Your HVAC system is a major component of your comfort level at home and at work. Therefore, the installation deserves as much attention as you put into choosing your system and the analysis you did on how much it would cost you to operate it. The first step is choosing an HVAC company you trust to perform the installation. Make sure they have a quality reputation by reading reviews online and getting testimonials. Find out if their technicians are certified and go through continual education programs throughout the year keeping them abreast of the latest installation techniques. When a system is installed, is there a team leader or manager who runs the installation team? Be sure to ask if there is a safety inspection performed making sure the installation is up to code, both installation and safety codes. Will the technician show you how to perform simple tasks while they are installing the HVAC system such as how to change out the filters, and perform regular maintenance such as making sure all vents are clear of debris and the outside unit is free of obstructions. Once you are happy with the company you have chosen to perform the installation, you should ask about maintenance programs. Will the company have a money back guarantee if you are not satisfied with the installation? Do they stand by their work? Will they come out 24/7 if there is an issue and the system isn’t working? Will they perform yearly maintenance to evaluate the performance of the HVAC system and if so, how much does it cost? Is there a warranty program? You owe it to your household and business to make sure your HVAC system is the best it can be starting with the installation process.
