Most people wouldn’t go as far as adding liquid coolant to their cooling system, but I have an expired Heating and modern Air Conditioning certification from before I switched jobs and became an IT guru
I try to do as much as humanly possible to stop needing repairmen or tradesmen of any kind in our home. The cost to adjust the tank level on one single toilet was so much that I promised I would learn as much lake house service myself as I could. I even learned how to wire a new light fixture from our ceiling so I wouldn’t have to hire a professional electrician. Plus, there’s so much beach house service that’s straight-forward to do yourself regardless. Although I can see many sorts of situations where it would be helpful given the depth of the project, there’s actually no reason most people should suppose they need a seasoned professional painting business just to reseal the interior or exterior of their home. If they would rather save the currency and attempt it themselves on the weekends, there are plenty of tutorials on the web that can provide most of the tools and skills they need to get the job finally done. If you’re not doing a lot of trim work, it will be an even simpler project. I try to do our Heating and Air Conditioning service work myself as well, like filter variations, condensate line cleaning, and even refrigerant liquid refills. Most people wouldn’t go as far as adding liquid coolant to their cooling system, but I have an expired Heating and modern Air Conditioning certification from before I switched jobs and became an IT guru. Sadly, our Heating and Air Conditioning idea ran into a big issue that I was unqualified to repair, and I had no option however to phone the Heating and Air Conditioning business while I was in after hours on a Saturday night. Not only did I need a new fan motor for the air cooler, however our compressor outside was fried as well.
