Just like the normal person out there, air and heating conditioning contractors also make mistakes. Their mistakes will hurt the efficiency and performance of any HVAC system they have installed and perhaps still maintaining. It is also expected that as they make these mistakes, the customer will also be harmed, while hurting their business. Here are some mistakes HVAC contractors make.

Confusion on combustion safety
Once heating and air conditioning contractors have responded to an emergency, such as that of carbon monoxide, most of them run directly to the furnace into the heat exchange looking for cracks. In case they find the heat exchange is good enough, the issue is mostly taken as a false alarm. These experts even suggest the carbon monoxide alarm batteries should be changed. Nonetheless, professionals believe most of these HVAC contractors hardly understand back-drafting in the context of HVAC systems and neither test to see if it is the problem. They eventually leave behind very dangerous situations; depressurization and flue gases are not tested. In turn, you will immediately hear the individuals living in that home have been hospitalized for carbon monoxide poisoning.
Ignoring the air flow
If all contractors did their job well, not many experts would be going from one home to the next in search of a duct problem ailing the HVAC system. As a heat and air conditioning expert, understanding the airflow is very important. The duct system will not be as small as many HVAC contractors make it.
Ductwork sized wrong
Most HVAC contractors who are called to look into an issue other contractors had worked on usually do system change out as compared to simply changing the duct. This is because they know in most cases the existing ductwork was not sized well and thus very leaky. It would also turn into another serious problem and an extra expense. Starting over seems just right.

Lost home performance improvement chances
Most HVAC contractors who work around residential areas visit homes almost every day. You will find them in the basement, crawl spaces and attics where they are able to witness serious enclosure issues. For example, they encounter first hand the bad quality of the air sealing and insulation. While the professional might not know how air-sealing and insulation repairs and makeovers are done, the best complementary service they could give the homeowners is the kind of overall maintenance needed to augment the overall performance.
The ventilation in the HVAC
It is obvious that most HVAC contractors do not pay attention to ventilation in their HVAC maintenance and installation. Most new homes today are very tight due to energy codes requiring an air-sealing of a higher level. Some do not know a blower door assessment is required to confirm that air tightness has been catered for. A tight home will require mechanical ventilation whilst bathrooms and kitchens also demand spot ventilation.

The HVAC contractor needs to comprehend the three mechanical ventilation strategies of a balanced, negative and positive pressure. At the same time, having the air flow measured in all the ventilation systems being worked on is imperative.
