Frequently Asked Questions
How often should I have my AC system serviced in Montgomery?
Most HVAC professionals recommend scheduling a tune-up once a year, ideally in the spring before the summer heat kicks in. Given how warm and humid Montgomery summers can get, having your system inspected ahead of peak season helps catch small issues before they become bigger problems. You can schedule a maintenance visit online at your convenience.
My air conditioner is running but not cooling well. What could be wrong?
There are several common causes for reduced cooling performance, including a dirty air filter, low refrigerant levels, a failing capacitor, or a coil that needs cleaning. The best way to know for sure is to have a technician run a full diagnostic. Our team serving Montgomery can assess the system and walk you through exactly what is going on before any work begins. Learn more about our AC repair and diagnostic services.
When does it make more sense to replace my AC system rather than repair it?
A general rule of thumb is to consider replacement when a system is over 10 to 15 years old and the cost of repairs is approaching or exceeding half the cost of a new unit. Older systems also tend to be far less energy efficient, which means higher utility bills every month. If you are unsure which direction makes sense for your home in Montgomery, McNally’s can give you an honest assessment with no pressure attached.
Do you offer AC services for commercial properties in the Montgomery area?
Yes, McNally’s Heating and Cooling works with both residential homeowners and commercial businesses throughout Montgomery and surrounding communities like Oswego, Aurora, and North Aurora. Whether you manage a small office or a larger commercial space, we can help keep your cooling system running efficiently all season long. Reach out or request an appointment to get started.
