We were having issues with our AC not blowing cool enough. We had our main AC company come out that we used since we had the house. While under warranty they replaced the Evap coil 2 years ago. When we started having cooling issues this year we called them out "out of warranty" to see what's up. They said the Evap coil was bad (without checking it). They said those coils were prone to have issues. I said "you just replaced it within the last two years, they can't be that bad can they?" They said yes and they recommended a new unit for $6000-$8000 roughly. This unit is a 2007 unit and has been warranty maintained for its entire life including all seasonal cleanings and inspections. But they said the 12 year life of the unit is up! So I decided to give A2Z a try. They came out, gave me up front reasonable estimate to troubleshoot. After I agreed, right in front of me, they found the leak in the dryer filter. He pumped the system with freon to get us going until he could get the filter. Once the filter came in (1-2 days) they came and installed it. It's been working perfect since May. The price was extremely reasonable even with the "old style" freon cost and I didn't have to get a new unit. Very happy, very pleased and if my unit does eventually fail, they will be the ones I will call to install the new unit. read more

You won't find better people or a better company to take care of any of your heating and air needs. No pressure and excellent service! We have used A2Z Heat and Air for over 10 years and not a single complaint. You will not find two more honest, qualified, and hard working people than Jim and Patty Waldron. We had the low quality original units when we moved into the house and they started having problems, and they were only 4 years old, pathetic! Jim kept those units going for 10 years until our main unit finally gave out. We finally had to get a new unit and Jim and Patty took great care of us, helping us to find a really good unit at a reasonable price. Because Jim installed the new unit properly, as it was not originally, he was also able to help take care of a water problem in my crawl space. I can't say enough good things about A2Z. Give them a call and you will be glad you did!! read more

After calling One Hour Air and Action Air I was quoted between $5200 and $6100 to replace an AC system which "could not be repaired". I contacted A2Z to quote me a new system. Jim arrived and immediately pointed out a few problems with my current system. Before he even talked about a new install he said, "let me check a few things". 15 minutes later, Jim gave me the good news that he could fix my current system for about $1000. He promptly returned two days later with the parts. In less than three hours my system was working and Jim not only met his promise but came in at $742. I can't say enough about the customer service, honesty, and quality of work that I got from A2Z. I will NEVER use anyone else for my HVAC system. Jim and Patty are class acts. Don't get burned by the con men at the big HVAC shops - call A2Z read more

I don't ever leave 5 stars! Jim and his wife are by far the best HVac service in the Clarksville area! Twice now with 2 different homes I have had other Hvac companies come to my home, and tell me that my HVAC units were completely shot and needed replaced quoted $4000-$5000. I luckily called A2Z, and got an out side inspection done. Both times Jim has come and investigated he has found that the previous technicians either didn't know their job, or were trying to force the sale of a brand new unit! A2Z has come to the rescue now twice, and I refuse to use any other technician! Jim is honest, knowledgeable, and in some cases has parts for units that no one else has so he can get you back up and running on cold nights or hot days! read more

I first called A2Z a few yrs ago when my HVAC stopped cooling. Jim was so informative as to what was happening & didn't try to upsell me. He got it cooling again & I was happy with that. I had the same issue again a few months ago & knew it was time to replace it. Did my research, got a few quotes from other businesses, & then called Jim. He came out again & gave me a quote. As a homeowner & single mom I appreciated his honesty. Not exaggerating...I saved thousands going with A2Z compared to the other ridiculous quotes I received! They just replaced it a few days ago and I couldn't be happier! Have already referred friends/neighbors to them if they ever have HVAC issues. read more

They go above and beyond!!! Honest, dependable, and all around great company. Had one company try to tell me needed new unit there was no repairing ours charged us the appointment fee and left me with a 4 month old baby and no heat in January. Called A2Z(Jim)for second opinion he came out that night, even though he was already home for evening. Jim was able to fix with 1 part for under $50! 5 years later unit was still running strong with no issues Won't use anyone else and suggest them to everyone we know. So nice to have a company you can trust and depend on that's NOT trying to rip you off. Can't say enough good things about Jim and Patty!!! read more

