They do the air conditioner in the spring and furnace in the winter. When they call they give you an hour range and they always show in that time.

This was my 2nd experience with the company. Prior service was for plumbing work. This service was a gas furnace install. Both services were top notch, budget friendly, and professionally done in every manner. There are other projects I will definately be having done by this company.

plumber arrived on time and worked very efficiently and professionally. it was only a fitting and required no parts. I felt their fee was very moderate and fair after having used many other plumbers. I was also amazed that I had called their office and they were able to come the same day. I would definitely use them again.

It didn't go well, we are about to call someone else.

"Customer satisfaction is very important to all of us at Frank J. Klein & Sons Inc. We were unaware that there was still a problem with the shower. We were called on 9/4/13 for service due to problems with the customers shower pressure on the hot side. At that time, we removed the cartridge from the valve body, cleaned the brushes, and removed debris from the screen and ports. Once we reinstalled the cartridge, the water pressure on the hot side improved. It has been over six months since we made the repair, and this is the first time we have heard that there is still a problem. George Muszelik, President"

In March 2013 my 20 year old ac/heating system went up. I called BGand E, and Sears and F. J. Klein (the last I got
from a referral from Cummins Elec.) F.J. Klein gave me the lowest estimate, and helped me understand what would
be best to meet my needs and why. They were efficient and extremely helpful. Because they installed a system that
took special filters that were hard to get, they assured me that they would supply them to me at a nominal cost when I
needed them. True to their word, they responded immediately when I needed new filters, and the cost was less than
I would pay for smaller filters at Home Depot or Lowes. They are great. I have referred them to two of my friends who
were also extremely satisfied with their service.

I loved dealing with Frank J Klein and Sons Inc. I called to have a leaking shower fixed in my parents' home while they were away. I called on a Tuesday afternoon and got an appointment for Thursday. Matt was right on time and was great. He identified the problem almost immediately. They didn't have a needed part with them, which is understandable because the house was custom built 60 years ago, but they put me in as the first call the next morning. Matt was right on time again and had the job finished in under a half an hour. He was even able to look at a slow drain and replace the tub faucet in the process.
Everyone I dealt with was professional and friendly. The price was great. We just purchased an old house and I will absolutely call these guys for any plumbing needs that we have in the future.

"Hi. [member name removed] Thank You very much for the great review. If we can be of service to you in the future for any of your plumbing heating or cooling needs please do not hesitate to call us. I passed your complement on to Matt he was thrilled. Thank You George Muszelik President"

The serviceman (Matt B.) arrived right on time and immediately went to work.
He did a thorough check of the systems and explained to me what he was doing each step of the way. He checked the indoor systems fan blades, coils, filters ECM motors, coil temperatures with an without auxilliary heat, outdoor capacitors, fan motors, and contactors. I am probably missing something. He also provided me with a quick assessment of having a UV light installed based on my inquiry. The serviceman was courteous and knowledgeable. Overall very professional.

The Frank J. Klein and Sons - Carrier install team arrived 30 minutes early and went right to work. They began outside and dismantled the old AC unit. Chuck and Eric arrived 20 minutes later and the began on the furnace. The installers was professional, courteous and polite. They answered questions as I was eager to know certain facts about various aspects of the installation and the overall functionality of the HVAC system. The install was a long endeavor about 8.5 hours but they were proficient.

Frank J. Kline and sons is a family owned company that was also very appealing to me and they have been in business since 1929 and the are true professionals. I would certainly recommend them for anyone need HVAC service. I felt very confident that the install went fairly smooth and they cleaned up the work area superbly. One final note; I had a key in a magnetic pouch on my old AC unit and forgot to remove prior to the new install. I called George a week after the install and George found my key and promptly returned it tom me !

This is a really Great company! Highly Recommend Frank J. Klein $ Sons !

I obtained bids from three Carrier dealers -- two very large companies and Frank J. Klein and Sons, Inc., a small, family-owned company that has been in business since 1929. The proposal from Frank J. Klein and Sons, Inc. was the most competitive off the bat, although one of the large companies attempted to beat it. In the end, after speaking with both Frank J. Klein and Sons, Inc. and the other company, I ended up with nearly identical proposals for the same equipment with the same warranty. After careful consideration, I decided to support the smaller business with the long track record. I felt that if there were any problems, the owner would have to answer for them, as he was the one who personally came out to bid on the job. In the case of the other two companies, I dealt with salesmen who I expected I would never deal with again, and who would have no involvement in the installation. In addition, Frank J. Klein and Sons, Inc. provided references, and the one with whom I spoke had nothing but good things to say, having used them for years. On the day of the installation, Frank J. Klein and Sons, Inc. was prompt and had a large enough crew to do the work efficiently. The owner came out to instruct the crew on the work to be performed. I felt perfectly comfortable with every one of the employees, all of whom were courteous and respectful. They were to return the next day to test the system, which needed to charge up overnight. During the night I discovered a leak from a valve in a line that feeds the humidifier. I called the company's answering service and got a prompt return call from one of the men who performed the work. He helped diagnose the problem and got the leak under control over the phone. The next day, in addition to completing the installation of the heat pump, he replaced the leaking valve with a better one, at no additional charge. The new unit is extremely quiet and there was absolutely no debris left from the work. While it remains to be seen if the investment in the best equipment will pay off in lower utility bills and more efficient heating and cooling, I am very satisfied with the level of service I received from Frank J. Klein and Sons, Inc.

I had a good experience with them. They were prompt, courteous and neat. They didn't have the parts at first but they were quick to go and get them. They did a good job and the toilets work now.
