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!

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%.

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.

Rick Rodriquez was very professional and fair. Rabbit presents their pricing up front. They are very competitive and do not add fees. We compared to Costco contractor and they were cheaper. They flexed their replacement appointment around our family vacation but still fit us on their schedule on 97 degree days. They fixed numerous things: bad pad placement, moved the electric service box, doubled our basement return duct capacity, which greatly increased the air output on the second floor! Along with a larger and more efficient unit, our electric bill went down! I recommend Rabbit and will use them again!

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.

The owner is very knowledgeable. He was more interested in getting me the best equipment for the size of my house rather than just letting me buy the most expensive system. I bought a furnace from them and a year later i upgraded to central air. In my opinion and i did my research. i got not only a killer deal on equipment they supplied but the installers went above and beyond.

Everyone else i know that has central air, you can tell the installer just threw everything in as quick as they could. Not these guys, they really spent a lot of time and effort on the install. I am a skilled tradesman myself so typically my opinion when i hire someone to do work is that i could've done it better. That was definitely not the case this time. i was thoroughly impressed and got way more than my money's worth.

I highly recommend Rabbit Heating and Air. I hope to see this company continue to be successful in a market that is extremely difficult based on how much competition there is out there.

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 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.

Rich is a phenomenal AC guy. Didn't up sell me on any unnecessary equipment. Did a great job educating me on my AC and furnace. AC works great after his visit where he came a day early. Thanks!

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!
