Heat Pump Buyers Guide

This heat pump buyers guide is designed to help you get the best of your purchasing a new heat pump. Before signing any contract, including for heat pumps, it is crucial to consult with the installation contractor. Sizing the system correctly is of utmost importance for both air conditioners and heat pumps. A Manual J calculation should be provided by the contractor, and if not, it is advisable not to proceed with the contract. Neglecting this step can significantly impact the efficiency of both heating and cooling.

Noise levels also play a significant role when purchasing a new system. Make sure to review the product literature and ensure that the rated decibel levels are suitable for your needs. Avoid the mistake of investing in a system that will cause continuous frustration due to excessive noise throughout its lifespan.

Another important consideration is the geographical location in relation to the balance point of the heat pump. The balance point is reached in winter when the outdoor temperature drops below a specific point, and the system starts to fall behind. This is when the backup heat source is activated. Each type of heat pump has its own unique balance point, so it is vital to discuss this with the contractor before finalizing the contract.

HVAC Equipment Warranties

Warranties are a crucial aspect to consider when purchasing HVAC equipment. A manufacturer that believes in the quality of their equipment will have qualified and well-trained contractors, as well as offer a basic warranty that provides decent coverage for the equipment. It is essential to fully understand the warranty terms before signing the contract.

Many people overlook the fact that most warranties only cover parts and not labor when buying new HVAC equipment. Additionally, it is important to register the warranty within the manufacturer’s specified timeframe after installation. Although reading warranties may not be the most exciting task, it is necessary to comply with all the conditions outlined in the warranty.

Conclusion | Heat Pump Buyers Guide

Purchasing a new heat pump system involves numerous factors to consider. By making informed decisions, you can enjoy many years of efficient heating and cooling. Prioritizing efficiency will also help reduce energy bills in the long run. Lowering utility bills and saving energy benefits not only your budget but also the environment. We sincerely hope that our Buyers Guide assists you in making the right choice for your new HVAC system.

Heat Pump Indoor Fan Runs Continuously

Heat Pump Indoor Fan Runs Continuously – Richard, what would cause my heat pump indoor fan to run continuously? My indoor fan motor, on the heat setting, runs constantly and won’t cut off unless I lower the thermostat by 2° F. It is sometimes annoying for me to constantly change the setting just to get it to shut down plus trying to maintain a comfortable temperature without the fan running all the time. What could the problem be and is it something I can fix myself or do I need to call in a service company to make the repair? Thank you for your help!!


Heat Pump Blowing Cold Air | Refrigeration Heating Troubleshooting

Heat Pump Blowing Cold Air | Refrigeration Heating TroubleshootingWhy is my Heat Pump Blowing Cold Air? | Richard, love your website!! I used a few months ago to install a new thermostat, and you cleared some things up with the thermostat wiring colors I had problems trying to figure out. Thanks!!

Now I just turned on my heat pump the other night when it was cold outside. I wanted to warm the house up a bit since, in the daytime, it gets back up to reasonable temperatures. The heat pump is blowing cold air when the thermostat was set to heat.

I am just wondering if I hooked something wrong hooking up the thermostat, or perhaps I have a problem with the heat pump and need to call someone out to fix the problem. Regarding your reply to my original comment, I turned the thermostat up to 80° F. when the house temperature was 72°, and the thermostat was set to heat.

The supply vents did start blowing warm air. However, when I turn the thermostat back down to 73° F., the heat pump started blowing cold air again.

I look forward to your answer. Thanks again for all your help!! Rebecca. (more…)

Honeywell Heat Pump Thermostat Troubleshooting

Honeywell VisionPro Thermostat TroubleshootingHoneywell Heat Pump Thermostat Troubleshooting. Hello Richard! We have a Honeywell VisionPro (8000) thermostat with a Carrier heat pump that has two stages for heating and cooling. We are having problems with the staging of the system, especially in heating mode.

I know the problem also occurs in the cooling mode but it seems worse in the heating mode. The house seems to get uncomfortable even though the system is running and then finally after the thermostat gets to a certain point the second stage will turn on and we feel the difference. It doesn’t matter where we set the thermostat to for temperature. A friend of mine suggested I had a problem with a limit switch.

We also notice sometimes the outside temperature reading on the thermostat is incorrect sometimes and rarely matches the reported temperature from our News sources where we live. Just wondering what your thoughts are and if you can guide us in the right direction. We found your site by doing a search for Honeywell thermostat problems. Anyhow, can you help us, please? Thanks in advance!!! (more…)

Rheem Heat Pump Troubleshooting

Rheem Heat Pumps

Rheem Heat Pump Troubleshooting - Richard, I have a Rheem heat pump, and it seems like we have the same problems with it every year. We call the HVAC guy out to get it going again, but it seems the following year, it is the same thing over again.

He fills the system up with R-22, and it’s not cheap. Does my heat pump need this every year? Does the heat pump burn Freon like a car burns gas? How can I properly troubleshoot this problem?

That is year three, and the cost of fixing it keeps rising every year. In the Spring, when we turn it to cooling, we don’t get any cold air. I came across your site and saw that you take questions about HVAC. I appreciate you taking the time to answer my question concerning this matter. What do you suggest? Thanks!

This Rheem heat pump troubleshooting article mainly pertains to a refrigerant leak.  For another article on heat pump troubleshooting that is more diverse with heat pump problems, see our heat pump troubleshooting guide article.

Let us explore the question a bit further and see what really happens when you refill the unit over and over again, year after year. (more…)

Heat Pump Breaker Trips

Heat Pump Breaker Trips - Richard, my breaker keeps tripping for my heat pump. It seems to be a nuisance trip on occasion, and it usually happens at the most inopportune time. I am wondering what you think could be the problem to prevent these nuisance trips. I want it fixed so my heat pump is reliable. Thanks!!

