Recommended Customer Reviews
Sarah H.Just called this place and the lady was very nice and extra helpful. They did not provide the services I needed, but they gave me some great ideas.
We hired Frederick and sons to come out and do several projects at our home which we were remodeling. First, I completely agree with the other reviewer that Leonard, the father, is incredibly rude. However, Levi the son, is very pleasant and nice to work with. Our project was fairly large... We needed pipes moved, we needed a drain created for a bathtub that we converted to shower, a bath tub installed along with several other projects. We ended up having to have them come back because the drain they installed for the shower sat above the ground 2 inches and the drain they installed for the bath tub, was broken, dirty and banged up. Considering all the work they had done we thought these were just a small oversight and they did come back and fix them.
Fast forward to today. I had them scheduled to come out and install the plumbing for the kitchen sink, the bathroom sinks, install the dishwasher and the gas cooktop. They came out and there was an issue with the bathroom faucets. They called me and told me what the issue was and I immediately got on the phone and was trying to rectify the situation. I asked them if they could just move onto the kitchen sink, dishwasher and cooktop since we were planning on moving into the house tomorrow.
A half hour later I get a call from Leonard who advises me that he has pulled his workers from the job, that he doesn't want to deal with the hassle of the bathroom sinks and that they are gone and not coming back. I was completely shocked and told him that he did not need to do the bathroom faucets but could they please finish the rest of the work that they were there to do. He refused saying he wanted nothing to do with this job and would not be returning.
So now here we are moving into the house tomorrow, scheduled to have 25 people over to our house for Easter on Sunday and I have no cooktop, no dishwasher, and no faucets anywhere in my house. I am scrambling to find another plumber to come in and do the work that I scheduled with him over a week ago. I have never in my life seen such terrible customer service. To leave a person in a situation like this is ridiculous. I understand that the bathroom faucets wouldn't work and I told them it was fine, I would figure out another solution for the bathroom faucets but I asked them if they could please finish the rest of the work that I had hired them to do and they refused. I would never, ever recommend this company to anyone. The owner has absolutely no regard for his customers, would not hesitate to leave you in a bind and is an overall unpleasant person to deal with.
Frederick and Sons saved our vacation! At 10 p.m. on the night before we were scheduled to leave on our trip, I turned on our 12-year old Trane air conditioner to discover that it was not blowing cold air and the outside unit was making a terrible noise. I immediately turned it off and started calling 24/7 HVAC companies. The places that did answer the phone couldn't make it out until later the following day. I even spoke to one owner who seemed annoyed that I would call so late, despite their site advertising 24/7 service. Finally found a company who gave us a window of 10-1 the following day. Those several hours would have put us way behind schedule, so I started calling more places the next morning.
At about 7:30 a.m., I called Frederick & Sons and spoke to Leonard. He said he had a couple of techs nearby and would get them to our house by 9 a.m.. He said he'd call me right back to confirm. Honestly, I was skeptical after all the no-goes and broad time windows from the other companies. Leonard was true to his word and called back shortly to say he could get someone here in 30 minutes. Manuel and Matt arrived even faster than promised and were here around 8:15 a.m., so I cancelled the later appt with the other company.
Oh, happy day! Manuel and Matt replaced the capacitor, tested the unit, and the angels sang (i.e., I heard strong, cool air blowing). They told me they confirmed that the capacitor was bad and that they had to install it to check the system. They said everything else looked good. Manuel and Matt were friendly and professional, and took care of the problem quickly.
What I really appreciated was that they told me if I didn't want to pay for the capacitor, I was not obliged to keep it (they had to install it to test it, but would remove it and just charge for the service call). With the age of the A/C, they could easily have told me it was a much bigger problem, and I would have had no way of knowing if they were telling the truth. Of course, I gladly paid for the capacitor and the service, and I believe the price was reasonable and fair.
I will not hesitate to contact Frederick and Sons for HVAC/plumbing needs in the future!
Katrina A.Great service! They always do an awesome job. 2 yrs replaced my AC. Best price! And quick.
Last week a plumbing leak. Called and came right over and fixed leak and tightened a leaky shower Thanks guys.
You are the Allen family go to for all our plumbing and HVAC needs!!!
My first Yelp review! Because they deserve it! Most plumbing companies I called wanted to do a visual estimate first. Frederick & Sons was recommended to me by a friend. I called and spoke with Levi and he gave me price estimates for each of the work I want done (Pressure vacuum breaker installation, shut off valves replacement, hose bibs replacement, etc.). Price was also cheaper compared to a quote from another company.
Manuel did the service at my house. He arrived early and was very nice. I can say that he did an awesome job. I didn't get charged extra for his trip to Home Depot to get additional parts needed for my house. It took him 3 hours to finish all the work, and the best part is, the price was right on the dot with the estimate I got over the phone, plus some discounts!
I would definitely hire them again for future plumbing needs!
Dan D.We had an emergency plumbing issue and our home warranty couldn't find us anyone to come on a Sunday. We had no water and couldn't shower, etc. I looked up plumbers on Yelp who were open today and they popped up with 5 stars! I called and they answered right away! They were to our house within 30 mins too. Landon and Manuel were very nice and did a fantastic job explaining everything. I would recommend them again 100%! Thanks guys!
I was having a problem after changing out an old thermostat for a new. I couldn't get any power to the new thermostat. I checked everything, GFIs, outlets, ect. After two days without heat, I called Leonard at Fredrick and Sons. He told me that I had touched two wires together and had blown a three amp fuse in the unit. It worked. I called him back to see if I owed him any $$$$$$. He said it was his pleasure to help. WOW. I will use them from now on!
John C.Just moved in to our new house and we needed some plumbing done. The two young men that came to do the work were very professional and courteous. We were given a very fair price for the work done, they did a great job and it was quick too. I will use Frederick and Sons for any of my future plumbing and AC needs. I highly recommend them!
Eric S.Best service and pricing in the area. Called with a problem and a truck was here within 30 mins. The plumber was knowledgeable and professional. This is the second time I've used them and will continue using Frederick and Son exclusively
Trenna R.These guys easily earned their 5 stars!
Sunday evening on Labor Day weekend our AC decided it didn't feel like working anymore... great.
We called F&S and they came out within 30 minutes.
They charged us no bs Labor Day fee, weekend fee, rush fee, etc.
Quickly diagnosed the problem and had the air blowing within an hour. We were so concerned about our dogs in the house and I don't think they ever even noticed!
Very affordable and well worth it! We will continue to use this company and gladly refer them!
