Does anyone know a good HVAC man in Mesquite that won't charge an arm and leg to do a repair on a unit? My parents unit has not been working well for a few days and it's HOT! They are to old to have it 86 in the house. My dad thinks he can do the repair if someone will tell him what part he needs. Please message me if you know of someone and I'll get the information to them to call.
