We bought this residential boiler a couple of months ago. It seems too noisy sometimes but the previous one made the same sounds, so everything is OK.
Installed this new one last month to replace the boiler we had for 17 years. Works well, now we’ll see how much fuel it needs.
A friend of mine recommended me to install this boiler. Can’t say it’s the best but works for me.
Finally replaced my old boiler and keep wondering why I haven’t made the change sooner. Got a good deal
All our installers have had training and comprehensive testing to ensure high quality heating and cooling installation. In addition, all our installers have undergone extensive background checks and are fully insured.
How long does an installation take? What time will they arrive? Do I need to be home for the installation?
Every installation is different and every project presents unique installation challenges, but we aim to have all installations completed in one day. Technicians will arrive at the prearranged agreed upon time and will keep you updated on the progress throughout the day.We always recommend that homeowners are present during installation, but if that’s not possible, we require someone over the age of 18 to be home during installation
What if the certified installer doesn't do a good job?
All of our certified installers are trained professionals that have undergone extensive training and background checks. However, if you are not satisfied with the installation, please contact us immediately. We offer a 100% Satisfaction Guarantee on all our installations. If you are not completely satisfied, we will remove equipment and refund your money – no questions asked!
Can I buy it online and install by myself?
HVAC or Boiler installation requires electrical, gas and refrigerant knowledge as well as familiarity with local bylaws and building codes. Failure to properly install HVAC equipment can create safety concerns and performance issues as well as void manufacturer warranties. For those reasons, we always recommends professional installation.
Do I still qualify for the 10 year manufacturer parts warranty if I purchase online?
Yes. The manufacturer will honour the 10 year parts warranty if a furnace or air conditioner or boilers is purchased online and installed by us.
What is the average life expectancy?
The average lifespan of an air conditioner is 15-20 years and an average furnace will last between 10-15 years. Annual maintenance and inspections can extend the longevity and efficiency of your unit. The average lifecycle of a boiler is typically between 13 and 17 years. It is important to note that boilers that are 10 to 15 years old may be 45% less efficient than newer models. A new eco-friendly model will save you a lot of money on your energy bill.
