 Trustindex verifies that the original source of the review is Google. Hi Kristen, Thank you so much for your help with our air conditioning system last Tuesday, and for sending over the detailed invoice! You guys absolutely saved our vacation! We would have had a really tough week trying to stay comfortable in that 90-degree weather inside. Since we are still new to the area, finding great vendors can be a challenge. Word of mouth truly is the best advertisement, and I'm so glad my neighbor recommended you. We are absolutely delighted with your service! Your technicians were wonderfully polite and incredibly knowledgeable. We would love to look into getting a service contract with you guys!

 Trustindex verifies that the original source of the review is Google. Excellent service by Charlie. He came to clean 6 mini split units. The original installation was done very poorly. Charlie went above and beyond making sure everything was cleaned, drip lines repaired, and made sure everything was working properly. The units cool much better. I highly recommend this company.

 Trustindex verifies that the original source of the review is Google. I needed a new a/c because mine was leaking.  I had 3 companies come out to give quotes on a replacement.  When United came out , they exactly what I was looking for!  It is a variable speed & runs only when needed. Cost saving & very efficient.  It is Amana & they are the only company that has this brand.  Much better than Carrier & Bryant, & quite a bit cheaper! The install takes a day & they make sure ever is working properly.  I am very happy with my new unit.  I would recommend this company if you need a mini split or a new a/c!

 Trustindex verifies that the original source of the review is Google. Everything from A-Z with United Refrigeration Heating & Air was OUTSTANDING! From the initial meeting with Lance to answer questions, get an estimate, and set a date TO the day of mini-split installation with Chad, Shay, and Jonathan, who worked non-stop to get the job done.  They answered all questions and didn't leave until we understood how to operate our new mini-split. The entire process with United was professionalism at its best!  Even the guy who called to get our paperwork for the permit (Mike Griner) was personable and professional.  Price was right, service was exceptional! And our Florida Room is soooooooo cool no matter how hot outside!!!
