This is the first time any sales person was so cooperative from the time looking for water heater till the time it gets installed he was walking with me.I will definitely recommend and do business again in future.

I used this company for my hot water tank installation. They were cheaper then my existing plan, offered me great incentives, and were extremely responsive. I’d been out of hot water for almost 1 week and when I called they replaced my tank the next day. Abdul was such a pleasure to work with. Great experience! Would definitely recommend them.
Our furnace stopped working and we contacted HVAC ontario for a quote on a new furnace. Their advisor was at our home within a few hours. He explained everything in detail . We purchased our new heating and cooling system from HVAC Ontario.

Who should I be get my water heater from?

There are many different options when it comes to rental water heaters i.e Reliance rental water heates, Enercare water heater rental, Vista, and chuck with the truck. We recommend discussing your options with a certified HVAC contractor to find out the best solution for you.

What size of tankless water heater do I need for my home?

Installing a wrong sized tankless water heater at your home can be costly and uncomfortable.  An oversized tankelss system will shut down more often resulting in rapid cycles that will cause an increase in furnace breakdowns.

A smaller sized tankess will constantly operate and try to maintain the desired temperature in your home, leading to frequent system failures and cold showers.

Be sure to get a properly sized tankless water heater that is based on your home needs to ensure that your tankless runs to its maximum efficiency throughout the day.
