About Dave Slife

Dave Slife is a lifelong Lakewood Resident. He graduated from Lakewood High School in 1971.

After working for another contractor for 12 years, he decided to open his own HVAC business in 1990. However, six months after he started the business, he was called up for Desert Storm. He was in the Army Reserve. When he returned, he still wanted his own business and with the help of some friends, he started again and has been going ever since.

Dave attributes his success to a lot of community involvement. A huge part of his business has been generated and retained because he is active and visible in the community that he serves. Slife Heating & Cooling, Inc. participates in all of the local events in town. As a result, the Slife name and brand are well known and have become a household name.

In his spare time, Dave sings Baritone in a competing barbershop quartet and two choruses. He is a Lakewood Auxiliary Police Officer, a member of ACCA, and Lakewood Kiwanis.

Dave is married with 3 children and 2 grandchildren. He and his wife, Mary Lynn reside in Lakewood – there is no place he would rather be.


I’ve known Dave Slife for decades, and I wouldn’t trust my heating and cooling needs to anyone else. Dave runs a tight ship, his office staff are friendly and polite, and his technicians are knowledgeable on top of that.

A good 15 years ago we installed an entire house HVAC system including adding new runs to the second floor, all on the advice of Dave. He put in a zone system so that we had thermostats on the first and second floors, a rarity in Lakewood. He put in excellent energy efficient equipment and his technicians were thorough. We could not of been happier, because the second floor is as equally cool as the first.

I’ve called Slife a few times and always have had excellent service! One time it was the dead of winter and I was pregnant and our furnace stopped working on a Sunday night. As you can imagine, the expletives were flying!
Slife came out and fixed our issue and it was very reasonable in cost. They even showed my husband what to look for the next time to cut down on diagnosis time and how to replace the thing that broke in case it happened again. Clearly, I’m up on all the HVAC lingo 😉
I only call Slife. They are lifesavers!
