Great technicians and service. Our heat went out in the middle of the night and they were here same day and install next day postponing plans they had that were less urgent. Pricing was reasonable and the level of attention given on informing me the progress from start to finish was excellent. Installed both a new furnace, ac unit, and re-ran ducts, new registers, and intake in the same day, whereas other companies were 6 weeks out prioritizing larger jobs. Would recommend them to anyone.

We used Rabbit Heating & Air to replace our 24 yr old furnace in our crawlspace & install new Central Air. They arrived on time, work masks due to covid & throughout duration of the job. They completed the entire job in 1 day. They put down coverings & cleaned up so well. The furnace & AC passed City Inspection with 1 visit. The crew was instructed by Rick to remove old insulation & re-connect a vent.
They were efficient from start to finish. They performed every detail as Rick instructed them to do. They didn't try to sale anything extra. The end costs were exactly what was on the estimate. Their pricing is very fair. They answered all of our questions. Rick showed us how to replace the filter & basic information. Barb assisted with the financing on the phone, it was critical in the process. The new furnace is working great, with so much more air flow coming thru the vents. We cannot wait to use the AC! They were ready to work & get the job done. So happy we chose Rabbit Heating & Air. We Highly recommend them! Lynn & Adam

Mark from Rabbit explained thoroughly my furnace's problem and cost alternatives. I decided to replace the entire non functioning furnace and he got in install scheduled for the very next day. The team was fast and did a nice job. Cleaned up after themselves too! I had a follow up call to them regarding a drain pipe and Mark was back out in two hours to make a modification to better suit our site. Thanks Mark, for providing great customer service! I'll use them again if needed and would recommend them to anyone.

From start to finish this company is one of the best I've every dealt with. Amazing people and great workers. They are thorough, kind and hard working. They were able to get me in for set up of my AC almost right away. They came out made sure everything was covered so nothing would get damaged or dirty. The job was a tough one and they worked all day at it. Everyone was courteous and polite and their financing options are so helpful. They are very fair with their pricing as well! I will be using them again for any of my HVAC needs. I highly recommend them!

I've worked with Rabbit Heating & Air on a few occasions. From replacing my furnace to, more recently, helping us get our AC back up and running (was over 90 degrees in my house. Yikes!) I've recieved nothing but exceptional and speedy service at a great price! Great work from great people. Highly recommend.

Rick and his team were so great and helpful in a time of need and so close to the holidays! A neighbor of mine referees Rabbit heating. My furnace went out on me finally and I didn't realize until late in the evening. I called after hours and spoke with rick. He was very Informative and helpful. He was out the very next morning to give me a quote. Prices were very reasonable and my new system works great. Alex and Gus were my installers and did a terrific job. Thank you

Yesterday I called Rabbit Heating to arrange for a basic inspection & cleaning of our furnace ($99). I was pleased to receive an immediate response from the company followed by a Tech arriving to complete the work the same day. This work was completed in a extremely short visit & my only concern is I hope that sufficient was done to ensure satisfactory operation this coming winter.

We called Rabbit for a second opinion after being told we needed a new heater. Their diagnostic visit was extremely reasonable, especially since we called them on New Year's Weekend. They were kind and helpful. Heater is now fixed and working great, without having to install a whole new unit!

Rabbit replaced our AC unit and did a great job. They went above and beyond, including reworking the ducting to ensure it was as efficient as possible. They responded quickly, were incredibly professional, knowledgeable, clean, friendly, and polite. They will be our go to for any heating or cooling needs in the future.

Our furnace went out right after Christmas, we were quoted $10,100 from a competitor, and Rabbit was less than half. Thank you so much!

I'm very happy with Rabbit. Rick was the technician from Rabbit. He did very good quality work. They showed up on short notice and fixed the problem. I'll call these guys again in the future for anything HVAC related.
