Very professional group to work with. So hard these days to seek help in fields/services one might not know about. When help was needed, these are the right folks to work with. They tell you what they can do, they taught me something new along the way and they gave me written proposal for the job. Most importantly they took pride in their work. Worked diligently and resolved the project in the shortest time possible. Their job cleanup was impeccable. Additionally, they stand behind their methods and products should you need any followup. 🌟🌟🌟🌟🌟

We have Frederick take care of church boiler and manse. Always willing to work around our schedules ,have great performance and prices.

Great company to deal with I will not use anyone else. They are fast and efficient and have a great prices

Got on site quickly. Isolated the problem quickly, had parts on hand to repair the issues and fixed the problems. Reasonably priced and great service. Will use them for all my heating and cooling needs.

I used them twice, once for a heating issue, the other for central air/thermostat problem. I HIGHLY recommend them. They are kind, polite, professional, and reasonably priced. Great prices and great service... what more could you want?

These guys are the best. They had a tech to my house the same day I called in the middle of winter. He took time to show me what was wrong and explain his recommendation. The owner, Mark, came to my house personally the next day to deliver the estimate. Best hvac company in the area

Very happy with Frederick and Son has always been there when we need themGood service

After speaking with their journeyman plumber, and sending over sewer camera videos of a potential replacement, I could not get a call back. Based on the lack of response, would you consider hiring a contractor that cannot simply provide a courtesy of a return a call to say that they are either too busy to take my job or not interested? That speaks volumes to their level of customer service.

They are extremely over pricing their jobs. Be ware they priced a job for me at 2400. I was able to get the job done for 800. Chase was extremely nice but Im not paying 3 times the amount for him being a nice guy. That must be a trick to get business. Also I put in a request from home advisor and they called me three times before 8 am. 7 am, 724 am 745 am , people are sleeping. Must not be that busy because his prices are ridiculous.

Cant recommend Frederick hearing and cooling enough! These guys are great. Very fair prices, reliable, and trust worthy. My AC went out on a very hot Friday afternoon and mark was out there the next morning at 9am. I cant say enough good things about this company. You would be wasting your time and money if you went anywhere else for your heating and cooling needs.

We contacted Frederick & Son for a time-sensitive sewer line issue. We based our call to them on the stellar reviews on Home Advisor. They requested that we send the video from the inspection over and and stated that the master plumber would be in touch ASAP. We were NEVER contacted. We tried several times to follow-up, but again, did not hear from a plumber. I would have understood if the business was too busy to accept a job, however, this should have been stated. (if not immediately, on a subsequent call) This job had the potential to upwards of 10k, but there was no interest. I find this very unprofessional and I am extremely disappointed in the company and in Home Advisor, as I have received other fantastic contractors from the site.
