We had an issue with our heater. Our house was freezing cold when we woke up with two little ones in the house, I was super panicked! We called to see if we could get it Looked at as soon as possible. They responded immediately and sent someone out. Rick came to the house, and he was very kind and explained what was going on. Overall, very satisfied with the service and the interactions. Would definitely use rabbit, heating and air again in the future.

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.

Rick at Rabbit Heating and Air definitely takes pride in getting a good job done. I had a 35 year old furnace and no AC, so I was looking to upgrade everything at the same time. He gave me tons of options which I definitely appreciate. Compared to the cheapest competitors who just said "We'll throw in an economy AC and furnace for ya", his detailed explanation on options really helped me feel like I was a part of the process.

Because I care so much about the environment, he was able to get me a High Efficiency Heat Pump/AC installed High Efficiency Furnace installed for a lesser price than the "Economy Models" from big name contractors, and while it's not the dirt cheapest installation, I feel good knowing I got a quality system installed. I recommend Rabbit Heating and Air 100%.

Great experience! We have been searching for an HVAC company to install a new AC system, furnace and relocate our outside unit to the other side of our house, and are so happy we found Rabbit Heating & Air! This project went smooth from start to finish. Rick came by, on time, to give us an estimate and thoroughly explained our options to us. He was extremely knowledgable about the products they offered for install.

We were so impressed, and of course the price was right, that we hired them on the spot. Rick said he could have a crew to our house the very next day and he actually did! He also promised he could get the work done in one day and they did! The crew arrived at 9:30 am and were done before dinner! These guys came in and got right to work. The crew was extremely respectful and even laid down protective coverings on our floors.

This project could not have went any better! When the guys were done they cleaned up, walked the job with us thoroughly, and left. They left ZERO mess! We had a contractor out the week before for a different project that slapped it up, left a mess, and left angry because we held them to their work so naturally we were cautious on who we were going to hire for this job.

We have lived with our new AC and furnace for the past couple of days and can honestly say there is a noticeable difference. While giving us our estimate Rick noticed we may need some duct re-routed and minor repairs to the way the system was originally installed and he was right because now our house actually feels balanced! Each room is cooling and heating properly because of Rick's suggestions! We could not be happier with the results! All around great company and crew!

Rick is a fantastic person to work with, and his team Alex and others are hard workers who do the job right. We had 3 quotes for a new AC system and theirs was the most honest & reasonable with a high quality product and excellent service. Would absolutely recommend them, we are very happy with our new system, the way it was done, and the cost.

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

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.

We have used Rabbit twice in the last year, first for an AC and then a heater. They were great for both. Good prices and prompt service. Always kind with great customer service, before, during and after installation.

I am pleased with the service. I have used them three times in the past two years. I am pleased with how thorough they are when they visit, but I am more pleased at the fact that they don't gouge me. So far I have had excellent luck. I will use them again in the future. As well, I did not think they were too expensive.

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!
