Geist Heating & Air Conditioning - Maryville's Qualified HVAC Services

In Maryville's climate, with seasonal pollen, dust, and debris, we recommend having your condenser coils professionally cleaned at least once a year, ideally in the spring before heavy AC use. Dirty coils are a common local issue that forces your system to work harder, reducing efficiency and increasing wear. Our maintenance service includes a thorough coil cleaning to restore proper airflow and cooling capacity.

For most Maryville homes, a pleated filter with a MERV rating of 8-11 offers a good balance of airflow and particle capture, helping to prevent the clogs that strain your system. We advise checking filters monthly and replacing them at least every 90 days, or more often during peak allergy seasons. During a service visit, we can assess your specific needs and recommend the optimal filter for your HVAC system and indoor air quality.

Absolutely. Many major repairs start with neglected small issues like the dirty coils and clogged filters common in our area. Our preventative maintenance plan is designed to catch these problems early. We perform a comprehensive check, cleaning critical components and ensuring everything operates efficiently. This proactive approach helps Maryville homeowners avoid unexpected breakdowns during extreme weather, extends system life, and maintains consistent home comfort.
