My husband is a cheapskate. We used a refrigerator for two years after the handle broke off the door because it still cooled. He has piles of used screws and nails. He never throws anything out and he refuses to spend money if we don’t have to. And he is always looking for a deal. He won’t even pay money for routine HVAC maintenance. He insists on waiting until something goes wrong. Well, this time something went wrong and he insisted on waiting for a sale to have the HVAC unit looked at! Talk about a cheapskate! We live in a subtropical area, and like a lot of other people and businesses around here, we have central heat and air conditioning provided by a self contained unit outside our house, near the back door. I noticed several months back that the humming sound it makes sounded different and the force of the air from the vents wasn’t as strong as it used to be. I mentioned this problem to my husband and he told me that we would have the HVAC unit looked at when a local HVAC company has a sale on services. I’ve been watching for local sales and we ended up waiting three months. The air conditioning barely worked by then. The HVAC technician that came out explained what was wrong with it, and his explanation went right over my head. But, the point was, because we put off getting the HVAC repaired, it was now too late to repair it and we needed a whole new HVAC unit.
