G&S Service is good, and the installation performed on a Lennox high-efficiency furnace 3 years ago was a neat installation (far better than a prior installation by a company from Redmond WA). My beef though is with Lennox, who apparently produced a furnace with a defective design on a pressure switch, necessitating a replacement within 3 years of the new furnace installation. It is apparently a known issue with thousands of premature switch failures. Okay, I expect some issues after 10-15 years, but at 3 years, a brand-new unit should still be performing flawlessly, especially on a furnace that has been professionally serviced annually by G&S. Despite purchase of an extended service plan (about $150 per year - even when combined with a service visit!) - this repair cost $140 for the technician time (total of just over $300 with tax on a 3 year old furnace for an annual inspection/cleaning + the pressure switch repair. Too much maintenance cost for a nearly new unit in my opinion. Not a fault of G&S particularly, but of Lennox!
