Crystal Lake, IL245 HVAC Professionals near you

Vitaly was easy to work with, flexible, and honest.

I hired Jose to replace my HVAC, and he did a wonderful job. He was professional, honest, and fair. I would highly recommend him for any job!!

Robert is an allstar! My furnace had stopped blowing heat he was able to come over quickly and communicated as the time got closer when he was going to be at my door. Upon inspection things were more difficult than orginally planned, Robert worked longer and harder and had to run to the store to grab parts. He figured out what was wrong and was willing to run out and grab and install the parts that evening with snow falling down. Overall, excellently priced, great communication, knowledgable, professional. Everything I want and expect out of a professional. Will absolutely hire again!

Ezio was excellent and provided some great recommendations based on his observation of my furnace, even though he came initially to install my ecobee 4. He installed my smart thermostat quickly and gave some useful tips on how to best use the system after installation.

Vlad (owner of GTC) is very good & professional. Used him on 3 separate occasions - (1) replace heater. It went out on Dec 31, 2015 !!! Vlad came out in the evening, to see if it could be repaired on the spot, and then cam back first thing on Jan 2nd ( when the supplier opened so that he could replace the unit). Did everything cleanly! Reasonable price - even considering he came out on holiday. ( I tried to use ABC Heating emergency - quoted me $8000 or 2.3 times more - tried to use my desperate situation) . Anyways, Vlad did it better and reasonably priced! (2) Also used Vlad to replace my 10 year old AC. No problems, as expected. (3) Asked Vlad to come out and help with installing Nest thermostat. It's not difficult to do on your own - but wiring to the old unit looked messed up - and I didn't want to take a chance. Vlad cleaned and rewired it and helped me install the unit.

It was great dealing with an honest guy like John. he was able to come out and do an estimate on short notice and give us his professional opinion and best options without up selling us. Also recommended we get a few more estimates which furthers his honesty. Our HVAC system is old so we were prepared for the worst but wanted a second opinion from a pro which I got from John.

I received a call from the company on the day of the scheduled visit saying that the tech was able to come out 2 hours earlier than originally expected. Alex was efficient and concise and didn't give me a hard time about spending over an hour on the roof just LOOKING for the correct HVAC unit since it wasn't labeled. He identified the problem, quickly went to the nearest store to purchase supplies and had our AC back up and running in no time. It was pricey, however I have no idea what the ballpark cost on our repairs would have been so we could have been getting a great deal. Who knows!

Excellent job!!! Dave installed a flue pipe for me with quality materials and very good craftsmanship. He made sure everything was working properly before leaving. I recommend using him for your HVAC needs.

He is easy to work with, arrive on time, reasonable price and good attitude. Detailed analysis on the issue and presented good explanation of the fix. Would highly recommended this company for any HVAC issue and I am using this company moving forward for my regular HVAC maintenance.

We tried to install a smart thermostat on our own a few days before the 90 degree heat hit (like fools!) When it was not working, we called in help. It was a Sunday but he made the time to come out on our schedule (after 7 pm) to save us. Not only did he find out the problem, he helped us install a second thermostat, filled up our Frion and checked out our outdoor units. He was on time, thorough and incredibley helpful. Will always call him for our HVAC and AC needs!

I had an Emergency furnace issue a few weeks back and ARS HVAC came to the rescue. They had the part I needed and they were able to service my issue within a couple of hours.

The HVAC professional truly exceeded my expectations. He took the time to walk me through the problem with my water tank and from there he was able to help me to understand the solution. The work was neat and my family’s happiness was top priority. I would recommend him band utilize his services again.
