“I had a great experience with Spartan Heating & Air! I called to get a quote for a new air conditioner and spoke with Tanner. He was able to come out within just two hours, thoroughly explained my options, and provided a fair and straightforward quote. What impressed me most was how quickly everything came together. Tanner was able to return the very next day and install the new air conditioner. The entire process was fast, professional, and hassle-free from start to finish. It's hard to find a company that is this responsive and easy to work with. I highly recommend Spartan Heating & Air to anyone looking for reliable, professional HVAC service!”
“My 23 year old system quit working and the repairs didn't justify paying vs purchasing a new more efficient and updated Freon. Tanner was very polite, knowledgeable and helpful explaining everything to me. He cleaned up after the job and was very professional. Highly recommended for all your HVAC issues and installations as well as inspections. You will not be disappointed. Thanks Spartan Heating & Air!”
“I called Spartan / Tanner when my A/C system was not working. My system is older and I wanted to extend the life. I was impressed by the honesty, timeliness and reasonableness of the price. We will be utilizing in the future!”
