There are some inherent dangers in having an inexperienced or unauthorized person maintaining or attempting to fix heating and air conditioning systems in residential and commercial locations.

Let me tell you that I like real estate, so when an upgrade or repairs are needed I make the choice to use a licensed  contractor or handyman.  Painting, crown molding I typicaly use a handyman or painter; roofing, electrical, HVAC, plumbing or anything where someone could get hurt or it could malfuntion if done incorrectly you bet I use a licensed constractor.   Save your money buying generic groceries or skipping a movie, safety is too important to skip on things like this.

Sure cut back where you can and spend to be safe, it reduces your liability.  My personal rule is that I need to sleep at night.  Using a licensed profesional for items that need that sort of attention helps me sleep at night.


Just a few years ago in the Los Gatos, CA area a commercial property had a rooftop HVAC (heating, ventilation and AC) unit that was not working.  An unauthorized and inexperienced individual was working on it and the reukts were disasterous.  That work he performed started a fire which not only damaged the building but unfortunately, took his life as well.

This is not an isolated incident.  Recently, I was driving by the Campbell and San Jose border and saw a lot of emergency vehicles ahead.  When I got closer I could see the HVAC unit on the rooftop was the culprit.  Firemen with hoses out and on the rooftop it made me suspect an unauthorized person was working on the unit or the unit did not have regular maintenance and it caused the convenience store fire.

The loss of business or loss of life simply is not worth it.

There are some very basic troubleshooting items and filter changes that can be completed by a maintenance person or owner but whether commercial or residential anything more involved than that could be very dangerous.


It may seem like a great way to save some money but HVAC technical issues are a specialty, in fact this is one of the few trades that have headhunters to attract employees because of the extensive training and experience needed to do a safe and quality job.  Stay safe and protect your property by hiring a NATE certified technician for your heating and AC work.
