Grant has enormous expertise and experience with HVAC, AC and heating systems. He thoroughly explained why he chose the equipment, including the pros and cons. The installation was professional and clearly he and his staff are dedicated to doing the job, in all aspects, with respect to the customer. I highly recommend Reasonable Air without reservation.

Grant came out and fixed a problem with our mini-split system. He tracked down the issue and repaired it within an hour, when another HVAC company would have insisted the equipment needed to be replaced. Reasonable Air really stands up to their name!

Grant is a great guy he knows what he's doing when it comes to his profession. He is on time and professional, diagnose the exact problem and took care of whatever needs to be taken care of to ensure that it was fixed properly. He did a thorough job and I'm very grateful for my friend Brandon recommending him and his company! I will call him again any time for my AC and heater needs!

Came within a day of request and fixed only what needed fixing! The "Big Guys" I have used for years for my HVAC preventive servicing could not "squeze me in" for three months.gurr! Service: HVAC repair

Grant is awesome! He went the extra mile for us and performed some on the spot tweaks (outside of the scope of the fall maintenance that we were scheduled for) to our unit to make it less noisy. He took time to explain things as well.

We called for an appointment to have our HVAC system checked and they came out in 2 days. Grant checked the system and did a thorough cleaning. He did try to sell us unnecessary stuff and the unit runs just as good as it did when we purchased it four years ago. I would recommend Reasonable Air, LLC to anyone thinking of purchasing a new unit or just needing their current system maintained.

I was told I needed to replace my entire unit by the first company that had come out to service it a few times. I got a weird feeling the last time they were out and made my calls. This is where I landed these amazing people! He came in, didn't rush, and figured out what was wrong. Lo and behold, I didn't need an entire unit! Thank goodness. We're up and running again and my house feels amazing! Thank you so much!

Grant and Reasonable Air did a great job installing a mini-split for our FROG. They came when they said they would and made sure everything was cleaned up before they left. Price was less than I thought it would be. Definitely recommend if you need any A/C work. Don & Donna

Under-promises and over-delivers. Grant was early to appointments, but called and asked if that was ok. Work came in very close to estimate and time allotted even though he found more components to replace and had to go get an extra part at his shop. The only difference I paid was for actual parts (and like a good, tradesman, he gave me the defunct ones and the packaging for the replacement to show the work was done). He'll be our go to from here on out.

I would never recommend this company. They were recommended to me by a work friend, my wife contacted him and he did come out quick and on time. My wife was told the initial fee would be $65 dollars, which she. told me and I was fine with. After he spent about 1 hour and 15 minutes checking my unit he charged us an additional $90 dollars for labor. Now, he didn't fix anything or replace any parts on my unit so I do not understand what I paid $145 dollars for.

After my wife called me upset about how he sprung this charge on her, I contact him and asked why the $90 dollar charge on top of the $65 dollar charge. His response was that the $65 dollar charge only covered 15 minutes of his time. This is a terrible business practice and I will never use or recommend this company. He provided a military discount which lowered the bill from $155 to $147.

Reasonable Air (Mr. Grant Shirley) recently replaced our AC unit. He quickly diagnosed the issue with our system, and he provided us quotes with a good, better, and best scenarios in a timely manner. We are very pleased with his knowledge and professionalism.

The a/c died on the 4th of July. My wife and I were planning to go out of town. I called Reasonable Air on the 5th. By 1:30 they had parts order. They fixed and tested the a/c while we out of town. We came home to a cool house. I like and I trust Mr Shirley. I will definitely call them the next time I need help.
Philip Judge
Grant is extremely knowledgeable and always does a great job for us. I would highly recommend Reasonable Air to family and friends.

Gary came the day I called, he was friendly and efficient. The company is named appropriately because he was definitely reasonable. Happy to recommend!
Tiffany Smalls
I rarely write reviews unless the service is beyond my expectations. THIS COMPANY IS THE BEST OF THE BEST!!!!! Mr Grant was able to look at my unit the SAME DAY to give an estimate. I explained to him that I will be needing a replacement unit for a home I will be selling so I wouldn't need anything fancy just affordable. This company offered the BEST RATE by far(I called about 7 companies) as well as extreme professionalism.

They were prompt and offered me great customer service despite me having a million questions. Ms Ragin Shirley is a gem and I thank her for being personable and professional making sure I understood everything. You and your staff deserve 5 stars and more. Thanks Again !!!
Sarah Snider
Grant did a great job servicing our HVAC units as well as fixing a few minor issues. The prices were reasonable and he didn't try to sell us on something that wasn't needed. I will definitely be calling him in the future.

The repairman came, went right to work and solved the problem. Ordered parts, returned and installed parts even though it was raining. Great job!
