We contacted George's upon the recommendation of a friend after another company had inspected our heat pump system and gave extremely high estimates for maintaining existing system and for replacement. Note: our system had not broken down and was still cooling our house, but not in an optimal way. George's came out promptly and added 3 lbs of refrigerant ($30/lb vs. $70/lb) and repaired loose insulation for a total cost of $200 vs. $1500 quoted by the other company. They indicated that our system would probably have to be replaced in 1-2 years and estimated that they could install a good system for $9,000 vs. $14,000 - $22,000, quoted by the other company, for our 1900 sq ft, single-story dwelling. Yes...we will be contacting George's when the time comes to replace our heat pump system!
