straight which side of the line yours falls on. A newer system with a single failed part is an easy repair. An older unit that needs a compressor, leaks refrigerant in more than one spot, or has already cost you a few repairs is a different conversation.
When replacement starts to make more sense, we walk you through the numbers instead of pushing you into a new system. If you do end up replacing it, that work lives on our heat pump installation page, and every install gets sized to your home, not matched to the old box. If your home runs on a gas furnace for heat, the repair side of that is covered on our furnace repair page.
Most of the heat pump failures we fix were avoidable. A coil that nobody cleaned, a filter left in for a year, a low charge that crept lower every season until the system finally gave out.
A system checked twice a year, once before cooling season and once before heat, catches those problems while they're cheap. Our maintenance plan covers both visits. For more cooling help, start at our air conditioning and cooling hub.
