LCS Heating and Cooling

Great, knowledgeable team to help anyway they can! Hector came for the annual furnace check up. Did all the tests to make sure everything was working properly and even talked me through some things to look for early signs of something was wrong. Which I really appreciate and think is interesting to know. Thank you!

For a non-emergency plumbing issue, I appreciate the opportunity to ask for advice before making an appointment. Appointments are easily scheduled; the technician's arrival is announced in a timely fashion and the work is done expertly and in a friendly manner, including checking pricing in advance and cleaning up after the work is done.
