All these HVAC dealers are interested in signing you up for $$$$ expensive service contracts. They don't want to work for a hourly rate & 15%`20 markup on parts. The parts markup in 400-500% without one of there so called service contracts. Their hourly rate is !25 per hour for a HS graduate with some on the job training. they have some 10-12 locations they have bought throughout the DC_MD-VA area doing this same service contract play and reading from their script of prices . If you contract with these guys you'll find the "service contract" is nothing but a license to wall in your house another day & charge you $200 per hour the next time. They prey on elderly people.
