AC condenser fan and compressor stopped operating, acting like they werent getting enough voltage. John came out right away and diagnosed it as the motor capacitor being faulty and swapped it out with a new one, and gave the condenser coils a quick wash down. He was quick, efficient, honest, and didnt try to sell me anything I didnt need, and explained everything he was doing.

There is a reason the reviews are all 5 stars. Excellent company that will not take advantage of its customers. I tried to install a new google nest thermostat, key word being tried. Long story short I blew my fuse. They came out same day, educated me on what happened and how to avoid it. Fair price, fast response time and very friendly service. Will recommend them and continue to use them in the future.

My AC stop working on a Sunday at 5pm . I called several places that claim to be 24/7 and all were unavailable. Then I ran across Apostle and gave them a call. John took my call and assured me hed be out and gave me a timeframe. He came and fixed my problem within 30 mins. He was so humble and nice . I would definitely use this company again and recommend. Trust me, when I give a 5 star review , its well deserved!!

I called John today around 2pm. My AC was acting up and it was 91 inside my house. John was able to come by and it took 10 minutes and we were back in business. This is a busy time of year for him and he was still able to get is taken care of. John is very nice, prompt and very reasonable on pricing. John and Apostle Ac/Heating will forever be my 1st choice to call.
