Sergio is the best. A/C was tripping the breaker today and he solved the issue.
Great service, Mundo was very professional and truthful and love the fact he didn’t not try to scam me like other companies do or have done!
Incredibly professional, prompt, and transparent. From the estimate process to the installation, everyone at Guardian was very friendly and honest. Akeem and Will did an awesome job replacing my furnace and took extra care cleaning up afterward. They were true professionals. I will continue to use Guardian for all my HVAC needs.
Very good at what they do. They explain how and why they're doing what they're doing. Been a customer for many years.
I’m a service subscriber - they are prompt and professional, and seeing the same folks show up year over year is a great sign for me. All positive!
Raymundo identified and fixed our issue very quickly. He was cordial and gave me an explanation of what might have happened to our HVAC. I've had Guardian out a couple other times for routine maintenance and service repair - always impressed by their professionalism.
Guardian is a fantastic company. They take care of us and make sure our HVAC is running smoothly for the Chicago summers and winters. Nelson is a wonderful professional that is courteous, knowledgeable and quick on house calls. I can’t recommend them enough.
The Guardian team always offers to explain any potential or existing issues and helps make me a more informed client.
Great service. Peter came in for some necessary maintenance on our HVAC, and identified some major safety concerns, in addition to fixing my AC before lunch. There's no upsell here. These guys give you your options, in layman terms, and give a respectful, informed opinion on which they would choose. Never felt like he was pushing product or taking advantage of me. Will be coming back for any and all HVAC concerns.
Our AC unit went out and Guardian was there the next day to give us a quote and walk us through the options. The service manager was very knowledgeable and understood that this was a big decision for us. Once we decided to go forward, the new unit was here in two days as promised and the service technicians, Miguel and Will were on time (actually early) and ready to start. They worked very hard in hot conditions and were very polite and friendly. They installed the new unit in the time they told us it would take, explained the features and gave us some tips. I highly recommend Guardian and thank them for their hard work so we could have a cool house before a very hot weekend.
Sergio was fantastic. He was punctual, knowledgeable, professional and got my AC running great in no time.
The technician, his name just escaped me, was professional, thorough and I would have him back everytime if I could.
The office and technicians are very nice to work with. The technician always explains everything and inform me of any needed services that I need to have done.
Nelson and Eddie, the two technicians who serviced our HVAC system, were just wonderful. They were extremely knowledgeable and very professional. Moreover, they were able to answer all my questions, and did an excellent job working out the minor kinks in my HVAC system. Overall, I've found the service technicians at Guardian to be miles better than the competition. In fact, we started using Guardian because we were dissatisfied with our previous installer. I would definitely recommend Guardian to anyone who has heating and cooling issues.
technician called ahead of appt as directed. had all tools and completed task in a reasonable time. work area cleaned up and put back to normal. I trusted him and his work
We have been using this company services for many years. Knowledgeable technicians, very good customer service, helpful.
Guardian got someone out the next day to figure out why our a/c stopped running. The team quickly diagnosed and explained the problem, and the solution. They got the solution in place within an hour, improving the system in effort to prevent the issue from recurring. We recommend Guardian to all family and friends. Smart, friendly, and professional!
The technician Nelson was very informative, on time, did great work and was extremely friendly. He made me feel confident about the company and his work.
Both times, the technicians that came out were very personable, professional and eager to thoroughly explain everything they were doing. Very satisfied and secure knowing my HVAC is in good hands!
I had Guardian Services come give me an estimate for my home. Salesman was VERY professional and not forceful. Offered very good equipment, and explanations of why he recommends this for our home- Unico high velocity and Bosch heat pump ac. His knowledge was beyond what is expected of a salesman, more like a technician. Very polite. I agreed and proceeded with installation. I am very pleased with the installation crew, service and price. Strongly recommend this company !!!!!
