Frequently Asked Questions

Your air conditioning system should be replaced about every 8-15 years. However, this is dependent on a few different things. If your A/C unit has been installed correctly and is properly maintained, it could run well even longer. If it is used too much or too little, if the system – including your ducts – is not routinely cleaned, or if you allow repairs to go unmade, your unit may need to be replaced sooner than later.

Because every home is unique, your best bet is to ask this question during your complimentary in-home assessment. The answer could also depend on what type of unit is being installed. But, regardless, it’s always best to ensure that the path is clear for the technicians to access the installation area. Move furniture if necessary and if you have children, ensure their toys are put away. It’s also good to have the furnace room clear, as well as the outside area where the air conditioning unit will be.

The installation of your new air conditioning system should not take longer than 4 to 6 hours. This is the average we’ve found across the board, but there are always different factors at play. These may include things such as what kind of system is being installed, whether there’s an old system that needs to be removed, or, of course, any unexpected complications. The preparedness of our technicians ensures that we never take more time than needed.

It’s not necessary that you’re home during the entire installation, but we do recommend you are there for the beginning and the end. If you are home when we arrive, it allows you to let us in and show our technician around. We prefer for you to be present at the end of the installation so that we can talk you through using your new equipment and answer any questions you may have.

This truly depends on what system and accessory package is being installed. For example, if you are only opting to have the unit replaced, it may not cost as much time or money. But if you are installing new air conditioning lines or getting ductwork done, it will generally take longer and cost more.
