I emailed them last Wednesday evening (after hours) and they called me the very next morning and came out to repair my ac unit. Unfortunately it was not able to be repaired, but I did have a brand new unit installed only a week later. I would definitely recommend using them. Services: Installation, Repair HVAC

A&H took care of us when our A/C needed replaced. Responsive and professional service before, during, and after. They even provided a window unit to keep us cool until the new installation! We recommend A&H. Service: Install AC

Our AC died on Friday, Bill came to our home and diagnosed the problem. His team picked up the new unit Monday, Cody was friendly and professional. Our new AC was up and running by 2 PM Monday. We highly recommend A & H to all my friends and family. THANK YOU!

Baldwin City Fire Department was in need of a timely installation of heating units in the bay where our trucks are parked. During the cold months it is important to keep these trucks from freezing so we can provide emergency services to those who need it. A&H was understanding and knew the importance of such a time frame. Our units were installed in time with no freezing to worry about. All the staff were helpful from office to installers alike. Will definitely use their services again. Highly recommend!

I wanted to share my positive experience with A&H in Baldwin City. First, let me say that I am *not* the standard HVAC customer and my job was not easy, simple or straight forward. A&H could have passed on this job in favor of more traditional work such as selling new equipment, but they took the challenge head on and delivered exceptional service and support.

We purchased a home to remodel in the Baldwin City Area. Major project. Although relatively new (1984), it used some obsolete construction methods that we missed in the inspection process. The home was built on a grade and utilized under-slab ducting. When we noticed poor airflow and children's allergies acting up, we scoped the ducts and found near disintegrated and collapsed duct work which circulated dirt and mold through the house.

When a plumbing leak occurred, the ducts filled with water. We knew we needed *major* work to reroute the airflow in the house. This is where the quoting began. We quoted 6 (Yes SIX!) companies for the work. Local HVAC contractors, commercial contractors, Large Chain contractors and a custom sheet metal shop for good measure. Every one sent young techs who simply handed us a quote for new equipment and shrugged when we asked about duct work.

Some quoted Mini-splits, which would have left our 4.5 Ton heat pump blowing only to 1/2 the house, which would have been far too much. One company we quoted even declined the work but asked if they could sell us a thermostat for coming out. When Dan from A&H Showed up, it was a completely different story. He worked up the flow analysis of the house, inspected the equipment, we scoped the existing ducts and he spent almost 2 hours going over different options.

We ended up deciding on extensive sheet metal work, rerouting half the hair to a plenum in the attic with downshoots to each of the upstairs rooms. Of course this required ductwork in the main hallway, but they made it look nice and a good place to hang children's artwork (Pictured). We were able to utilize existing equipment, fixed the airflow and ended up filling the existing ducts with concrete. 8 months later, we stayed warm and toasty in all rooms even during a cold snap! A&H Saw a problem and did hard work when other companies declined or tried to sell equipment that would not have solved my problem. Far as I am concerned, they are the only HVAC contractor I will be using going forward.

They will describe to you one thing they're going to do but what they actually do will cost a lot less for them but they want to charge the same. I was told I would have a vent that shoots into the laundry room. I HAVE NO VENT FOR THE LAUNDRY ROOM! Services: Install AC, Install heating system

A&H Air Conditioning and Heating removed and disposed of my old HVAC system and installed a new Carrier AC and a new Carrier Furnace. The HVAC technicians that installed my new Heating and Air Conditioning system were friendly, knowledgeable and did a great job installing my new system and answered any questions I had. The new system looks great and is working fine with no problems.

I have been a customer of A&H Heating and Air Conditioning for over 6 years and have used their planned service agreement (PSA) every year for dependable inspections and repairs as needed. I will continue to use their PSA program for continued inspections to keep my new equipment running at it's peak performance. All of the staff at A&H have been wonderful to work with and very helpful in getting this new system installed. Thank you to all the staff at A&H for this new system.

Worse experience of my life with this company. Ripped me off for $612.00. Put on a part which they charged me $480 for and then caused my compressor to blow up. Proceeded to tell me that they'll sell me a new a/c unit for $4200 and take the $ off for the part. Refused to refund me for part that was on the a/c unit for an hour before it blew up. No compasation for ruining my a/c unit. Told me I could finance a new unit at the rate of 17.9%. Wow.don't call this company if you want your a/c fixed.

A&H installed our HVAC system and plumbing when we built our house 10 years ago. We contract with them for the semiannual maintenance. All technicians have been very timely, friendly and professional. Very open and honest on any issues found and options for fixing them. Bill does a good job educating on products and making recommendations. Office staff have always been friendly and helpful scheduling appointments and verifying Warranty paper work.

Recently had an outside unit go out. Worked with Bill on repair vs. replacement cost and unit recommendations. The price quoted was price paid. Technicians were again timely and professional. I would recommend them.

I have a sunroom that was always heating up or freezing the rest of the house. Bill recommended a Carrier mini split with 2 heads. One in the sunroom and one in an attic room. Amazingly efficient and low cost to run. Now I'm sitting comfortably in the sunroom all year long & the installation looks like they were mounted as original construction.

We've been using A&H's service since we bought our home 5 years ago. We had to purchase a new A/C unit in May and we had great technicians and a great experience. While we were waiting for the new unit to come in they came by and installed a window unit so that we would be more comfortable. A&H is very helpful and responsive and I would recommend them to anyone!

Follow-up review. After continuing service with them another four years we finally got the news we were anticipating for awhile. The central heating and air conditioning units that were in the house when we moved in before out 22 yr. old daughter was born were headed for replacement. Cheaper to do both at once and today was the day. Cha-ching. That kind of equipment and installation is pricey.

You know that, I know that. Guys arrive at 7:30 a.m., are out of the house by 4:30 p.m. (my wife even made lunch for them) and everything installed including a walk-through to show us the new gear, and. wow, immediately, the heater is running less, running quieter, better moisture in the air. We're more comfortable, win-win. We are really happy. Installation looks like a million bucks and we are set for a long time now.

Amazing how this company continues to really impress us. Sure, go ahead and use Yelp to review that espresso shop for the 500th time. Never know when that might be critical, but a business like this and less than a handful off reviews? That's just sad. Take a good look at this one. These folks kill it with superior service.

Had them due work on a drainage problem from the washing machine. It took two times of them coming out to fix it right. Then the valve going into the washer started spraying water. I called and they claimed they did not touch that valve which is right behind the washer and I would have to pay them to come out after hours. Called aqueous plumbing be was there in under 15 minutes and didn't charge a thing.

A keeper. I recently moved into an older home with a somewhat recently installed furnace. The furnace had a bad exhaust fan so I called another company who came out and inspected it. After charging almost $80 for the inspection they tell me they don't have the part to fix it. So I called A&H. The tech suggested that I contact the manufacturer to see if there was a warranty on the furnace and the company indicated the furnace was out of warranty. A&H, on their own contacted the manufacturer on my behalf and pointed out that based on their records the furnace should still be under warranty!

I ended up only paying for labor which I was glad to pay since the tech was a 1st-rate professional. Not only that but A&H helped transfer the warranty from the original owner to my name. Blown away!
