5 Mistakes HVAC Contractors Make

5 Mistakes HVAC Contractors Make

Looking to hire a reliable HVAC contractor? People make mistakes, we all know, though some mistakes can have a much greater impact on others than some mistakes. Heating and air conditioning contractors are no exception, the can make mistakes that can hinder the performance of HVAC systems when they are installed. These kinds of mistakes can affect their customers and it can make mistakes that hurt their business as well. Look out and be aware of these 5  mistakes HVAC contractors make:

  1. Not understanding combustion safety

When an HVAC contractor responds to a carbon monoxide call, most go automatically to the furnace and look for any cracks in the heat exchanger. If they find that there are no fractures, most assume that there is no danger, so they simply change the batteries in the CO alarm and don’t think twice about it.

A common mistake many HVAC contractors make is they not knowing much about back-drafting of combustion appliances. Nor do they test for it. If you’re an HVAC contractor and not testing for flue gases and worst-case depressurization on these calls, you’re leaving a potentially dangerous situation. You never want to find out the next day that the people in the house you just visited are in the hospital with CO poisoning.

  1. Forgetting the V in HVAC

New homes are tighter than ever because of energy codes that require higher levels of air-sealing and in some cases, blower door tests to verify the airtightness. Tight homes need mechanical ventilation. All homes need spot ventilation in kitchens and bathrooms.

  1. Skipping the math

Heating and cooling systems aren’t the same as they were 50 years ago. Nor are homes. Rules of thumb don’t work because every house is different. If you want to size a system properly, you’ve got to come up with some way of getting at the rate of heat loss and heat gain in the home you’re working on. HVAC systems are complex technology. If you’re relying on rules of thumb or doing things the way you’ve always done them, then you’re not serving your customers well.

  1. Trying to be the low bidder

When contractors try to get low-bid work, they have to keep all their costs as low as possible. They hire poorly trained techs and they don’t do enough—or anything—to get them trained properly and keep them updated. They use equipment that won’t last. They do the least work they possibly can on the distribution system. This is no way to run a business. Because there are so many companies willing to do this, though, there will always be room for smart contractors to come in and do things right. Yes, everyone wants the cheapest price they can get, but that doesn’t mean that they want cheap work that they can’t rely on.

  1. Failure to use house-as-a-system thinking

Experienced HVAC contractors and HOA managers know how to listen to homeowners and troubleshoot the source of the problem. For example, an HVAC contractor can ask if allergies have been flaring up with the occupants. If so that can be an indicator that there may be an issue with the air filters.
