All reviews for Overcashier & Horst Heating and Air Conditioning

We are very pleased with the a/c unit. The workmen were professional and very informative. We have been satisfied customers for over 20 years.

Very good at coming out when needed desperately. Last year our ac went out and my wife has MS and could not handle the heat. This year I just got out of shoulder surgery and they worked me in. Thank you!!

we had emergency service on christmas eve and Denton got us up and running in minutes. He was friendly knowledgeable and did a quick fix.

Overcashier and Horst's service technicians were not only knowledgeable but extremely courteous. They cleaned everything up once they were complete with the project and it looked as though they were never there. I would hire them again.

Very happy with prompt, courteous service. Previously had them install a water heater when local company said there wasn't enough room for them to install one. I highly recommend this company!

Our old furnace couldn't keep up when the outside temperature fell below 10°. Overcashier & Horst installed a new furnace last year. Last night it was -13° (windchill -35°) and our house was WARM!! Thank you!

Geothermal HVAC system was blowing lukewarm air and it’s July 4th and 90 degrees out. Took a week to get an appointment, but was efficient and not too costly.

The response time on the return call for an immediate issue on my furnace was unbelievable and so professional they knew my system, helped me through it on the phone without a service call. They are great I will always look toward them for my AC and heating needs.

My Heat went out.
With in a day I had the owner in my house to discuss the different options.
Next morning I had a fully professional team install a new heater and return vent and filter!
Very satisfied customer.

We were very pleased with the professional quality of work, affordable prices, and prompt communication provided by Overcashier & Horst staff. The multi-zone ducted mini-split was certainly the best choice. Thank you to Brady and your team of experts.

Our 20 year old AC recently stopped working. We are a PCSA customer, so a tech came out the next day and determined it's time to replace the unit. Brady Grefe was quick to give us a quote, and after we ordered, he patched our current unit (free of charge) so it will run until our new one comes in. Brady has been fantastic to work with!

Randy and DJ just installed my new heating and A/C unit and did an excellent job. Very professional and you can tell they take pride in their work. This is the third time in 30 years that I've used them for new units (different houses) and I'd highly recommend them.

Randy along with Austin installed my new furnace and ac. They did a fantastic job. They were knowledgeable and willing to answer any questions that I had. It took 1 1/2 days because of the weather. Almost had everything done the 1st day though.

Overcashier replaced both my son's and our HVAC this summer. Great at providing options, installing our systems and follow up. The summer was cool and the winter has been warm. They install Trane equipment which is great quality.

I attempted to install a smart thermostat in a new home - something I've done before with no problems. I was not so lucky this time. The wires going to the thermostat were too short and in the process of trying to get them to work with the new thermostat, a fuse was blown, leaving me with no heat overnight. I'm new to the area so I started calling HVAC companies for help. Overcashier & Horst was the company who was most willing to help on such a short notice. They did tell me they had a full schedule but would squeeze me in. The tech was here about half an hour, quickly identifying and solving the problem. They won my business for future annual tune-ups and HVAC repairs.

Great service of installation of AC! The admin planning everything with us over the phone was a delight. The sales person understood our needs and gave us several options. The installers were very pleasant, did a little extra to make our system better, and throughly explained everything to us once completed. Would recommend! A+

O&H was the most professional and knowledgeable of all the estimates I got, and that held true throughout the installation process. My new Trane system holds at a rock steady 72 and I can barely hear it. Looking forward to many years of enjoying my HVAC investment!

I chose Overcashier & Horst based on the solid Google reviews and the desire for Trane equipment. They put in a new furnace and air conditioner for our home. We dealt with Brady on sales. John and Logan handled the installation. All were very professional and a pleasure to deal with. Our questions were answered. Our home was cared for. We expect this to be the start of a good long relationship with O & H.

Nick and Austin did a fantastic job installing my new HVAC system. They were professional and courteous. I asked a number of questions as the work progressed, and they were always willing to explain. I highly recommend this company.

Our new Furnace and AC unit is wonderful. Installation crew was very professional and personable. I was told by multiple other companies that fixing an upstairs "hot spot" issue would not be very successful. I am happy to report my upstairs is now just as cool as the downstairs! I am so glad we used this company and will continue to for any additional needs.

From the sales guys to the installers, everyone was very knowledgable, and accommodating. The team did a great job installing my geo system. After the job was done, Brady stressed the fact that I have a long term warranty and they will come out any time I have an issue.
