The People Behind W.F. Smith

Five owners run W.F. Smith today. Together they bring more than 140 years of combined industry experience.

Our core technicians and installers average more than 20 years in the trade. The same office team that answers your call schedules the visit and handles the paperwork afterward.

How We Work With Homeowners

Every visit follows the same approach, whether it is a repair, a tune-up, or a replacement.

We explain before we work.

A technician finds the problem and tells you what it means for your system.

You approve the price first.

You get a written price, and nothing moves forward until you say yes.

We are clear about our limits.

We do not service boilers, water heaters, oil systems, or steam systems, and the office tells you that on the first call.

Our rates stay steady.

Prices do not rise during a heat wave or a cold snap.

Heating and Cooling Services

Most of our work is residential. We handle air conditioning, gas furnaces, heat pumps, ductless mini-splits, ductwork, and seasonal maintenance.

We install Lennox central systems and Mitsubishi Electric ductless equipment most often, and our technicians service other major brands.
