Frequent Asked Questions

Does it make a difference if you have heating/air system cleaned regularly?

Absolutely! Your heating/air system feeds outside air into your home or building. This improves the air quality. However, if the HVAC equipment is working harder to do its job, you will reduce the overall lifespan for parts and the whole system. That means a larger bill sooner than later.

Is indoor air quality better with a clean HVAC system?

Yes. Your indoor air quality is affected by lots of factors. Your filters keep various particulates from entering your living space. They also help your heating and cooling system work more efficiently. We can recommend additional tools to make the indoor air even healthier for families that may have health issues like asthma or COPD.
