"DJ did a great job of explaining what needed to be done and how the work would proceed. We've lived in our home for 50 years and NEVER had the ducts cleaned! Got a coupon in a mailing and set up the appointment. The team arrived on time. k Rob & Andre were very professional and we're happy with the work they performed. Will definitely call them back in a couple years for the dryer vent (didn't know it was such a hazard). Have already noticed how much more efficiently our HVAC system works now that the gunk is gone."

"Scott was wonderful to work with. I called that morning and he came within a couple of hours to service our AC. He was informative about our options to repair/replace our HVAC system. Will definitely be using Can't Heating and Cooling again."

"Jim did a great job. He quickly assessed the problem and then took our unit with him to work on it more. When he got back to us, the fix would have cost more than it was worth. He gave us options for a new or refurbished PC. We felt the refurbished was a good deal and chose that. He came back and set that up and we are very happy with it. He then took a look at my laptop and again took it along. He tuned it up and installed a speed upgrade we wanted. Of course, we paid extra for the new unit and upgrades, but we thought the price was very fair. Jim seemed very knowledgeable and responsive. We will definitely call him again if we need any computer services."

"Our AC stopped working the day before Father's Day. Jeramy came out, not only on a Sunday, but Father's Day! He quickly realized out AC had a freon leak. He quickly fixed the leak and added freon. He was in and out in a very timely manner! He did not charge us for a service call, even though it was a weekend! We would definitely use Jeramy again and recommend him to anyone!"

"I would like to advise you that the owner came out and took care of all the issues created by his less than adept and cordial employee My shower and sink drain perfectly now The leak that occurred immediately after the employee left my house was fixed The owner was pleasant and talented and did not charge me for any parts or labor even though he had to return twice to complete my work I am very well satisfied with the way my issue was resolved and would most definitely recommend froggy to anyone w a plumbing issue I was told that the employee who was so awful had been terminate."
