A request this winter for routine furnace check up couldn't be scheduled until four weeks later. At that time also asked for an estimate for furnace replacement for which a tech was available the same day. Tech promised to send us a quote that night - the quote never arrived despite multiple requests. The tech who came out for the routine check up verified our observation that the control panel of the humidifier was not working and promised to send us a quote for replacement. Guess what - quote never arrived. We paid $205 + credit card fees for the visit but never received a statement of work or even a receipt. On the plus side the techs come out at the scheduled time, seem knowledgeable, and behave professionally. Too bad they don't have time to send out promised quotes!

Matthew replaced my Generac 8kw propane powered generator with a 24kw model. He did an excellent…read morejob. All of the extra electrical work needed was done very meticulously and the cleanup was impeccable. He did the job for several thousand dollars less than the quote I received from another Generac dealer. One reason is because the other dealer told me that my existing fuel line from the propane tank, which ran underneath a brick paver patio, was too small in diameter to supply sufficient fuel to the generator and needed to be replaced. It turned out that this was not the case. The existing fuel line has provided sufficient fuel to the generator while exercising and during several multi-hour power outages. I'm glad I got a quote from him and did not go with the first one I obtained.

The manufacturer (Briggs & Stratton home generators) suggested 3 companies for the install and Bethesda Generator was the "only" one out of the three that I could successfully contact. They were very professional and cleaned after the work was done and took the time to show me how my new generator worked. After conversing with some of the guys, to my surprise, many of the workers are retired from Washington Gas. Since my generator runs off of natural gas from my home, I find that being a plus. I just purchased an new RV that I want to store the RV in my backyard as opposed to paying for storage at a storage facility and again, I called Bethesda Generator to move the generator from its current location and once again the price was right... The glorious moment was last year when the lights were out for 3 days and I was the only one on the block with A/C in the hot summer as well as lights and a hot shower....The neighbors were lined up on my front porch asking to charge their cell phones and get out of the heat..

PLEASE take your business elsewhere as this company does not care about local families or homeowners.
