I am really surprised to read some of the reviews. My experience with Weber & Grahn has been…read morenothing short of stellar. Even though we don't have a maintenance contract, they go out of their way to get our work done as quickly as possible, even when I'm sure they are swamped (like after holiday weekends or after storms). I have always found them to be courteous, reliable, trustworthy, knowledgeable, and not looking to sell me something I don't need. Many times I was afraid they were going to tell me I need a new system (mine is quite old), but instead they find the parts to keep the old system running, saving me countless thousands of dollars. I don't know how their prices compare to other providers in this industry, but whatever they charge is worth it. There is great comfort in knowing that when I call, they will be there as soon as possible, they will be thorough, and they will be professional.

My wife activated the…read moredehumidifier mode last week, only to find that a mildew like smell was being emitted from the unit. I called Flanders and they walked me through a simple adjustment that was an oversight on MY part, and saved me the expense of a service call.

I WOULD GIVE LESS STARS IF POSSIBLE. I have been a long term customer of Stan Gelber. They did a…read morewhole house central AC unit and a couple of split units for me. I have also recommended them to several other people for whole house installations. When Stan ran the company it was fantastic. The company has now been bought out by SERVICE EXPERTS. They are a TERRIBLE company. I have scheduled 8 appointments to fix my AC that they installed and is still under warranty and they either can't fix it or simply don't show up. John that was running the UNIONDALE office is a pathological liar and as of 4/28/26 he is fired and the UNIONDALE office has closed. All work is supposedly being handled by FLANDERS SERVICE EXPERTS in HAMPTON BAYS. This location is just as terrible. All customer service is handled by the TEXAS office. CHRIS ANDREWS is the head pathological liar at that location. No matter what he tells you DO NOT believe it. He tells you he will give you his cell # but it's worthless because he will not answer the phone or text back. It seems if the whole SERVICE experts business model is a scam, they are trying to sell maintenance contracts that they have no intention of honoring. DO YOURSELF A FAVOR AND STAY FAR AWAY FROM THIS COMPANY, THEY ARE TERRIBLE JUST READ ALL THE OTHER CURRENT REVIEWS!!

One year in these guys have been great. My old heating oil supplier was OK for over ten years, but…read morejust OK. Inattentive when I asked about possible changes and improvements. Anchor replaced dampers, tuned furnace, updated thermostats. Now better heat distribution, quieter and using less oil - each very noticable. Also big: they set me up with PROPANE tanks & supply. So we could combine suppliers and get away from the big propane company in this area which reminds me of the cable company in terms of customer "service."

Funny, we are still waiting for the other 2 firms to return our calls. Also, their bid was affordable. The staff, on the day confirmed, arrived on time, laid out floor coverings and immediately went to work removing the old system and installing the new to include installing a Honeywell Programmable Thermostat. And, upon completion, they swept clean the entire area. Now, after a few weeks, all is working well and we are extremely satisfied.

After signing to do the work and setting up the day which was on a Saturday he emailed a few days as a reminder he was coming. They arrived on time they were neet and clean during the install. The unit was tested to make sure it was running right. I would highly recommended them.

5 Stars - Honest, Quick, and Professional!…read more I had a great experience with this local HVAC company and highly recommend them. Our AC stopped working during the start of a heatwave, and Kyle was able to get out to us quickly. He was absolutely fantastic--friendly, professional, and incredibly knowledgeable. What really stood out was the honesty. Kyle diagnosed the issue fast, explained everything clearly, and made the repair without trying to upsell us on anything we didn't need. That kind of transparency and integrity is rare these days, and it's exactly why I'll be calling them again for any future HVAC needs. Thanks again to Kyle for the excellent service from start to finish!

It's a high pitched squeal. We've had Onofreo out maybe 10 times and each technician has had a different diagnosis and /or solution. Sometimes they contradict one another entirely. Onofreo just keeps coming back, making tweaks, reversing and re-reversing solutions. My only assumption is that the system has faulty parts or was installed incorrectly. It's been terrible and the ordeal has lasted for 8 months now after installation.
