Smith Heat & Air is a locally rooted, family-owned business built on hard work, integrity, and a passion for helping people feel at home in their homes. Our technicians aren’t just trained professionals- they’re your neighbors. We live and work right here in Mechanicsburg, and we take pride in supporting our community by delivering reliable, friendly service you can count on year after year.

Over the decades, we’ve developed a reputation for specializing in residential HVAC because we genuinely enjoy the one-on-one connections that come with working in people’s homes. We take the time to understand your needs, explain your options, and recommend solutions that make sense- not just today, but for the long term. No pushy sales tactics, no corporate runaround- just honest guidance and quality workmanship.

At our core, we believe comfort is personal. That’s why we treat every project, big or small, as an opportunity to improve someone’s everyday life. Whether you’re calling for routine maintenance or facing an unexpected breakdown, our family is here to take care of yours. That’s the Smith Heat & Air difference.
