Frequently Asked Questions
What should I consider when replacing my HVAC system in St. Louis?
Proper system sizing is crucial, especially with our variable climate. An oversized unit cycles on and off too frequently, wasting energy, while an undersized one struggles to keep up. Since 1971, Mertens Service has specialized in precise load calculations for St. Louis homes to ensure your new HVAC system is correctly sized for efficiency, comfort, and longevity.
My air conditioner isn't cooling well. Could it be a refrigerant leak?
Yes, a refrigerant leak is a common issue that reduces cooling power and efficiency. It's not just about adding more refrigerant—the source of the leak must be found and repaired. Our technicians are trained to perform thorough leak detection and sealed system repairs, restoring your unit's performance and preventing further damage, which is essential for our humid St. Louis summers.
Do you offer financing for a new HVAC installation?
Yes, we understand that a new HVAC system is a significant investment. To help St. Louis homeowners and businesses manage this cost, Mertens Service offers financing options for qualified customers. Established in 1971, we aim to make reliable heating and cooling solutions accessible through flexible payment plans.
