Common Heat Pump FAQs

Knowing when it’s time to replace my Heat Pump?
When the system begins giving you more problems than seem cost-effective to fix. If the system is approaching ten years in age and major components such as the compressor, reversing valve, accumulator or outdoor coil goes bad, it might makes good buy new instead of fix. Changing a compressor for instance, is somewhat less costly than changing the entire system, but new systems may provide you greater performance, lower operating expense and a brand new warranty on the whole unit, not simply the part to be changed. When faced with significant repair work, we can assist you make the ideal option.

My present Heat pump does not keep us comfortable. Should I replace it with a larger one?
No. The ductwork is already sized for the heat pump itself. So a larger heat pump would need bigger ductwork. The issue may be due to undersized ductwork, poor system design or setup. You may require ductwork modifications, a heat load computation, or potentially an energy audit to discover the problem locations and correct them. Some people just can not get used to the lower temperature level output and the longer run times of a heat pump as compared to an oil system for instance. They don’t feel as comfortable, despite the fact that the heat pump may be working perfectly fine.

What is the typical life-span of a Heat pump?
It can differ, depending upon how much the system is used and how frequently it is inspected or serviced. Typically, the average life-span of systems integrated in the 1970s and 1980s is about 15 years, however specific systems might differ and last much longer depending upon usage and how well they are preserved. An ARI survey revealed typical heat pump life to be about 14 years when advised upkeep treatments were followed. Newer units are anticipated to last even longer.

How typically should I change the air filter in my system?
Standard one-inch air filters must be checked each month throughout peak usage, and replaced if it looks filthy enough to impair the air flow through it. Some filters, such as electrostatic filters or electronic air cleaners, are washable; others, such as media type air cleaners are disposable and should be replaced, but a lot of those are developed to last up to 6 months, even a year.

Can I repair my own Heat pump?
No. Heat Pumps are on a 240 volt circuit. Severe shock or electrocution is possible without an extensive understanding of electrical energy. Likewise, cooling systems today are more complicated to service than ever before, now being comprised of solid state circuit boards and sensors. They generally need skilled attention in order to adhere to federal guidelines, such as the Clean Air Act which prohibits launching refrigerants into the atmosphere. An EPA-certified air conditioning specialist or service technician ought to be called at the first sign of trouble.

Can I put a cover over my outdoor Heat Pump?
Sure, if the cover was far enough above the top of the system regarding not impede the air flow discharging from the unit. And if it does not hinder servicing of the unit, then it might help secure the system from the bad weather like snow, ice, falling branches and leaves. But it actually isn’t needed. Heat Pumps are created for outdoor usage.

Should I switch to Emergency Heat when it gets below 35 degrees outside?
If you have a typical electric heat pump, the response is no. That would be foolish. A heat pump can still offer heat to negative 10 degrees. The heat pump and the electrical back-up heat work together – immediately. Now, if you have oil or gas back-up, then you have the choice to change to back-up heat (Emergency Heat) for more comfort. However it might be more efficient not to utilize it.
