Chicago heating and cooling tips
Does my AC unit need repair?
Unfortunately, many Chicago residents don't know their HVAC unit needs repairs until it is too late. This could happen in the middle of winter or during a hot Chicago summer when you need it most. Being proactive is the best way to avoid these uncomfortable and inconvenient problems. Your HVAC could need repair if you notice loud noises, weird smells and evidence of condensation around the unit.
Fix uneven cooling in your Chicago home
Uneven cooling between rooms in your house can be uncomfortable and inefficient. Some ways to fix an uneven cooling problem include having your HVAC professional inspect the air ducts for leaks. Also, having clean air filters can help. Finally, redirecting cold air through the vents may solve uneven cooling problems. Moreover, make sure to close any vents leading out to the garage. If you are heating the garage, it makes it harder to heat up the interior of the home.
How to save money on energy in Chicago
The average Chicago resident pays around $130 a month for basic utilities, including heating, cooling and electricity. Some ways to cut down on these utility bills include covering up drafty windows and doors, sealing air leaks, installing storm doors and windows and changing the filters in the furnace. Even reducing the heat on the thermostat by 1° can reduce your energy bill by 1%. Fun fact: A clockwise rotation from a ceiling fan pushes warm air back into circulation. If you run your ceiling fan in reverse, it can take as much as 10% off of your heating bills.
