The Biggest Mistakes That HVAC Contractors Make

The Biggest Mistakes That HVAC Contractors Make

There are several mistakes that HVAC contractors make.


The first mistake is the combustion safety. There are times when the HVAC contractor is going to get a call about carbon monoxide. Therefore, they are going to check the furnace for any cracks and they don’t find anything. When this happens, they are going to say it was a false alarm and just replace the batteries in the carbon monoxide detector. But there is a chance that it was not a false alarm because they did not check the backdrafting of the combustion appliances to see if anything is happening inside of any of these appliances that could be very dangerous with everyone who is living in the home.

Air Flow

The second mistake is when they ignore the air flow. This is a very important thing when it comes to your HVAC system and there are a lot of contractors that don’t understand this. If the wrong size ductwork is used on the HVAC system, then it is going to cause a leak or inefficiency in the system. If they actually understand the airflow, then they are going to know that the ductwork is going to need to be larger than you would think they are. When the right ductwork is not used, then it could lead to a lot of problems in the future. This means that a lot more money is going to be spent in the long run.


The third mistake is that they ignore the performance of the home. This means that there might be a time when the homeowner is going to need to make upgrades to their home that is going to help with the performance of their system. Some of these upgrades might include new air sealing or installation for the home. Most of the time, they are not going to mention this because it is not going to benefit their business at all. In fact, the homeowner is going to be able to get the biggest benefit from any of these upgrades since they are going to have the opportunity to save a lot of money in the future.

Forget the V

The fourth mistake is that they forget about the ventilation inside of your furnace. But if you have a new construction home, then you don’t have to worry about this as much because the home is going to need to be built as tight as possible. This means that the professionals have to make sure that all of the air is moving throughout the space like it is suppose to. Therefore, they are going to need to measure the flow of the air to see if there is any negative or positive pressure. You want to make sure that the contractor is going to understand everything about ventilation.


The fifth mistake is that the contractors don’t think about the fact that the math problems in the HVAC is going to cause problems in the future. Therefore, the contractor will need to know how to calculate the loss of heat and gain of the heat. Of course, this is going to depend on the type of system that you have, the size of the home, and many other things involved in the home. The contractor must know that the HVAC is going to use very complex technology in order to make it work. They need to know that things are not always going to work the way that they used to especially when it comes to technology. You want to make sure that your customers are always happy.
