Schedule OnlineKeeping Irmo Homes Comfortable Year-Round
Irmo weather does not stay mild for long. Summer temperatures push past 100°F, especially around Lake Murray where homes take on constant sun exposure. AC systems run for long stretches during peak season, and small issues show up fast.
Winter brings a different set of problems. Overnight temperatures can drop below 20°F, and occasional ice events put added strain on heating systems. Systems that have not been checked ahead of time tend to fail when demand increases.
Storm activity and hurricane risk also bring power outages into the picture. That is why electrical systems and generator installation matter just as much as heating and cooling in this area.