After hiring several companies to assess and/or fix various issues in my older home, I have discovered how difficult it is to find competent and honest workers these days! This is the first company that I have found who delivers services the old-fashioned way...what a breath of fresh air! Both Patty and Jim are very knowledgeable/friendly and the work performed was exceptional. My new HVAC unit had to be installed by a certain date and they made sure that it was completed on time. If I were you, I would look no further for your heating and cooling needs; it will save you a lot of time and expense. I highly recommend this company!! read more

Our upstairs unit quit blowing cool air, so I started looking for a HONEST company to aid me. Most other companies-that I had look at my unit did not take much time to explain to me my options clearly until I found Jim! He explained to me my options in a way only an experienced technician could, and I immediately contracted him to replace my unit. Jim and his crew showed up promptly and installed my new unit with precision and complete respect for our home- all at a very reasonable cost! If you want and honest company that will do the job right at a reasonable cost then call Jim @ A2Z Heat & Air. Frank Eldridge read more

Excellent service. I had to obtain bids my church's HVAC system a few years ago as we switched from propane to natural gas. Jim was the only one who didn't attempt to sell me a new unit. He made the switch for 1/10th the cost. This company is who I have to do my home system preventive maintenance. Patty and Jim are both very friendly and very knowledgeable about these home systems. They don't treat you like just another account. They diagnose and their estimates are pretty much on the money if you have a problem. I most definitely recommend them over any of the other local and regional HVAC providers. read more

Absolutely the best service i could have possible asked for ! The team went over and beyond what i could have imagined. I deal with lots of repair/installation businesses and this one is by far the best i have ever worked with . I own a home in Clarksville and the air stopped working. They performed a diagnosis quickly, gave me an estimate and a time in which the repair would take place and they were true to their word ! I could not have been more satisfied. Very polite and understands what it means to service a customer !!! Thank you very much for a job well done ! read more

This is a professional and wonderful Heat and Air conditioner service provider. We have used then twice in the past few years and both times the service was perfect. Both times the issue and options were explained in terms we understood. The A/C repair was fast after a detailed assessment os the system. Both times we have contacted A2Z Heat and Air we have been happy with not only the professional service but the very fair cost. Highly recommend A2Z Heat & Air if you live in the Clarksville TN area. read more

We have been using A2Z Heat & Air for 9-10 years with two different houses. They have always went above and beyond. Jim has helped us get the most out of our system without pushing new unnecessary equipment. He is very thorough and explains all of the procedures that he's done and answers all of my questions and I have a lot. A2Z manages to keep us warm and cool year round. I would highly recommend them to everyone and I do to all of my neighbors and friends. Julie M read more

I am a homeowner for over 30 years in Clarksville Tennessee. I have used three of the largest heating and air companies in Clarksville one of them had a :-). The services became so pushy about sale,sale,sale. I decided to try a smaller company A2Z. I am so happy with this company. A2Z technician was very knowledgeable and polite. I also have recommended them to two of my friends. Thanks for the great service installing my air conditioning unit. read more

Jim is the best!!!! I wouldn't use anyone else. I get anxiety thinking about Jim quitting. We have used him for 10 yrs and he is always prepared and knows the quickest and most cost efficient way to fix things the correct way. I have called him and he would tell me a quick fix instead of taking my money to do something simple. He has waved fees to help us in time of need. We appreciate Jim and A2Z. read more

A2Z was very customer friendly. They were recommended to me by an associate and I would recommend them to others. I live out of state and needed quick attention to a house rental. Their technician diagnosed the problem and had an estimate to me within 24 hours of contacting them. The work was completed and system back up and running quickly. I will use them again. read more

When my 22 year old furnace/ AC needed to be replaced I had several HVAC companies come out and give me estimates. Jim and Patti are extremely wonderful, knowledgeable, and above all honest people. They checked all the boxes: professional, courteous, expertise... AND they gave me the best deal possible! Thank you for going above and beyond my expectations!!!!!!!! read more

Absolutely the most honest HVAC company I have ever dealt with. I was referred by a friend several years ago when another big name company in town wanted to replace both units on the home. A2Z came out and serviced the units, no need to replace, and they ran great. I would rather wait for A2Z to come out rather than have another HVAC company touch my units. read more
