Frequently Asked Questions
How often should I have my AC system serviced in Arlington Heights?
Most HVAC professionals recommend scheduling a tune-up once a year, ideally in the spring before the hot and humid Illinois summer gets underway. Regular maintenance helps your system run more efficiently, can extend its lifespan, and gives a technician the opportunity to spot any developing issues early. Learn more about what a tune-up involves on our air conditioning services page.
My AC is running but the house is not cooling down. What could be causing that?
There are several common causes, including a dirty air filter, low refrigerant, a failing compressor, or even ductwork issues that are allowing cooled air to escape before it reaches your living spaces. The best way to find out what is happening is to have a technician perform a proper diagnostic. You can schedule a service visit with McNally’s and we will get to the bottom of it.
How do I know if I should repair or replace my air conditioner?
It depends on a few factors, including the age of the system, the cost of the repair, and how efficiently the unit has been running. As a general guideline, if your system is over 15 years old and is facing a significant repair, replacement often makes more financial sense. Our team will give you an honest assessment of both options so you can make the decision that makes the most sense for your home and budget.
Does McNally's handle AC installation for both homes and businesses in Arlington Heights?
Yes, we work with both residential homeowners and commercial property owners throughout Arlington Heights and the surrounding area. Whether you are replacing a single residential unit or need a larger commercial cooling solution, our team has the experience to handle the installation properly. Reach out or schedule a consultation to discuss your specific needs.
What should I do if my AC stops working on a hot summer day?
Start by checking your thermostat settings and making sure your air filter is not completely clogged. If everything looks normal and the system still is not running, it is time to call a professional. McNally’s offers emergency HVAC services to help Arlington Heights residents when they need assistance most.
