“I highly recommend Effective Air. We had a 4 year old boiler that was improperly installed by another plumber and as a result was continuously shutting down and in need of repair or replacement. Our radiant flooring needed anti-freeze and we needed a carbon filtration system due to poor water quality from our municipal water supply. Effective Air was highly recommended by Triangle Tube (our boiler manufacture) to address all our issues. EA is certified by Triangle Tube to work on their highly sophisticated boilers. Jonathan Smith (CEO/owner) personally visited our home and offered several options to fix the problems all with different price points for us to consider and work within our budget. We decided to replace the boiler and Jonathan went out of his way to work with the boiler manufacture to obtain a credit for the old boiler even though EA was not the original installer! EA’s professional technicians (Miguel and Adrian) installed a new boiler along with an anti-scald valve, anti-freeze pump and digital thermometers for the radiant floors, and a carbon filtration system. Their expert installers and technicians were clean, timely, efficient, courteous, and professional. The office staff (Janet) is equally professional and courteous and calls are returned within a reasonable time frame. Before we installed the new boiler, we used their 24 hour repair service and had a technician to our home within the hour. Overall, a top-notch company and a pleasure to have as our HVAC contractor!”

“I cannot adequately express in words how grateful I am for Brad’s immediate assessment and response. He was out to view my situation in the same morning of my initial call. Then, he was able to have our furnace and water heater pulled with such sort notice. Miguel and Adrian are angels – so polite and kind, as well as efficient and clean in their work. But more impressive was that Brad had the foresight to schedule my reinstall (when I didn’t know exactly when it’d be). This is significant because there was a >90 degree heat wave coming and he wanted to make sure we were in your scheduling books so that our air conditioning would be back in working order before the heat hit. I was so impressed and felt “taken care of” by your company. And of course, I was very pleased that Miguel and Adrian were able to come back and do the reinstall. All three men are so very nice, respectful, and conscientious in their work.”

“I am a previous customer of Laco Mechanical. Effective air took over their accounts and I couldn’t be happier. Effective Air is a great company the technician was professional, prompt and explained the problem very clearly. I will not be using anyone else for my forced air central heat/cooling needs.”

“Effective Air has been our heating and air conditioning company for years. The service is always swift, especially in times of crisis, and the work always done right the first time. The technicians are professional and friendly, and we’ve formed a good bond over time. The prices are fair, and the maintenance contracts save money and avoid headaches! We wouldn never switch our allegiance!”

-Edward of Winnetka, IL


“Knowing human nature as I do, people are more likely to communicate complaints than kudos. So I thought I’d drop you a note to say that EA’s professionalism, response, and quality.

From Brad’s initial contact and ongoing follow up through the furnace installation technicians, the work was prompt, thorough, and (to my wife’s satisfaction) clean. And I should say that brad’s attention to detail is very much appreciated.Incidentally I’ve recommended EA to a longtime friend.”
