Monday, July 31st, 2017

shocked-by-loud-noiseOne 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.

Why Ice Might Form on Your Air Conditioner’s Evaporator Coil

Monday, June 19th, 2017

frozen-glassIf you have some knowledge of how the modern air conditioner works, you may know it’s a refrigerant-based system, working in a similar fashion to a refrigerator. To providing cooling, both systems use chemical refrigerant to absorb heat from inside and move the heat to the outside air. This is why the condenser unit outside your house blows out heated air when the AC is working.

What neither system needs to work is ice. It’s easy to believe ice might be involved somehow—after all, the air conditioner is sending out chilled air—but it isn’t the case. Moving heat from one place to another using refrigerant doesn’t use ice. It shouldn’t create it either.

You Need to Know This about Wireless Thermostats!

Monday, May 22nd, 2017

thermostat-being-adjustedWhen we’re looking into ways to help you save money on your air conditioning in Evanston, IL or elsewhere in Chicagoland, a piece of advice we frequently offer is to upgrade the thermostat. The manual slider/dial model of thermostat is out of date, and programmable digital models have taken over.

Then there’s the current height of climate control technology, wireless and smart thermostats. These are models permitting remote access through smart phones, tablets, and computers.

No Cool Air from the AC? 4 Reasons Why!

Monday, May 8th, 2017

woman-in-front-of-fan

It’s May, and chances are that you’re already getting some use from your air conditioning system in Wilmette, IL. It may be only a few days during the week for short stretches—we aren’t fully done with the cool weather yet—but it will be enough for you to tell if something major is wrong with the air conditioner. For example, you’ll know when the air coming from room vents isn’t cool when the AC is running.

Obviously, a cooling system that doesn’t actually cool is not much use to you. It’s just acting like a big fan, and that doesn’t help when temperatures climb. There are a number of possibilities for why an air conditioner will lose its cooling power. Some are simple errors that you can correct yourself. Others are more complicated and will require HVAC technicians to diagnose and correct them. And some are serious trouble that place your AC in danger of a major failure, possibly even an early replacement, unless professionally fixed as soon as possible.
