Projects & Case Studies

Roof Top Units Installation for Toronto Chinese Methodist Church

In March 2024, we took great pride in helping Toronto Chinese Methodist Church in replacing six 25-year-old Carrier Roof Top Units (RUTs) and installed six energy-efficient Carrier RTUs. Since 1983, Toronto Chinese Methodist Church has dedicated itself to fostering peace and abundance through its ministries in Cantonese, Mandarin, and English in the Greater Toronto Area. With increasing repair and maintenance costs, installing new RUTs just makes sense. New RTUs reduced utility costs and improved indoor air quality. As your HVAC solutions provider, we are committed to excellence in delivering quality services.

Our furnace stopped working on a 2-degree day this Spring. We selected HECH based on the recommendations on HomeStars. A HECH recognition came within an hour of our call and got the furnace started again which we were really happy about. The unit was 27 years old so was on its last legs. We decided to replace it and our similarly aged AC unit with a new heat pump/ furnace combo. The sales rep set us up with an energy audit company so we could take advantage of the government’s greener home rebate. This reduces our cost almost in half. We’ll get both units replaced for the price of a furnace alone. The technician in charge of the installation was excellent. Great to work with and took care of our home.

I have the pleasure of having my Carrier air- conditioning system checked today May 18 (Ha…getting ready for the heatwave coming in two months’ time). The technician Harry came in on time. He checked several things including but not limited to refrigerant levels, debris left in the water pipe outlet, etc. I am pleased with the details because he had a checklist to follow. By the way, at the end, he reminded me that if the fan is a bit noisy or the time for the in-door temperature to drop by 1 C takes a bit longer say an hour then it is time to call the office for further follow-up. Thank you High Efficiency.

My AC unit broke down in my condo. Sergei was super responsive and recognized what the issue was right away. He communicated regularly to keep me in the loop of what was going on regarding ordering the new AC unit. When the new AC Unit arrived, he didn’t waste any time and came to install it that same evening! This man is so dedicated to his job, which is so rare these days. On top of that, he always had an amazing sense of humor. Hands down the best service you could ever receive!!! I cannot recommend Sergei enough! 11/10 .

Hi all, today I had one of their technicians come, his name is Chanton, and I have never experienced such great and honest company. As you know many companies will scam you for your money, not this guy. He was honest, I was 100% going to replace my furnace because I was told by multiple companies that it was broken and cannot be fixed and had to be replaced. Today I realized I was being scammed by every single one of them. This man came, looked at my furnace, and told me my filter has to be replaced. The second we took the filter out it began to work better than ever. He saved me from spending 10k on a new furnace. So honest, thank you.
