"I recently had a positive experience with Dunn Service regarding boiler issues, and I wanted to share my thoughts. The technician arrived promptly at the scheduled time and approached their tasks with expertise and precision, ensuring that all problems were thoroughly addressed. The pricing for their professional services was reasonable. Overall, based on my experience with Dunn Service—characterized by politeness, professionalism, and fair pricing—I would highly recommend their services to anyone facing heating and air conditioning issues."

"Project: Repair or Service a Central Air Conditioning System Sam from Liberty is GREAT! I had my AC recharged earlier this year and they charged me $170 per pound for freon!! This is the dirty little secret..You (and they) can buy it for $29 a pound on the internet....so I lost the first round with SmartHouse??? overpaid for 2 pounds plus service call plus labor.....A month later. I accidetnally cut a hole in my line in the garage.lost 5 pounbds of freon.I called all the AC companies I could find and asked them how much per pound the cheapest was $85!! some for $150!! Oh they all lie to you "the price is going up" R22 freon will be outlawed in 2020 our costs have gone up" BS! they all want to stick you for maybe an extra $600 wihtout you knowing it if you need 5 pounds. They are all con artists and liars . I checked with about 5 companies and got the cheapeast bid of $1000 ish and most around $1300! I told them I knew about the mark up on freon and they all did their little tap dance. I finally found Sam on Craigslit under services rendered...Called him he said he would give me a fixed price he knew all about the markup scam! He got the job done for $525!! Sam is a hard worker and didint show up til 7pm and had one more call that night after me! He welded my pipe vac'd the system and charged it up as good as new! While most of these AC company rackets try to get rich off of each job. Sam has a different philosophy he gives a fair deall and justs works harder than everyone else and makes it up on volume. Also he is a one man company so he has very littel overhead...One slight complaint..he hinted that he would be over by 4:15 PM but didn't make it til 7pm as he has other jobs he said were"ahead of me" I suspecet he got a job that he would lose if he didnt take it right away and could tell I would wait....Just a guess....Anyway it was worth the wait ...they say you can get Good Fast OR Cheap Pick 2. Oh and here is a warning ..If you ask for after hours service from any of the established crooked companies get ready to pay $249 a pound for freon!!!! Less"
