Free Estimates are available on-site to all of our clients at Lair Mechanical.

Because we focus on honest pricing with transparent diagnostic reports for your air conditioner or furnace, we do require our technicians to assess your unit firsthand. This means accurate estimates cannot be completed over the phone.

Why?

HVAC is a unique service that is often changing - Previous technicians have already put infrastructure in place for your unit that we need to assess firsthand in order to give you the most accurate estimate possible to avoid surprises. This guarantees you the most accurate estimate possible and fastest service for your home.
