Recommended Customer Reviews

Our Air Condition went out and Mike came out fixed it right away. Great service and reasonable price! I would recommend them to anyone.

Great service on our air conditioner. Quick appointment and a good quote. Will definitely recommend to others.

Just want to say how great Dennis is. He fixed our water leak we were having in our front yard at the best price and with such a great work ethic. My husband had to call him back a couple times just to take care of a few little problems we had with the sprinkler system and he came and took care of it no problem. Dennis was a pleasure to work with, we need more like him. RAM Plumbing you better give this man a raise and hold on to him, he is a true gem. Thank you Dennis for everything.

Michael was awesome and efficient! Very knowledgeable and helped us learn how to maintain some things ourselves! Highly recommend!

Les came in short time after a call for leaking faucet.Job very well done in 15 minutes.Highly recommend these guys!!

We have never been disappointed using RAM Plumbing & Heating. Today our thermostat lost all power. We called RAM and they were out here within 1.5 hours, fixed the wires (that our dog ate).. w

Called RAM for a A/C and heating tune up. Mike came and was very professional. He was honest and spent time to inform me how my AC and heater system work. I would highly recommend RAM for your A/C and heater needs.

So glad I called RAM for my air conditioner issue!
Called RAM and they had a technician out the same day (actually within a couple of hours!). Michael the technician was great! Explained everything and showed me what was going on. Definitely recommend RAM for air conditioning services!

Called RAM and explained an issue we were having with our furnace and they were able to come that evening within a half hour to fix our problem. That's great customer service!

I had a troublesome main sewer line clog that's taken two attempts (so far) to clear. I've been gouged by other companies in the past, but not RAM. Each time, the technician Dennis explained the options and fees. No surprises or last minute extras. I will continue to call on them for my plumbing needs. (Hopefully not in the near future.)
Update- The sewer problem turned out to be a collapsed section of pipe. RAM got it figured out and fixed. Because they had to dig up the line, this was a costly repair. That said, the price they charged was reasonable given the nature and scope of the problem. Still five stars.
