Frequently Asked Questions

What should an HVAC service include?

An HVAC service should include a complete inspection of the system to identify potential problems and make sure everything is working properly. The technician should also clean the system and replace any worn or broken parts. Finally, he/she should calibrate the system to make sure it’s providing the right amount of heating or cooling.

How often should the HVAC system be serviced?

HVAC systems should be maintained at least once a year to ensure optimal performance. However, it’s recommended that the system be serviced twice a year to identify potential problems before they develop into major issues. Neglecting HVAC maintenance can lead to higher energy costs, reduced comfort, and even safety concerns.

What are 5 skills an HVAC technician should have?

An HVAC technician should have strong communication skills to relay information to customers and co-workers. They should also be able to work both independently and as part of a team.

Technical skills are important, of course, but so is the ability to problem-solve and think independently. Attention to detail is also key, as small mistakes can have a big impact on the outcome of a project. Finally, HVAC technicians should be safety conscious and always put the safety of themselves and others first.


Armed with these questions, you’ll be ready to find a qualified heating, ventilation, and air conditioning technician who can keep your home or business comfortable all year long! Don’t forget to get estimates from multiple technicians before making your final decision – and always trust your gut if something doesn’t sit right with you about a particular technician or company.
