We have been in business for over 30 years serving the Clark and Champaign county area (and beyond) providing the finest service, installations and consulting. FREE ESTIMATES ON INSTALLATIONS ONLY.
They have visited us several times for unrelated issues on an HVAC unit installed before I purchased my home. I use the home as a rental now, and they were always courteous to my tenants and easy to work with over the phone while the technician was on the job. The customer service is fantastic over the phone also when you first call or after calling for billing and follow on! Highly recommend!

We have always been more than satisfied with DeLong. Rate them the highest for professionalism. There workers are clean, courteous and knowledgeable. We wouldn't think of using anyone else. They give us peace of mind that if anything went wrong they would be here and fix it.
Description of Work: Initially we had a system maintenance. We then had a new AC and furnace installed. Each year we participate in their Smart Owner program of checkups and maintenance if needed.

We had our furnace checked by a company who provided a coupon on Angies List and they told us the heat exchanger was cracked on our 18 or so year old furnace. We were also told that after next year we would not be able to get a coolant? for our 25 y.o. air conditioner. We decided to buy a new furnace and air conditioner. That company sent a high pressure salesman to our home who spent several hours inspecting every room and FINALLY gave us an estimate on both a new air conditioner and furnace. We felt the estimate was way too high and contacted deLong who was local, and was recommended by friends and Angies List. Ted gave us an estimate that was a little more than half of what the other company told us for both air conditioner and furnace. When I told the other company their estimate was too high they said they would match De Long's but backed off when I told them how low DeLong's was. It really made me feel the other company was taking advantage of us big time- what if we had gone with them and paid thousands of dollars more not realizing how much the price was negotiable. We hired DeLong and when we turned on our old furnace, the blower wouldn't work. Ted got the furnace working with a temporary motor he provided that kept our old furnace working for two or so weeks until he could install the new furnace and air conditioner. Ted was always very responsive to our needs and we were very pleased with the installers and how they fit the installation into our schedule. We highly recommended deLong, their responsiveness, price, service and product, although we haven't used the air conditioner yet.
Description of Work: We needed a new furnace as the heat exchanger on our old furnace was cracked. We also purchased a new air conditioner.

The heat pump had to be replaced but we had to use another company to do that because the warranty did not allow DeLong to service that brand. So, we had to use a company recommended by Bryant. The warranty has expired and we've gone back to DeLong to do our work!
