"To start, I put in for an emergency call to Freschi and was told they would call me 30 minutes before. They never called me back. Freschi sucks!!!I I also put in a request on HomeAdvisor on Thursday night and was given Global Warming Heating and Air as one of their verified contractors. I got a call at 7am from Rudy. I called back around 830am and we made an appointment for 1130am. He showed up at 1105am and quickly diagnosed the problem. He recommended replacing the furnace(which houses the blower assembly) due to the cost of repairs and its 17 year old condition. He didn t try to up sell me for an entire new system. He said my AC is working well so there s no need to replace it. I decided to replace the furnace and he said he d be back around 130pm. Rudy and his crew were back by 1pm. From the start of demo to it running again was less than 2 hours. Rudy s customer service is top notch!! From now on, I will only be calling Global Warming Heating and Air. I can t say enough good things about Rudy s business ethics and timeliness. A+++++"

"The crew from Albert Nahman did a great job from start to finish. The project was to replace the original ductwork in our 60 year old house. Tom provided excellent advice for the estimate then Bryan’s crew did the job, 2 days, within a week of my acceptance of the proposal. Great work."
