What Does a Heat Pump Do?

A heat pump is a versatile system that provides both heating and cooling for your home. Instead of generating heat like a furnace, it transfers heat between the indoors and outdoors, making it one of the most efficient ways to stay comfortable year-round. During the winter, it pulls heat from outside air and moves it inside, while in the summer, it reverses the process to cool your home. This dual function allows homeowners to rely on a single system for all-season comfort. With proper heat pump installation, you can enjoy lower energy bills, consistent indoor temperatures, and a reliable solution for any climate.

  • Heating: Moves outdoor heat inside during colder months.
  • Cooling: Removes heat from your home and releases it outside in the summer.
  • Efficiency: Uses less energy than traditional furnaces or air conditioners.
  • Comfort: Provides consistent temperature control all year long.
  • Versatility: Works well with ducted or ductless systems.

Our Heat Pump Installations

At Stay Cool Climate Control, every heat pump installation is handled with precision and care to ensure long-term performance. We focus on selecting the right system for your home, setting it up correctly, and testing it thoroughly for efficiency and comfort. Our process is designed to give you peace of mind that your investment is protected and your home will stay comfortable year-round. With our experienced technicians and proven methods, you’ll never have to worry about shortcuts or rushed service. From start to finish, our goal is to deliver a smooth, reliable installation that supports your home’s comfort for years to come.

System Evaluation and Sizing

Before installation begins, we evaluate your home’s square footage, insulation, and overall comfort needs. Proper sizing is crucial because a system that’s too large or too small won’t run efficiently and may lead to uneven temperatures. By taking these factors into account, we ensure your heat pump is matched perfectly to deliver reliable heating and cooling year-round.

Safe Removal of Old Equipment

If you’re replacing an outdated furnace, air conditioner, or previous heat pump, our technicians remove the old system safely and responsibly. This step eliminates the risk of leftover components causing problems and prepares your space for the new installation. We also handle disposal in a way that complies with environmental standards for added peace of mind.

Professional Installation

Once the site is prepared, we install the new heat pump with precise connections and calibrations. Every detail—from electrical wiring to refrigerant lines—is handled with care to ensure the system operates correctly from day one. This professional approach helps reduce future repair needs and maximizes your system’s efficiency.

Thorough Testing and Adjustments

After installation, our team conducts detailed performance tests to confirm the system is heating and cooling evenly. We check thermostat accuracy, verify airflow, and make fine adjustments to achieve the best results. This ensures your home stays comfortable no matter the season and gives you confidence that your system is working at its peak.

Recommendations for Ongoing Care

A heat pump is a long-term investment, and maintenance is the key to keeping it reliable. After installation, we provide clear guidance on scheduling regular service and replacing air filters. Our team can also recommend ongoing maintenance plans to reduce the risk of unexpected breakdowns and extend the life of your equipment.

Always a great service from these guys. Jacob was out and went through my furnace and cleaned everything up. Very professional and easy to talk to. I’ve had them servicing my hvac for about 6 years now and they have always been able to make things work or work better.

On Jan 16, 2026 I called Stay Cool Climate Control to get a quote on replacing our old HVAC because the furnace was showing signs of imminent failure. I called the office in the morning, and Jeremy was able to come that afternoon. Jeremy looked at the old system and offered us multiple replacement choices. A few days later, after checking with 2 other companies, we concluded that Stay Cool was the best choice for us in terms of cost, efficiency, and equipment quality. We are not disappointed. Installation was scheduled for the following Tuesday. Brandon, Dalton, and Trey arrived on time early that morning, and after seeing the old system began removing it. Even though the outside temperature was in the teens and there was snow on the ground they worked tirelessly all day. By late that afternoon we had a new, highly efficient HVAC system up and running. Our thanks also go to Carter, who has answered many questions and was able to make the quick schedule possible.

HIGHLY Recommend. Our furnace quit right as a winter storm rolled in, and they sent someone out within an hour! Dalton figured out our issue and got our unit to work for just a bit longer until our replacement could be scheduled. Jake and Skylar handled our replacement. The office will send names and pictures of who is coming to your home, which made me feel very safe. Every person we encountered on the phone or in person was professional, friendly, and knew what they were doing. Pricing was fair and transparent, and they helped us get financing. Never felt rushed or pressured. A+ communication.

On time arrival to service my furnace for the winter. Travis was very courteous. He carefully reviewed his findings and answered all of my questions. As a realtor and homeowner, I strongly suggest that your HVAC system be checked, serviced and cleaned twice yearly. Use a professional like Stay Cool Climate Control.

Called 3 companies early in the morning. Stay Cool was able for me to take pics of the area while other companies wanted to come out 3+ days later to look while we had no hot water. Stay Cool was able to come out the same day which was a huge plus for us since we had not had hot water for 2 days already. Their price was also $350 and $700 cheaper than 2 other companies I have had in the past. Travis and Carter showed up on time and walked me through the tearing out and install of the new heater. They were courteous of their wet shoes with slips if they had to go to their truck outside when tearing out the old water heater. Carter, with our older heavy door headed to the garage it doesn't take much to close it. Please be easier in the future. There was an issue with the old water heater being taken up the steps with a dolly that scrapped all the way up the steps in pic 2. I called the main office, they apologized, and they sent Travis back out the next day to repaint. Ill still keep them in mind for future projects. thank you.
