It is possible to conduct an annual HVAC inspection yourself but it is strongly advised to get a certified professional to do this for you, who can identify issues you could easily miss if you do not have prior experience.
The heating, ventilation, and air-conditioning system is a significant outlay for any homeowner and it is important to ensure it is working to its optimal levels and remains energy efficient. Malfunctions could also make the system unsafe and a potential fire risk.
An HVAC inspection can cost between $70-$100, which is a small price to pay for one of the most important assets in your home.
