  • I have used Sila twice now. First time, AC was not working because wire had been disconnected from outside compressor unit. They looked at the system and were able to diagnose why the system was not powering on 100%, fixed it, and added additional line so hopefully it won’t happen again. At no extra cost.
    Second time, and just a week later, I noticed the condensate line began to quickly drip. It was clogged. They came out same day and quickly unclogged the line. The service charge has been very reasonable especially given the same day service. Prompt, knowledgeable techs. I will definitely continue to use this company when they provide this level of service and reasonable rates. Highly recommended.

  • Sila installed a new compressor and furnace. The installers were prompt, courteous, and knowledgeable. The lead representative was knowledgeable, helpful and ensured that all aspects of the product, installation and transaction were understood. I would use Sila again and would recommend them to anyone who requires such services.

  • Wow! Sila saved me so much money and turned my heater into an instant hot box with hot air blowing with force. I thought I needed a new system and the technician came in and cleaned and put new filter in and BAM it was instantly 75 in our house! Thanks Sila for saving our family from freezing.

  • Sila installed a central air system in my home back in 2008, and now my family uses them for all of our HVAC needs. We renew Sila’s Priority Service Plan annually since it includes refrigerant and filters, unlike local competitors. My family really appreciates all of the service over the years and we will continue to work with them in the future.

  • Sila is the best! I trust no other company with my home. Sila is the type of company that makes you think, “I wish every business I dealt with was like Sila.” They installed and service my heater, ac, and generator, did my dad’s new geothermal, too. He loves there efficiency and knowledge. I love their service, punctuality, and cleanliness. Their prices are competitive, and worth the cost given their incredible business integrity. Chris is my favorite service provider. I always ask for him. He is one of many reasons Sila is the best!
