Get matched with top central a/c installers in Round Lake, IL

"Great job completed by the Mr. Duct technicians Kirkland and Emmanuel. Will hire again next year!"

"Good. AC needed freon. Will possibly replace in spring. If so, will definitely hire again."

"These guys are great! We have an yearly maintenance contract with them for our AC and hot water boiler. They are professional and do great work! They are also very responsive as issues arise. Our older hot water radiator system went down on a Saturday night. I called Maggie and and Bob (one of the owners) was out Sunday morning and repaired our unit. They also installed a new hot water heater recently. Highly recommended!"

"Very nice technician, got some very old pipes off. Final system installed is very nice. We looked at a couple of different approaches, settled on a nice system that fits the fireplace nicely, looks great, and starts easily."

"Cahill installed my new furnaces in a professional manner and the units work very well. The annual service is thorough and complete. I am confident that the units are well maintained and not just given a cursory service. Installation of the ducts was done quickly and professionally and their advice helped me make the right decisions. They showed up to perform the work at the agreed time and completed the work efficiently. I didn't have to allocate a block of hours during which they might show up -- as with most service companies. I'm very pleased with this company."

"I called them for central A/C repair and furnace servicing, and they exceeded my expectations. The team quickly diagnosed the issues and fixed everything without delay. Their professionalism and attention to detail really stood out. Highly recommended for any HVAC needs."

"CR came to my house and gave me an estimate to replace my 19 year old central air unit. I called them the following Monday to see when they could do the job because it was going to be in the upper 80s all week. They were able to come out the next morning to do the install. Everything went perfect. My new air works great. Would recommend to anyone that needs central air installed."

"The guys showed up on time and did a very professional installation. They did n't cut any corners on the parts that they provided and didn't overcharge for them. They definitely knew what they were doing and explained in detail everything they were doing. I will not only recommend them but will use them again for any HVAC work in the future. Neil R."

"Excellent. Technician arrived timely. Tech was extremely courteous, professional and gave detailed explanation of central air system operating status. We have had Four Seasons perform seasonal check up on our heating and air conditioning system, and repairs when required, for over ten years."

"I needed to replace my 19 year old AC unit. ARS came out yesterday, quoted and installed today. Installers were neat and efficient."
