Why Timing Your Attic HVAC Replacement is So Important in O’Fallon, MO
Unlike an HVAC system in your basement or a climate-controlled space, an attic unit in an unconditioned space is at the mercy of extreme temperatures. That’s why picking the right time for a replacement affects both the installation process and your overall comfort.
Downsides of Attic System Replacement in Summer
Think summers in O’Fallon, MO are rough? Now imagine working in an attic that’s over 130°F. While extreme heat won’t impact your system’s performance in the long run, it does present some challenges.
- Technicians will need to work during cooler parts of the day, which can extend the overall installation time. The same installation that takes one day in spring or fall could take multiple days in high heat.
- A temporary loss of cooling could leave your home uncomfortable during the hottest parts of the season.
