Olson Heating & Cooling Inc

None of the calculations or coordination stated in the previous review was done by Olson H&C. A casual sizing estimate resulted in an oversized unit, higher initial costs, reduced efficiency and compromised comfort. A rule of thumb duct work design resulted in poor circulation, wolfing, stuffiness and excess humidity. Further, the manufacturer (ClimateMaster) does not require its dealers to install its geothermal heat pumps according to ACCA standards to ensure the homeowner achieves the ClimateMaster touted energy efficiency and savings. In addition, the IRS relies on the "Manufacturer Certification Statement" that the product meets strict energy efficiency guidelines set by the EPA and extends the tax credit to the installation costs associated with the installed system. In such cases, the consumer pays more in lifecycle costs and the taxpayers pay more in tax credits for ENERGY STAR products that are not performance optimized. Hence, I do NOT recommend this manufacturer or dealer.

Choose only a HVAC contractor that calculates your heating and cooling needs per Air Conditioning Contractor’s Association of America (ACCA) standards and then installs the system and ductwork accordingly. Further, request the Manual J, S and D calculations in advance for both you (the homeowner) and your homebuilder. Review these calculations and the HVAC contractor’s suggested furnace location (preferably near a steel column) before signing the contract with your homebuilder. In addition, ensure the drain for the geothermal system is collocated with the system; otherwise, you will have a tripping hazard in your basement.
