HVAC 101

A heat pump is a key component of a home's heating and cooling system, typically located outside the house. Similar to a central air conditioner, it can both cool and heat your home. During colder seasons, it extracts heat from the outdoor air and brings it indoors, while in warmer seasons, it removes heat from inside to cool the space. Powered by electricity and utilizing refrigerants, heat pumps ensure year-round comfort without the need for separate heating systems. In colder regions, an electric heat strip can be integrated into the indoor fan coil for enhanced heating capabilities. Unlike furnaces, heat pumps do not rely on burning fossil fuels, making them a more eco-friendly heating and cooling option.

I am so pleased and thankful for OneStop. Our furnace started blowing cold air during a temperature drop and I have 3 small children. When I called, they came out right away. They diagnosed the problem and communicated what needed done and what they were going to do at every step so there was no surprises at the end. They got my furnace up and running properly and my children didn't have to sleep in a freezing cold room all night. They were such a pleasure to work with and they were so kind and professional. I will definitely be calling them in the future and have already signed up for their maintenance member program. If I could give them more than 5 stars, I would. THANK YOU ONESTOP!

had an old ac that died and wouldn't cool I called Onestop and they were out there asap and got my ac up and running again and they went through the whole system to make sure it stayed operational. I have elderly people in my home and temperature control is key. They were very detail oriented and prompt and even gave me options for a maintenance plan to save me money in the future... totally worth it. I'll be using these guys in the near future to update this system. Five stars for sure.


Great company to work with!! They arrived on time and did an amazing job for me. Other companies had kept putting me off and rescheduling me- it gets old. This company is a breath of fresh air. Best of all, their quote was accurate and there were no surprises wheeln payment time came. Definitely using this company again!!

I usually don't leave a review, but Onestop's technician stopped by and diagnosed our heat pump and air handler. Even though they gave me a really good price on repairs, I decided to get a new heat pump and air handler with warranties.
We had their comfort advisor come out and give us a quote. Their prices were so much better than the other companies we called, and now we are glad that we chose OneStop.
The installation was so much better than what was previously done.
I'm very picky on how things look outside, and it looked very clean and professional. They also advised me not to get the louder system because it is outside our bedroom window. Everything from ONESTOP was done right, and they have an awesome maintenance member program. Thanks again
