HVAC reviews in Chicago, Illinois

My AC was giving out a persistent rattling sound for weeks, but I put off dealing with it until it stopped cooling altogether. When I contacted Frontline Heating & Cooling, their technician showed up promptly and walked me through what he was doing. He fixed the issue by replacing a worn-out part and gave the unit a thorough cleaning. The noise is gone now, and my house feels cooler again - no more worries about it breaking down in the heat.

My old boiler had finally given up after twenty years. Jared's team arrived, took one glance, and told me it was time for a new unit. The replacement happened the following day.

The technician fixed my noisy furnace on the spot, cleaning the burners and adjusting the blower. They arrived promptly that morning, resolving the issue quickly and effectively.

The technician diagnosed a faulty sensor causing the heat pump to blow cold air despite being set to heat mode. After replacing the sensor and testing the unit, it worked flawlessly from the start. The tech was approachable, didn't rush, and explained everything clearly. He left with a smile and I haven't had any issues since then.

We finally got around to replacing our ancient heating/cooling unit after years of constant fixes. The team showed up on time, tore everything out, and had it installed in one day. They walked us through how to use the thermostat and checked all the vents. The new system is ridiculously quiet - you can barely hear it running - and the air feels fresher.

We had a home inspection done before moving in, covering vents and ducts. The inspector highlighted older components that were still functional, giving us peace of mind about the property.

I was on the verge of desperation when our heating system gave out on one of the coldest days of the year. With two young children, staying warm wasn't an option.

They fixed it efficiently without trying to sell me a new system. I appreciated their straightforward approach and professionalism, especially given my limited time.

Purchasing a new AC unit can be overwhelming. Despite my old unit's 20-year lifespan, I was relieved to work with Frontline for this significant investment. My experience with the company far exceeded my expectations - from the initial assessment to the installation of my new unit.

Throughout the process, every interaction with Frontline's staff was professional and courteous. They took the time to explain everything clearly and provided options, ensuring I made an informed decision. The price was competitive for a high-end unit, even after checking with neighbors who had similar systems.

The level of communication and follow-up was impressive, putting my mind at ease during what could have been a stressful experience. While I hope I don't need HVAC services soon, if I do, Frontline is the first company I'll contact.

Transparent pricing and expert guidance made the whole experience hassle-free. The team were polite, swift and clearly skilled. My heating system now works perfectly.

We were in a panic when our furnace stopped working in the middle of the night, just two days after bringing home our newborn. The temperature plummeted to 55 degrees rapidly, and I couldn't get the pilot light to stay lit, no matter what I tried.

He was incredibly considerate while the baby slept, fixing the ignition switch and ensuring the vents were blowing warm air again. His professionalism and kindness are greatly appreciated during a stressful situation like this.
