Darius serviced my hot water heater and air conditioner today. I have used Marks previously and am very pleased with the service.
They are very efficient, knowledgeable and fair. I definitely call Marks next time. -

Giles Marks checks my A/C unit, furnace, and hot water heater every year and has been doing this for many years now. He is excellent! I trust Giles to keep the equipment in top working order and his costs are very affordable!
I highly recommend Giles!!!

Very professional, neat and organized on the job, Timely and very cost effective... I’m glad that I found their ph# and called, Giles answered my first call and arrived exactly as he said they’d be here.
