I know HVAC service is not a recommended DIY project but I have enough experience to be deadly and if I break it, I know I will have to pay the price to have it professionally fixed. My A/C unit stopped blowing cool air in the middle of the night during the summer heat. After a little research and testing I learned my capacitor was bad. I called up H&B Heating and Cooling and asked if they sell capacitors. Turns out they do (not as cheap as Amazon, but if you want cool air NOW, you have to pay the price). Drove to the shop to pick up the capacitor and I was even provided a few pro-tips on wiring. My A/C unit was back to blowing cool air in less than 15 minutes of returning home. Thank you H&B!!! read more
