Even though I'm trying to save up as much as possible on repairs there are things that I cannot do by myself. This includes changing the wires for electricity, the pipelines, and the air conditioning. Unfortunately, these happen to be the most expensive services. But thank God there is always the referral system that offers discounts to loyal customers. The last time I change the AC I called these guys: Heating Contractor & Air Con, Hereford | Sparta Mech not sure if they still offer discounts, but you can check it out on their website.
