HVAC Replacement – What to Expect

When is time for HVAC replacement?

When your furnace and air conditioner are more than 10-15 years, it is probably time to consider HVAC replacement. By replacing your HVAC equipment you will no longer deal with equipment breakdowns and repairs, and will ensure that your home will be more energy efficient and you will save money on your utility bills

HVAC replacement can be confusing, stressful and overwhelming due to huge selection and options that are available today on the market. DeMark Home Ontario will help you choose the best and right equipment for your home based on your preferences and your budget.

When you plan your HVAC replacement, contact different HVAC companies and ask at least for four, five quotes to ensure you are getting good deal. Also, it is very important to ask for references or read reviews about the company.

Before the HVAC System Installation

In order to provide you with the accurate HVAC replacement quote, most companies will do a free in-home estimate assessment in order to determine the right furnace or air conditioner size for your home. They will also assess your ductwork system, attic, crawl space, doors, and windows.

During the Installation

The duration of the HVAC replacement depends on how complex your system is and how large the contractor’s team is. While most furnace and air conditioner replacements take about five hours, some can take as long as eight. The professional installers should protect your flooring and move furniture to a safer location if needed. Your old air conditioner and furnace will be safely disconnected and removed.

After the Installation

Once installation is completed, the installer should fully test the new HVAC replacement system to make sure all connections are tight and the system is working properly. Once the new equipment passes the inspection, the HVAC team should instruct you on how to use a new system, maintain it and replace an air filter when necessary. Before leaving, they should clean up the area they worked on.
