My brother was telling me that a gas furnace or an air conditioner doesn’t fail nearly as often as the electrical work behind it. Electricians get a lot more are just as important as Heating and Air Conditioning business, according to my brother. My brother used to repair oil furnace systems and air conditioning units back in the day, which is how he knows so much. A lot of the time, when he would get to the job, he’d need to contact an electrician. Furnace and air conditioners do break down occasionally, however more often than not it’s the wiring that runs them that needs replacing. Air conditioners and gas furnaces draw an enormous amount of energy to run, which can cause the wires melt or burn. My brother saw it happen all the time. No one checks to see if the breaker is tripped or if the oil furnace or air conditioning even have power before they would call my brother out to inspect. My brother said that before he’d even start looking into the problem, he’d check the electrical work of the air conditioning or oil furnace. If it had no power to it, then there is no way he’d be able to diagnose it anyways. He used to get a lot of calls in regards to customers window air conditioning systems, and those are so small that usually the reason they’d be acting a little weird was almost always a plug or wiring issue. Honestly, if he found that that wasn’t the issue, he’d recommend to the customer that they purchase another window air conditioning unit.
