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.

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.

Scheduling preventive maintenance is essential if you want to protect your investment in your air conditioner. Routine basic maintenance helps prevent problems from occurring and extends the life of your air conditioning unit.

There’s just one more thing to do. You should consider the best time to install your new air conditioner.
If you have an existing air conditioner that is not working and summer is approaching then you may want to get this done soon. Even if you have a functioning air conditioner, the installation process will mean you will be without air conditioning for at least some time. There will also be some disruption in your home while work is completed.
Discuss your preferred installation timescale with your home comfort advisor. They will explain the process and work with you to keep disruption to a minimum.


We offer all kinds of services: buying, renting, installation, uninstallation, replacement, repair, maintenance and consultation. Only high-qualified licensed specialists. We sell you only what you need, no pitfalls.
