"We had trouble with our furnace constantly shutting off and on and rarely getting to the set temperature making for some pretty cold nights! After 3 different companies came out to troubleshoot, we still didn't have answers other than recommendations to replace our 4 year old furnace. Don came out and solved the problem in about 20 minutes! He was friendly, professional and knowledgeable and we are so thankful for his expertise! We will definitely use this company again and have signed up for yearly cleanings/inspections!"

"During a serious cold snap my 50 year old boiler died. They came as soon as I contacted them and the next day they promptly replaced it with a brand new one. My new boiler is already up and running and the temperature in my 112 year old house is heating up quickly. Great service, polite young HVAC professionals."

"We hired Comfair heating and cooling to install our new system AC and Furnace, from the beginning they measured and explained everything in detail and made sure we understand the whole process. We are super happy with the results, just to mention they gave us lifetime unit replacement warranty. We highly recommend this company to friends and neighbours who need their service."

"Top Shelf was awesome! Very professional and easy to work with. I left Applewood Plumbing for these guys because I was tired of the way they treat their "Gold" customers and of paying their premium prices. Uli and his team were great - stayed until 9pm to make sure I had a working furnace after my old one conked out. They will be my go to company from now on!"

"Every step, from the estimate with the super friendly Ryan, to the final walk-thru with the always professional Gemini, was absolutely top notch. They installed a new furnace, A/C, and tankless water heater and we are very happy with the work and final outcome. The whole crew was wonderful!"

"Great company. One of the best heating companies I have used so far. tom gave me a reasonable price for a new furnace. The crew was fast and efficient on the installation."

"These guys are above excellent! I already had estimates from 2 companies for for a new furnace. One was way too high, and I just didn't feel right about the second one. I called One Hour and got an appointment for a quote the following day. Habib came and took all the measurements for the entire project and gave me an exact price for the work. He explained everything I wanted to know, including the high standards their company follows, from getting exactly the right heating capacity to the requirements for every one of their employees: from drug screening and criminal records to excellent work and cleanup. They have a great guarantee, without any of the usual "membership" stuff that many other companies have. (I asked Habib about the lower estimate from the other company, and he showed me that it was only an estimate that could change. So even though it was lower, it could have ended up being much higher.) The next day, Greg and Ryan came and installed the furnace. Wow! They came and did the work quickly, quietly, and efficiently. They cleaned up afterwards. Greg showed me the new furnace and how to use the emergency shut-offs, and how to change the filter. And he explained how to use the thermostat. I appreciate working with companies that are excellent, and I've found one here! I highly recommend them for any heating/cooling needs."

"Jimmie Ciccone came out and in less than a half hour got my AC system back running at top performance! He cleaned the sides of the condenser grill, checked the air handler, checked on frequency of filter changes and then found that the power breaker in the panel was off (apparently turned off and not recycled by the alarm installer). Once the system was running and pressure normalized he checked the refrigerant charge and said it was perfect!! He only charged for the service fee to come out!!! This is an honest and religious man (not in the evangelical, religion-for-profit sense, but in the Christian sense)!!!!! I will wholeheartedly recommend Jimmie Ciccone and True Blue Heating and Air to everyone who needs heating and AC work!!!"

"I was extremely satisfied with Apple Aire. I purchased AC/furnace...the work was done efficiently in 8 hrs, everyone I dealt with were very nice, polite, professional. I love the system, it works amazingly...a bit higher then I planned but worth it."
