"Woke up this morning to my hvac leaking and contacted Markool. I have never used them before and was in a pinch. They fit me right in this morning and were out at my house within 2 hours. The tech stepped in the door and placed covers for his shoes so he did not track in any dirt which was impressive! The tech was very professional and super friendly. Problem was diagnosed and FIXED within an hour. The price was extremely reasonable to the point I was shocked in a good way (expecting a higher price). Anyways, I will most certainly be a returning customer. Thank you Markool Heating Cooling Plumbing."

"My family has been using Lyons & Sons Plumbing since the 1970s. They have always been reliable, offered fair rates on their work, and friendly. Just this week, I had a number of plumbing repairs that needed to be done in my home, including diagnosing and repairing a leak in my master bath shower. I was surprised that they were able to schedule an appointment for the next day (most contractors are so busy these days). They arrived within the time frame given, and Mark was very thorough in the work he did. He needed to purchase a couple parts to finish the repairs, and was able to come out the following day, again, within the time frame given, and finish the repairs. I am 100% pleased with their work - even after 50+ years!"

"If you don't mind spending WAY over typical rates then Peddicord is your man. They quoted a job to replace 46' of poly pipe with cvpc for $1295. They then called and said it would be an additional $990 for a total of $2285 so they changed their "fixed" rate which amounted to a rate of over $300 an hour just for labor. I protested to this crazy high rate for a plumber. He then did some calculations and said he would charge me $1460 for labor based on time on the job and $500 for materials. I then said there was no way he had $500 in material, he then said $400 and he would go no lower. So I agreed to pay the new total of $1860. I later looked up costs for cvpc and fittings, etc on Home Depot and saw where this material probably cost about $75, no where near the $400 he charged me. So he marked up his materials approximately 400% which is outrageous. I questioned him on this and he replied that he did have a list of material. I consider that being severely OVERCHARGED."
