Martin and Brian did a great job installing our new IBC high efficiency boiler..!

Sarah Matz

Great service as always! Sergio went the extra mile to provide same day part replacement.

Margaret Cleary

We have used Guardian for many years. They installed a new boiler in our old Victorian a few years ago and do yearly health check on it. Always prompt and courteous. Highly recommend.

Guardian Heating & Cooling Service did an excellent job installing our heat pump and furnace. The installation was done by Jose and Raymundo, and they were thorough in installing important components that other major installers will skip to save time, like surge protectors, draining lines for the in-take pipe and leak detectors. They were very friendly and answered all questions. Our sale was done by Jonathan, and he was very friendly too and prompt in replying to all questions. I had questions on the efficiency of the units, and he was diligent in finding all answers and making sure I was satisfied. Through this process and receiving quotes and estimates from the many companies in Chicago, I've learned that all top-reviewed companies are not the same. Guardian was far and away the most knowledgeable and thorough in doing a complete and quality installation. I'm confident my furnace and heat pump will last a long time (with routine care).

Anthony, the service technician, came out, did an excellent job diagnosing why I was getting an extreme build up of condensation. He actually found out it wasn’t the furnace at all and was able to direct me to the appropriate source of the problem. My experience with Guardian is routinely cost and time efficient. Great job!

Well, I initially called about my AC unit that died. It was repaired and cleaned by Peter. I now realize why the cleaning of my AC unit was so inexpensive. Peter had that unit look close to brand new. At this time I found out the unit was 22 years old and the furnace was not far behind. I thought that due to the age of units I should pursue quotes on replacements. I met with Jonathan who provided me with proposals. I met the owner who added on some additional components that he thought would benefit my home. The end quote I thought was fair and reasonable. The new units were installed the following week. The crew that installed the equipment were extremely professional. I could tell they took great pride in their work. Their work was immaculate. I have seen installations of other type of equipment. Primarily in the world of telecommunications and I have never seen a cleaner installation. You all should be proud. If you couldn't tell, I highly recommend Guardian.

Ashley Walter

These guys are fantastic! The comfort specialist explained all my options and even let me know my A/C didn’t actually need to be replaced, something a competitor neglected to mention. The installation tech was a true expert who answered all of my questions and really went above and beyond to make sure everything was working right before he left, even though my old building had a couple of surprises for him. It was horribly hot and I am so grateful to have my HVAC system working! Now I know who to go to for quality repairs. What a relief as a new homeowner!
