On june 28th my ac went out completely. I called someone the next day and he tried to fix it, it lasted three hours. I knew it was time for a new one, the old one lasted 21 years. I had another unit, the same age, that was then trying o cool the upstairs and downstairs. We then called six companies for estimates. The best one was Larson air. They came out the 3rd of July and put in two new units so we had air for the 4th. They came back on the 5th and fixed the furnace as well and were here until after ten at night to make sure the job was completed. The furnace was in the attic and it was 125 degrees up there all day. They did an amazing job, cleaned up and hauled off all the old stuff and even vaccumed in the room where they were working, at 10:30 at night. The air conditioners they installed are so efficient that my electric bill was half of what it was last year at this time. I am very satisfied and the price was worth every penny.
