Had Custom Air replace my HVAC system this summer with a new furnace and AC. I originally was set to go high efficiency but after getting quotes from Logan / Worthington Air / Custom Air, 2/3 recommended against it. Worthington air was the most thorough for the estimate and inspection of the home. However, Pete from Custom Air came to the same conclusion as Worthington Air in 1/2 the time. Both vendors recommended increasing size of cold air return to maximize system efficiency. Senior engineer, by trade, I tracked previous years of usage and calculated ROI of 90% AFUE system to be 8-9 years. My previous 80% Trane system lasted 27 years. Well beyond its expected service life. The goal is least cost, low maintenance, keep it simple stupid. The 90% systems try to capture every ounce of energy meaning instead of allowing warm moist air to escape, the air condenses inside furnace and then it is about expelling condensation either outside or to drain. My take-away is the 90% systems sounds great but any hiccup in the first 8 years negates any potential savings. This winter has been especially cold, happy to say my new Trane system has been operating flawlessly. I planned to pay more for high-efficiency system but Custom Air sold me what I needed with a take it or leave it, here are the facts and their expert experience help drive decision. 6 months in since install. Still very happy with entire process from quote, install, and long term review of services.
