I have known Richard from Peterson Heating & Cooling for several years now, and have been using the company for probably the last five years, both at my father-in-law, and my residence. He knows what he's doing, and his crew is prompt. If there's a problem with the date and time they give, they call you ahead of time, to make sure you know what's going on. For my father-in-law, they installed a new air compressor for his a/c unit, along with reworking his furnace, in order to have a better filtering system. A few days ago, they came out to my residence when I noticed an a/c coil on my furnace was icing up. He came out and knew exactly what the problem my furnace was having. I thought the Freon was low, but turns out the filter needed to be changed. Within the hour, the furnace was running smoothly again. I have no problems with the company, and I will be using them again in the future.
