 Trustindex verifies that the original source of the review is Google. After my new Navien combi boiler developed a whistling noise after just 2 years of use, I contacted Techno Gas based on their positive Google reviews. Diakyo and Mike diagnosed improper installation and missing components. After the problems gradually worsened over the following six months, I decided to have Techno Gas redesign the piping and reinstall the boiler properly.

They scheduled the work quickly. Mark and Jian completed the installation in one day, with Diakyo providing on-site guidance. The result was excellent: neat, well-organized piping, smooth boiler operation, and the whistling noise completely gone!

Techno Gas is highly experienced with Navien systems, has the necessary licences and insurance, and offers a 5-year parts warranty and 3-year labour warranty.

I am extremely satisfied and highly recommend Techno Gas. I will definitely use them for our annual boiler maintenance!

Thank you, Diakyo, Mike, Mark, and Jian for a job well done!

 Trustindex verifies that the original source of the review is Google. Great service. I have been getting my gas appliances maintained by techno gas for years. This year we had to update our boiler system. Mike, Mark and the crew took great care of our family. Thank you, we will only use them for any gas needs.

 Trustindex verifies that the original source of the review is Google. When the cold weather finally arrived in Burnaby, BC this year, my parents turned on their above-ground heating, and of course, it did not come on. We managed to get the pilot light lit, but the furnace would not come on. We first tried the usual AI route (lol) but eventually ended up Googling and finding these guys: Techno Gas Heating & Cooling Services Ltd.

Understandably, many companies were busy with their clients and their furnaces that needed attention during this first cold night of the season, but Techno Gas Heating were willing to come late at night (around 8:00pm, I believe) to address our problem. They first diagnosed it as a HONEYWELL VR8300A4508 STANDING PILOT FURNACE GAS VALVE issue, but when replacing the valve didn’t fix it, it became a sensor issue with the heat ex-changer.

Long story short: the furnace that circulated the water in the above-ground heating was old, as was the water tank (from 2015). After extensive discussion, and on Mike’s recommendation, we decided to replace both with a modern Navien NCB-240/130H high-efficiency condensing combi boiler (space heating + domestic hot water). By then, my parents were without heat for 5 days, so Techno Gas Heating came in on Thursday and after a day and a half had to entire thing replaced/installed.

Competitively, I’m not sure how Techno Gas Heating stacks up in pricing against other HVAC companies (and there are many in a Google search), but I can tell you that their service was professional and they delivered as promised. In the end, I have nothing but praise for their work and would highly recommend their service to anyone in need of a good HVAC company. Great job guys!

Common Air Conditioner Problems We Fix

Air conditioners can fail for many reasons. Our technicians diagnose issues accurately and provide safe, effective repairs for all cooling systems.

AC Not Turning On

Often caused by electrical issues, failed capacitors, thermostat problems, or safety lockouts.

Warm Air Blowing from Vents

May be due to low refrigerant, a frozen coil, airflow restrictions, or compressor issues.

Strange Noises

Grinding, buzzing, or rattling can indicate motor failure, loose components, or electrical issues.

Weak Airflow or Hot Rooms

Often related to blower motor problems, duct issues, or clogged filters.

Frozen Evaporator Coil

Caused by low refrigerant, airflow restrictions, or dirty coils.

Water Leaking from AC

Usually caused by a clogged condensate drain, frozen coil, or drainage issues.

Short Cycling

Frequent on/off cycling may be caused by overheating, low refrigerant, or incorrect system sizing.

Bad Smells or Odours

Musty, burning, or chemical smells may indicate electrical issues, mold, or refrigerant leaks.

If your AC is older or breaking down frequently, you may want to consider an AC Installation instead of ongoing repairs. Heat pumps are also a popular alternative for efficient cooling — explore our Heat Pump Services to learn more.
