HVAC reviews in Chicago, Illinois

Service provider demonstrated suitable expertise.

The service was completely unimpressive.

Terrible experience with their customer service, multiple times let me down. Not happy and switching to a different provider.

Avoid this company if you value a pleasant experience; their service is consistently unhelpful and unfriendly.

The service was decent, but prices varied significantly depending on the initial phone quote versus in-person purchase.

The service from this company was extremely good.

They're top-notch, but don't sell to homeowners - it's a bummer because they're the best, and I've worked hard to get good grades.

Service is quick if you arrive early, and Nick handles any job requests.

The company's management and staff consistently display a great customer-focused attitude.

The technicians were very knowledgeable and helped me locate what I was searching for despite the nameplates being worn out or obscured.

The business provided good customer service and helped me locate what I needed. Appreciated their assistance.

Good shopping experience for heating and cooling stuff - very nice staff.

Excellent service from two staff members. Highly recommended this office.

They're really slow to answer calls, especially after 4:30, leaving you waiting till closer to 5.

They're genuinely helpful and go above and beyond to assist you.

Terrible experience with this company - completely unfriendly and dismissive when I asked about availability of a specific part.

He sent me back to retrieve the necessary part and then told me they don't carry its serial number. What a complete waste of time, only to be sent on another trip for something they can't even stock.

I recently used this service and was pleased with my experience. The staff allowed me to quickly complete my task without any unnecessary delays.

Zero stars for complete disregard and rudeness.

Overpriced products, literally paying $179.99 + tax for something they could've gotten for $63.00 + tax elsewhere. Store policy prevents return, so I'm stuck. Avoid Johnston Supply altogether - not worth the hassle or extra cash.

Be extremely cautious when dealing with this company - no refunds are guaranteed. The customer service is subpar and buying online can be a costly mistake, as similar products can often be found at half the price elsewhere.
