Most air conditioners and heat pumps installed within recent years come with a ten-year standard factory warranty that usually covers the cost of most operating parts. This is a great value to the homeowner, but the homeowner must do two things; the equipment must be registered and annual preventive maintenance is required. Alpha Air Conditioning has found that many homeowners fail to register and so we register for them and we contact them when their first preventive maintenance is due. Alpha Air Conditioning customers can depend on us to keep copies of those documents in our data base.
