One day in the future, consumers may have access to HVAC systems equipped with powerful artificial intelligence programs capable of diagnosing malfunctions early and altering homeowners to the problem—along with instructions of exactly what’s wrong and how to call a technicians to ask for help.
But we’re not quite there yet. Air conditioning systems can’t self-diagnose, but they do have ways of telling homeowners that something has gone amiss so they know to call for professional assistance. HVAC technicians use good old fashioned “organic intelligence,” i.e. their extensive training and experience, to find out what’s wrong and how to fix it. One of the ways air conditioners tell homeowners there’s a problem is unusual sounds from the system.
We may be in the height of summer here in Chicagoland, but there’s one heating system in our homes that must always work on a regular basis, day in and day out: the water heater. The water heater accounts for the largest amount of heat energy used in most homes, and that’s because it serves so many functions around the year.

This is why the condenser unit outside your house blows out heated air when the AC is working.
You’ll need to have your home’s air conditioning system running during the summer to stay cool. That’s just a basic part of Chicagoland Survival 101—our summers are hot and humid. Of course, keeping a home cool doesn’t come for free, and you can expect to see a rise in your electricity costs over the summer because of the extra use of the air conditioner.
When we’re looking into ways to help you save money on your 
We aren’t fully out of the woods yet here in Chicago as far as cool weather goes. We can anticipate days in the 50s and night sometimes in the 30s for a few more weeks. But it’s about that time of year when air conditioners will run more often, and soon the 
As we move into spring, we’re finally going to start enjoying warmer weather. But along with warmer weather comes a spike in the pollen levels. And you know what that means: allergy season! As the cold and wet weather fades, plant blooming leads to an increased pollen count, which is responsible for numerous allergic reactions that can make this season a miserable one. And pollen is only one source for allergies this time of year: mold starts to grow in the wake of the wet weather, 
It’s now officially spring, and no matter what cold spells we may encounter in the coming weeks, the move toward warmer weather has started. This is an excellent time of the year to consider options for
