After searching for A/C repair, Design Air came to my home and within a 1/2 hour had My A/C unit up and operating at around $100.00 for the visit + parts. The Tech knew exactly what he was doing and was very fast and accurate. I now have them in my contact list. Great service!!

Design-Air is a "First Class" family run company!! Christine and Jim worked together to find the best Heating and Air System for the best price for our family home needs! Rich and I are blessed beyond measure with our new system!



This system is so good we have been able to keep our heat down 2-3 degrees lower and it is so quiet.



The technicians were very professional and a joy to have around our home for the day they were installing the complete system.



I will speak to everyone about what a honest and dependable company Design-Air is!

I used Design Air for installing a new geothermal unit that replaced my conventional furnace and air conditioner. Their quote for geothermal was the best price I got when compared to other places. They are kind and courteous. They also got the job done in a reasonable manner. Cleaned up after they were done. They sell Water Furnace brand geothermal units which is a trusted brand. The geothermal unit has been up and running for around three weeks so far and no problems or issues. I really like the geothermal and the work that Design Air did. Looking forward to a lasting relationship with Design Air as they continue to service the new geothermal in the years to come.
