Frequently Asked Questions

Usually, it will take 4 to 6 hours to install a forced air system. However, this may vary depending on a few factors, such as how accessible the installation areas are and how big your home is.

Please clear any and all pathways to installation/work areas of tripping hazards and obstacles. You should also have the furnace room and the outdoor area where installation will take place readily accessible. If you are unsure of whether an area may be needed during installation, ask this question during your complimentary in-home assessment, or get in touch with one of our Home Comfort Advisors.

This question is hard to answer without knowledge of your home and lifestyle. Consider what you are looking for in an air conditioning system: what factors are the most important to your household? Educate yourself on the options available, and if you have additional questions and concerns, don’t hesitate to contact a Home Comfort Advisor.

This depends largely on who installed the system and whether or not it has been properly maintained. However, if the installation is well-done and regular maintenance checks completed, current systems can last up to 15 years or more.
