HVAC technicians perform a variety of duties. Their jobs may require them to use ladders, lift heavy equipment, and work in confined spaces, including inside ducts. They may also work outdoors and on roofs. This industry can be very demanding, but it offers many opportunities for those who have the right skills and training.
The first step to maintaining a healthy HVAC system is to know as much as you can about it. HVAC systems don’t quit randomly, so it’s important to know what to look for. Common signs include a fluctuating room temperature, inconsistent temperatures, and unusual noises. If you notice these symptoms, it’s best to call a professional for a thorough checkup.
One of the biggest causes of HVAC failure is clogged air filters. You should change your air filter as often as possible, especially if you have pets. If your air filter is full of dust and pet hair, your HVAC will be less effective. If your system is operating too warmly or too coldly, it’s time to change the filter.
Having a basic understanding of how HVAC systems work can make communicating problems to a tech professional easier. It can also help you make smarter purchasing decisions. HVAC contractors should have relevant certifications and experience. You should also ask them for references. You can also check out the PG&E Trade Professional Alliance to see which contractors participate in PG&E incentive programs. Finally, it’s important to compare multiple contractors’ prices before deciding on a contractor. Many contractors offer free estimates, but make sure to ask for itemized estimates so that you’ll know exactly what you’re paying for.