This is a question sent in by one of the site visitors and is in a series of articles for heat pump troubleshooting and repair.

In this article, you will learn about heat pump main power circuits, including the reasons why heat pumps trip the breaker.

Heat Pump Breaker Trips

The Heat Pump Condenser Circuit

This is likely something you cannot repair yourself, and it could be dangerous (high voltage), so I recommend calling an HVAC contractor to look at the problem.
The typical split system heat pump (the most common type) have two separate circuits. One for the air handler and one for the condensing unit. Consequently, this means you will have two separate breakers in the main power panel, one for the air handler and one for the heat pump condenser.

Based on electrical code, these breakers, as with each breaker in your panel, should be labeled for the appropriate circuit location/appliance. That is not always the case. That is, the panels are not always labeled, and when they are labeled, they are not always labeled properly. It may be necessary for your HVAC technician to troubleshoot this issue to figure which circuit is tripping, the air handler, or the heat pump condenser.

Heat Pump Breaker Trips

heat pump breaker tripsA breaker trip for any appliance including a heat pump is usually caused by a dead short in the wiring or a motor. I usually say because there are some cases where the breaker was found to be bad or defective and would give nuisance trips. Once the breaker was replaced, everything worked fine according to normal specifications. A bad breaker can easily be replaced. However, this should be done by a trained professional, and a basic check of other components needs to be done to make sure these components did not cause the breaker to go bad.

Heat Pump Breaker Trips - NEC

The panel in the photo is an open electrical panel with breakers. The breakers installed must be sized properly for the amp load and wires size. Consult the NEC tables for proper wire sizing based on ampacity. Every electrical component in your electrical system is designed for a specific load or a specific number of amps.

A common residential heat pump condenser will have a number 10 wire which terminates in the main electrical panel to a breaker specifically sized for the ampacity of the condenser. This ampacity calculation is generally on the heat pump condenser on a label provided by the manufacturer.

Components from the termination at the condenser to the termination in the main electrical panel need to be sized according to the listed ampacity rating. The ampacity rating is usually list by the manufacturer. That includes wire size, breaker size, and fuse sizes with the fuses being special-purpose slow-blow fuses to take into account locked rotor amps (LRA) or starting amps for the compressor.

Troubleshooting electrical breakers should only be done by someone trained in electrical safety. Breakers are inside a high voltage panel and are very hazardous.

Reasons Why the Breaker Trips for a Heat Pump

Here are the basic reasons that will cause your heat pump breaker to trip along with basic explanations:

  • Bad breaker - this is described above. Can also be classified as a loose breaker (described below).
  • A dead short - this is when two wires touch and this could be a bad motor or a bad compressor. The windings in the compressor could go bad and when they do they cause a dead short in the windings. A heat pump condenser contains the compressor. If the condenser is fused, it can blow before it trips the breaker. However, it can also trip the breaker depending on the sizing of the fuses and the breaker. A dead short can occur in the air handler or the heat pump condenser.
  • Power supply. That can be caused by brown-outs in the summer or by a severe storm with lots of lightning. If some appliances in your home are working properly, then you need to call the power company to have them solve this issue for you.
  • Poor maintenance. A dirty clogged air filter or clogged condenser coils will cause the motors and compressor to operate at higher than normal amp draws. That creates a lot of heat from the extra electrical energy used. This not causes a higher power bill but can also lead to heat pump breaker trips. Make sure you properly maintain your heat pump not only to prevent nuisance breaker trips but also to save energy. HVAC preventive maintenance goes a long way in comfort and energy savings.

Never reset the breaker more than a few times. When a breaker trips continuously, it means you have a serious problem that needs to be addressed before the breaker is reset.

Heat Pump Breaker Trips

  • Mechanical lockup of a motor or compressor. A bad bearing or a rusted bearing can cause the motor or compressor not to start and run properly. That creates a lot of friction, keeping the motor or compressor from moving freely. That will cause the motor to work harder and create a higher amp draw and more heat.
  • A bad capacitor including start and run capacitors - Capacitors are essential to single-phase motors. Start capacitors and run capacitors are designed to help the motor run more efficiently and in the case of a start capacitor designed to help the compressor start. A bad capacitor can cause heat pump breaker trips.
  • Loose electrical connections - this can include connections to the heat pump itself or even a loose breaker. Loose connections cause a higher than normal power draw. That increases the heat and can lead to other problems that will eventually fail the heat pump.
  • Short cycling - Short cycling of a compressor can cause heat pump breaker trips.
Additional questions from our readers:
My heat pump breaker won't reset?

If you have reset the heat pump breaker and it continues to trip then you have an electrical problem. It could be the breaker that is bad or an electrical problem causing the heat pump breaker to keep tripping. It’s difficult to definitively answer this question if it’s an electrical problem. See the above list for possible problems that would cause the heat pump breaker to keep tripping.

Can my thermostat cause the heat pump breaker to trip?

The answer is no. The thermostat operates on an independent low voltage circuit. The heat pump breaker operates on high voltage.

What to do if the heat pump breaker keeps tripping?

The first recommendation is to call for service after checking some basic things. We have a checklist here before calling for service. If, after checking the basics and your heat pump breaker keeps tripping, call a professional. Replacing a breaker or troubleshooting a breaker problem can be dangerous.


Remember, safety is very important, and doing any of these things on your own is dangerous. It is best to call a professional to this work and troubleshooting the problem for you. Some people reset the breaker only to have it trip again when the issue recurs. Resetting a tripped breaker over and over again will not solve the root of the problem. Consequently, this needs the attention of a professional.
