| Laurie Rheem makes nice furnaces. However, I would never recommend purchasing HVAC through any big box store program. The characterization of your basement always being cold usually is an indication of poor ductwork design/sizing, insulation qualities. Basements at or partially below grade have low heat loss properties. Dealer should That furnace will require a two stg thermostat for full functionality and best operation. You need to find out mdl thermostat quoted. I do recommend a good 4-5" box filter media cabinet. If you are dissatisfied with pricing, then shop around. IMO |

| Thank you so much for your thoughts. I was referred to the dealer from Home Depot, but the dealer is an independently owned company in business since 1952. No complaints with BBB. Does that make any difference? Should I keep looking? The basement is partially below ground and has a finished family room. As you say, it might be poor duct work or insulation. What can be done short of ripping walls apart? The media cabinet requires expensive filters a couple times a year. What is the advantage of a media cabinet? I read the Rheem Web page. I still feel lost. Any help is appreciated. |

| The HVAC contractor is obligated to pay a certain percentage to Home Depot. You are either going to pay a higher price, or the contractor may cut corners on the installation to make up the difference. You should get three quotes to compare costs and recommendations of contractors. Ask the dealer to measure your duct work to determine if the size is sufficient. You may not need to open up walls. A 4 inch filter lasts 3-4 times longer than a 1 inch filter. So it is not costing more money for filter replacement. In addition the 4 inch filter has less air resistance than the 1 inch filter. This will improve air flow. Who told you your 25 year old furnace is 60% efficent? Furnaces of that vintage usually have 75-78% efficiency ratings. |
