The Lee Thompson Company has always been a very efficient and competent company to use. Most recently they came out to replace a faulty thermostat. Not only did they change out the thermostat but they came back a second time at no additional charge just to recheck something. The Emmerson Thermostat they put in seems to be working fine but I recently heard on the news that Emmerson is recalling these thermostats so I am waiting to see what The Lee Thompson Company says. Overall I find them to be extremely professional, upfront, knowledgeable, friendly and their technicians are up to date on current state of the art parts and machinery as it applies to HVAC systems. I absolutely recommend using The Lee Thompson Company, you won't be disappointed.
