Kling F F & Sons

Recently moved into a house about 6 months ago, and my furnace was working great. Ran air conditioning for 2 months without a problem. All of a sudden, my unit stopped cooling as well, so I called FF Kling to come out and diagnose the issue.
They sent out a young man who told us that our air conditioner had the old style freon, and that we needed to replace the unit and it would be around $ 5000. It did not have the old style freon.
I called the next day, and they sent out another tech who told us it was the AC unit and the furnace. The man then told me it would cost about $ 8000-​$ 10,000 to replace both units.
I finally called another company, and they charged my AC unit and repaired the issue in about 30 minutes. What should have been a $ 300 repair, would have cost me an arm and a leg because FF Kling is completely dishonest.
I left a message with the owner of the company to return my call, and after 3 days, I never got my call returned. I called again today, and the secretary told me the owner got my message and he would call me next week. I asked politely to speak with the owner now, and he refused to speak with me.
As a small business owner, I know that customer service and honesty is what separates a great company from a bad one. Kling has proven they are a terrible company.

I’ve used FF Kling & Sons three times now. The first two times were for a general cleaning of my heating unit, then again for my air conditioning unit. Today, I used them for a plumbing problem in my bathroom sink.
Each time, I’ve gotten prompt response from the person who answers the phone, and the technicians I’ve gotten to do the service calls have been polite, considerate and have done a good job. The technicians have also been very good about explaining what they did and cleaning up after themselves (especially with the plumbing, which was VERY messy – but Michael did a good job cleaning it up). Each time, the technicians have been there when they said they would, and even called beforehand to let me know they were on their way.
I can’t speak at to price (since I don’t have anything to compare it to), but as an example, to have my bathroom drain unclogged (which meant the technician took apart the drains under the sink – since we’d already tried to clear those lines ourselves and we knew the clog wasn’t there – used a heavy-​duty snake to unclog the drain, then carefully put back all the lines and checked to make sure they weren’t leaking, then cleaned up his mess), it cost $ 69 for the service call, plus $ 89 for the technician’s time. He was finished in less than 30 minutes. (Did I mention I called that morning, and the technician came the same day?)
Overall, I’m very happy with the work done by the technicians at Kling & Sons and will keep them on my list of local businesses that I’ll continue to do business with.
