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.

Chicago HVAC service FAQ

How can I keep my HVAC healthy with a pet at home?
One of the primary responsibilities of your HVAC system is to keep clean air flowing through your home. If you have pets, fur, dander and dirt naturally enter the air you breathe. By replacing filters regularly, having your air ducts vacuumed and cleaning and dusting regularly, you can help eliminate these allergens.
What are the benefits of having a smart thermostat?
Smart thermostats not only allow you to control the air temperature in your home remotely but also provide additional savings on your monthly bill. Chicago residents with smart thermostats save 22% on heating and cooling bills compared to those with a traditional thermostat.
When should I schedule HVAC maintenance in Chicago?
The peak of summer or dead of winter is not the time to schedule HVAC maintenance. In Chicago, it is essential to schedule an HVAC maintenance appointment months before the start of a new season. This way, you can be sure your system is equipped to handle the dramatic shift in temperatures. System checks should include an inspection of the furnaces, blower compartments and blower coils. It should also mean changing out old, dirty filters. Scheduling an in-home evaluation before you see evidence of problems is the best way to be proactive and keep your HVAC system running smoothly.
How can I keep my HVAC system safe?
Chicago sees its fair share of storms, and there are a few things you can do to keep your HVAC systems safe during these times. Turning your air conditioning off can reduce the chance that a lightning power surge ruins your system. A carbon monoxide detector is essential if you use fossil fuel. Also, make sure that there is no clutter near your furnace, as it could be a fire hazard.
What are some quick maintenance tips for HVAC units in Chicago?
Your Chicago HVAC system can last a long time if it is adequately maintained. Yearly maintenance is essential in making sure your system is running its best. Replacing and cleaning AC filters regularly and clearing the outside unit from leaves and debris can help your system run efficiently. A typical HVAC inspection includes checking the voltage and the belt condition, washing the condensing unit coils, and checking the drain line.
What’s the best indoor temperature for Chicago summers?
If you are like most Chicago families, opinions vary about the perfect indoor AC temperature setting. Many HVAC experts agree that anywhere between 73 and 79 degrees is a good indoor temperature during the hotter months. Although there may be days you want to go a few degrees lower, cranking your AC down to the 50s does not cool your home down any faster. It will probably just freeze the pipes and shut down your system altogether.
