4Most Energy Boilers & More

Excellent service! Found your servicemen to be knowledgeable, polite and very professional. Installation was done quickly and cleanly. I would highly recommend 4Most Energy to anyone looking for HVAC service or installation.

Had them come over and install tankless water tanks for a fairly reasonable price. Rey was explaining the system and had provided excellent customer care even during the product registration phase. Installation was clean and totally respectful, would recommend to anyone that's looking for this kind of service honestly - glad to see someone so caring and professional =)

We were very impressed by our experience with 4Most energy Boilers. The installation occurred within one business day of purchasing a new boiler and rad. The technician was very knowledgeable and did a professional job. The new boiler works smoothly, and the new baseboard heater looks great.

I had the pleasure of working with Ray and Syed who came in and installed the radiant floor heating for my basement as well as the boiler to heat the floor and the hot water to the home.They did an amazing job and were quick and efficient. I did have an issue with the hot water a few days later and Ray was over the next day to troubleshoot and resolve the issue. I've had hot water since then without any issues. I would definitely recommend them if you're looking to upgrade your hot water tank to a boiler and/or heated floor.

Our 20 yr old boiler and 18 yr old hot water tank needed replacing. Upon reaching out to 4Most Energy, Rey came to assess the job, recommended an energy efficient Bosch combi boiler with very competitive pricing. This company was able to do the install the following week, arriving on time, completed the work to a high standard and left the house clean and tidy.We are very pleased with our new system! I would recommend Active 4Most Energy to anybody.

This is the second house where I had 4Most energy team install a Bosch boiler. Nice people who seem to like what they are doing. The installer Sam took his time to make sure the in-floor heating is working properly and that I know how to use it. Highly recommended!

Rey is a very honest person and knowledgeable about the HVAC system. We could not have had a better experience. I was so impressed that I decided to leave a review. He did troubleshoot and checked the entire system to ensure there were no other issues. It was an extraordinary experience. I highly recommend him to everyone and I would definitely hire him for my future HVAC-related needs.

Will definitely call Rey and 4MostEnergy again for future needs and will recommend to all my friends as well. The cost, quality and schedule for both supply and installation were the best and outstanding. Sales, management and installation team exhibited high level of professionalism. As we were living in the house for which the repairs and new installations were done by Rey and his Team, the installers worked hard and were very polite and considerate to finish installation in a timely manner without interruption. Both management and installer were very patient answering all our questions and accommodate out needs. Rey is very well updated with latest and greatest solutions available in market and tailored the best solutions fitting our budget and expectations. “THANK YOU for the amazing solutions and services. We are very grateful for all your timely, quality, and cost-effective services keeping our house warm in winter and cool in summer!

4Most Energy installed a Furnace, AC, humidifier, and a Tankless boiler in my house. I had an excellent experience with them. Rey was a knowledgeable technician who explained everything in detail and did clean ductwork. The new Boiler system also works great. Very happy with the quality of service provided by 4Most Energy.I recommend 4Most Energy to anyone who is looking for perfect service.

Rey and the team at 4mostEnergy were great right from the start. They were very responsive through the quote process, taking the time to understand what we wanted to provide an accurate price which was very reasonable. Work was completed on time and schedule and the team involved in the installation were very respectful of our home while they were working. Would highly recommend 4mostEnergy to anyone looking for a residential HVAC contractor in Toronto.
