If you suspect a problem with your home heating or cooling system, do you really need the services of a certified HVAC technician to fix it? After all, the do-it-yourself spirit is an American tradition for many homeowners. And, it’s true that certain household repairs and upgrades are doable for an energetic person with a few basic tools.
Heating and cooling components, however, are another matter. According to major manufacturers of furnaces and air conditioners, the list of DIY heating and cooling tasks is very short. What’s doable includes basic items like replacing the system air filter, keeping outdoor HVAC units clear of debris, updating thermostat settings, and making sure room vents are not obstructed.
Most other required repairs or service should be handled by a qualified HVAC contractor only. Here are some reasons why don’t-do-it-yourself is usually the best choice:
- It violates the warranty. The terms of most HVAC warranties specifically require that all repairs and replacements be made by a certified HVAC technician. Any DIY work done on a component under warranty may void coverage and shift all costs to the homeowner.
- It can be dangerous. A gas-fired furnace utilizes flammable natural gas, produces a very hot burner flame, and generates potentially deadly carbon monoxide gas. Certain components in a central AC, such as the system compressor, utilize a high electrical current. The system circulates refrigerant that’s designated as a toxic chemical by the Environmental Protection Agency and which requires a licensed HVAC technician to add or remove.
- You aren’t equipped. A certified technician arrives at your home with an array of very specialized tools and advanced technology that amounts to many thousands of dollars. It’s what’s required to get the job done right the first time and on time. Do-it-yourselfers are not properly equipped for this type of work and may incur additional damage — and risk additional safety hazards — if they attempt to do so.
