I called 8 different HVAC companies for quotes for a heat pump heating/ac system because I want to save money by switching from a forced air gas furnace to an electric heat pump system which will give me both heating and air conditioning. In addition my old furnace (circa 1991) was way oversized for my home and the air coming out too noisy. The New heat pump system is quieter and more efficient. Back to the quotes for the system, all the other 7 companies sent a salesperson/ advisor to give the quote. Sam, the owner of Plum HVAC came our to give the quote. He was quick with his quote and was very knowledgeable. He didn't try to upsell me on anything and have the lowest quote of them all. His price was 60% less than the highest quote and 15% lower than the next second lowest quote. I found it hard to believe that he would do a good job for an unbelievably low price (compared to 7 others) BUT Sam and His crew were fast, efficient, courteous, respectful, clean competent and just overall did a GREAT job. Sam was always easy to get ahold of and explained things in an easy way and always put me at ease. When I checked the specifications of the Heat Pump system Sam proposed and installed, the specs were better than the other quotes got. Another big bonus is I had Plum remove the old furnace from my garage and put the HVAc system in my attic and outside my house so I gained alot space in my garage. I am in real estate and have dealt with alot of trades in my time and I cannot recommend Sam and his Company Plum HVAC enough.
