“Our furnace/boiler stopped working during the night.”
Our furnace/boiler stopped working during the night. Temperatures outside in single digits. We left a message with Ralph's Heating and Air Conditioning Service and they called back at 8 AM. By 10:30 AM the service provider had diagnosed and fixed the problem. I truly appreciate the honest and professional service from Ralph's. The charge was very reasonable and I like to support local business. I highly recommend Ralph's Heating and Air Conditioning.

“Unfortunately I didn’t get the 2 guys names.”
Unfortunately I didn’t get the 2 guys names. I had service at 2 different addresses, one a boiler and the other forced air. Both guys were very professional, knowledgeable and customer service friendly. They cleaned up behind themselves and answered any questions I had. I will say Ralph Heating and Cooling is a brand that represents integrity which goes a long way with me. How can you service the heart of the house without integrity? You can’t, the house is going into cardiac arrest. Take care of it and it will take care of of

“I had the pleasure of having Ralph’s repair my boiler today.”
I had the pleasure of having Ralph’s repair my boiler today. I learned about them because my dad prior to him passing away informed me that if we ever have problems with the boiler to make sure that I contacted them to take care of it and I did just that. Today I receive service that was professional from the time I made the phone call to schedule an appointment to the technician coming out and being extremely professional, and assisting me in a timely manner. The cost the phenomenal service there’s no comparison to another company that I made a mistake of calling prior to Ralph’s. I am extremely happy I signed up for the monthly service so that if something else happens to go wrong be OK I’ll feel covered. You could waste time calling around trying to get the best deal and the best service but save yourself some time and call Ralph’s and get the job done.
