It’s not polite to ask people their age—unless they’re children, in which case they’ll probably tell you their exact age to half a year without you having to bring it up.
You never need to worry about offending your air conditioner by asking its age. But you may not know how to go about “asking.” This can be a problem if you’re debating whether to replace the system before next summer. An AC’s age is a vital piece of info for choosing “repair vs. replace.” If you didn’t originally install the air conditioner, you may have no idea how long it’s been in your home.
We can help. Discovering the age of a cooling system is simple once you know how. (Figuring out what to do afterwards is the tricky part!)
If you’re looking for a great air filter, you need to know the term MERV. MERV is an acronym coined by the American Society of Heating, Refrigeration and Air Conditioner Engineers (ASHRAE) meaning Minimum Efficiency Reporting Value. MERV is a scale used to measure the efficiency of an air filter. Air filters are rated from 1-16. MERV might be a new term to you, but it’s routine to our knowledgeable technicians trained to get you the best 
August is often the hottest, most grueling month of the summer—and it’s a time when many air conditioning systems will start to experience malfunctions because of all the stress that’s been put on them. This is a good time to go over a list of the most common AC problems that can crop up, because this is when you’re most likely to run into one of them and have your comfort put in jeopardy!
Outlets have changed significantly over the decades. Once, homes only had two-pronged outlets. Later, three-pronged grounded outlets became the standard. Now GFCI and AFCI outlets help homes to maintain greater safety with even more powerful electrical loads.
When your air conditioning system is running during a humid summer day—and we get plenty of those in Chicagoland—you’ll occasionally hear a dripping sound coming from the unit. This isn’t because the AC uses water to help cool down the house. The only type of cooling system that does that is an evaporative cooler. What you’re hearing is the water moisture the air conditioner has drawn out of the air with the evaporator coil dripping down into a condensate pan and then being drained outside through a condensate drain line. This collection of moisture is a natural result of the evaporator coil absorbing heat from inside the house to cool the air.
The air conditioning system is just a way of life. Homes are now constructed with central air conditioning in mind, and even vintage buildings can enjoy powerful air conditioning without using window units thanks to ductless mini splits.
An overheating air conditioner is a tragic story. Your AC has only one goal: to make you feel cool and happy. Your AC will stop at nothing to achieve this, even if it means burning itself out in the process.
