We live in a generation that watches the Home Improvement channel and DIY (Do-It-Yourself) programs around the clock. This can be a great thing! There are certain ventures where it makes sense to try it out on your own, but there are others where it can prove detrimental to attempt it by yourself. It can be for safety, cost, or other reasons. One such area of expertise best left to professionals is the heating and air conditioning field.

Don’t get us wrong, there are certain portions of HVAC analysis you can do on your own. For instance, you can keep a regular eye out for leaks or unusual noises, but when it comes to the repair of these items, it would probably be beneficial in the long run for you to call an HVAC professional. Your heating and air conditioning system is made up of a combination of electrical and chemical items. It’s principles are based on thermodynamics, fluid mechanics, and heat transfer, and the design of an HVAC system requires a certain knowledge of mechanical engineering and HVAC repair training. 

The most common motive for individuals to attempt to install or repair their own HVAC system is the fact that installation and repair can be costly. Rather than spend the money, they’d rather see if they can save some cash by doing it on their own. When it comes to installation, this is far from a good idea. Most residential and commercial HVAC installations require an HVAC contractor to design an intricate system, often with the assistance of engineers. Certain permits are required to even begin the process of installation and building codes must be met. If you are not savvy in these areas, you could be facing fines, or worse, from improperly installed equipment.

Aside from legal issues, when it comes to installation, there’s also the comfort in knowing that having your system installed by an HVAC professional generally ensures that the system is set to run at peak performance and efficiency. If you attempt to design the system yourself and install it, you may be inadvertently overlooking crucial pieces of the installation that will cost you more money in the long run because of a lack of efficiency.

As far as the risks for both installation and repair, there are many safety concerns. Remember, you are dealing with electrical components and chemicals. There is always a risk of electrocution, and exposing yourself to dangerous CFC’s (i.e. Freon). Would you rather risk your health, and possibly wallet, in the long run? Or leave it to the guys who were trained for the job?
