SHOUTOUT TO THE EMPLOYEE WHO PAID FOR MY MOTHERS FOOD AT MCDONALDS ON 07/22 IN ISLAND LAKE WE THANK YOU!

Scott routine checked our AC system. He was very professional and courteous. 5 stars to Scott.

Very professional on time and the guy that came out was very nice and did a great job


Excellent in every way--really top drawer operation. Extremely professional--know their business.

Fantastic service from start to finish. Knowledgeable, polite, responsive staff. Everything went smoothly and I am very pleased. Highly recommended.

So they were contracted as a vendor for my building that hadn't updated most of their HVAC systems in 20+ years. The company was communicative on the products and what was available for installation. The employees that actually did the installation were very smooth, it took a about a work day. They also have financing options available out to 18 months with 0% interest. Obviously replacing systems is expensive but everything was communicated and executed well.

fantastic...
One of the best providers of service to our home. If not THE best.
Always courteous; always get to the crux of the problem and a quick solution.
A pleasure to have them in our home...

After our aged whole house A/C system died, Althoff sent a representative (Jeff) the next day. Within days, a courteous team (Rob and Danny) workd in the sweltering heat of our attic all day to install a new system--whcih works perfectly. we are delighted with this company.

I have been using Althoff for years now. They have been doing maintenance on both the heating and cooling systems in the past three houses I have lived in. Through all those years they have been great. The technicians are helpful, prompt, and very friendly. I highly recommend them.
