Glenn is old school and proud of it. He gives you a fair price and great service and backs it up. I recently had him check out my system and he said the coil was leaking freon and I was 2lbs low. He said it would cost $1200 plus freon to fix the problem. I thought I would get a second opinion and had a tech from Bell Air come over. He gave me an estimate of $2500. He said he filled the system with 2lbs for $160. I decided to get it fixed and when Glenn put in the new coil I needed 4 lbs of freon for the fill. I won't be looking for 2nd opinions again. There are a lot of flim-flam air guys out there, Glenn is a man you can trust for a fair price and the work done right.
