Frequently Asked Questions
Q1
Is There Anything I Should Check Prior to Calling?
Before contacting GMI Mechanical for furnace repair in the Orland Park area, go through the basics. Make sure you don’t have a dead thermostat or a tripped breaker. Then, put in a new air filter and make sure you have the system set correctly. If none of these things are to blame, reach out to us for a furnace diagnostics check.
Q2
What's the Difference Between an Air Conditioner and a Heat Pump?
There's one main difference between these two pieces of cooling equipment. Unlike AC units, which need a furnace to provide year-round comfort, heat pumps can both heat and cool a home. Note, however, that they sometimes need to be paired with an electric heater in areas that see temperatures below freezing.
Q3
How Often Should I Check My Air Filters?
You'd be amazed how many HVAC problems are caused by someone forgetting to change their air filter. If you use a 1-inch disposable filter, we suggest replacing those monthly. For people with a 4-inch media filter, two changes a year is often enough.
Q4
When Should I Have My Furnace or AC Serviced?
In the Orland Park area, we recommend getting your HVAC equipment serviced before the start of each season. In other words, AC maintenance should be done at the beginning of spring, while furnace tune-ups are best done in the fall.
Q5
My AC Bills are High. Is There Something I Can Do?
Aside from replacing your air conditioner with a more efficient one, you can try installing blackout curtains, replacing old insulation, and sealing windows. Installing a ceiling or whole-house fan can also help reduce sticker shock. If you live in the Oak Lawn area, we’re happy to provide a home performance evaluation.
