Lakewood. 1976.

Andy and Sandy Stack started in the family home. Today the same last name does heating, cooling, plumbing, and electrical out of Avon and Sandusky.

1998: out of Lakewood, onto Lear Industrial Parkway in Avon. 2020: larger training room, same town. Brothers, sister, and Brian all work here. Techs train on real equipment so a 1928 house is not a surprise.

Electrical, 2015, Phil Faulhaber. Plumbing, 2021. Not a mall of trades — so a customer who already trusted the furnace did not have to interview a stranger for the water heater or the panel.

They still work on steam and hot-water boilers when the house has one — Andy built a reputation on those systems. That is one floor of the shop, not the whole company. Lennox Premier Dealer. ACCA. Radiant Professionals Alliance. If the work goes wrong — ask for Brian.
