Rabbit bear several other quotes and came out within 24 hours of my water heater going out. They communicated well. Prices were always clear and no hidden fees. Technicians arrived on time and were respectful and explained the whole process. They finished quickly and cleaned after themselves. I paid what I was quoted. This is how business should be done!

Spoke to Rick (service tech) on the phone he was very knowledgeable, professional, and a pleasure to speak with. We need more service men like Rick in this world!

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.

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!

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.

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 the guys did an awesome job! You can tell they take pride in their work. They addressed and rectified issues that were wrong with the previous installation, were very informative, professional, and curtious. I would highly recommend them.

Rick was very helpful in determining the correct a/c unit based on the layout of our home. His team was able to come and install the unit within a few hours. I am pleased with their diligent work and the price they offer for the a/c units. They even list their price online, so cool. Furthermore, the inspection passed with no issues at all. Lennox seems to be a fantastic brand and it cools my house in no time.

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!

Water heater not working, was able to come within 2 hours of calling- on a Saturday evening no less. No other company contacted was willing- although they deceivingly advertise hours as though they are available until 8 and even 10 pm. Rick was very knowledgeable and provided an objective assessment of the problem and the overall condition of the water heater. No sales pressure to upgrade, although incentive was offered with partial cost of repair credited towards a new hot water heater if replaced within the next 30 days. I was also impressed that he declined to take a tip after an efficient repair on a holiday weekend. Rabbit Heating and Air can definitely count on my future business! Thank you!

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.

I was very pleased with this company. Rick Rodriquez was proffessional and thorough. Rabbit Heating and Air was on time and came to my repair facility the same day that I called. We really appreciate you guys.

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!
