What customers said about heating system maintenance
Cornel's Plumbing, Heating & Air …Cornel was running a promotion that included one free furnace, AC cleaning, and removing a clog pipe for $89. The membership is over year with no commitment. Rodolfo just did it furnace cleaning and is great to work with.
Cornel's Plumbing, Heating & Air …Kenny is the real deal! He did a more thorough job than anyone has done since I bought the house 10 years ago. Very knowledgeable, good at explaining, and just a lovely person to work with! I am glad I became a member when Cornel was out to service my AC last June - there was no charge for today’s fabulous work! This company rocks.
Roth HomeDiego from Roth Homes AC and Heater service was great! He found and replaced parts of my heater, a bulb, the filter, and a part on the blower wheel. He serviced the heater and cleaned out my AC system. Diego waa very professional skilled and personable and communicates everything very well. Roth Homes is always so…
