  • Very professional and competent. Servicer performed the work promptly and shared his finding afterwards. No hard sell of additional services. I’d definitely use again. Highly recommended.

  • This is the second time I’ve used these guys. Courteous, quick and knowledgeable. Also, called at 7:30 am and they were here at 9:30 am…..the heat is working again and will plan to call them in the spring for maintenance on the AC unit too.

  • We had a service call from Greg M. He demonstrated such professionalism I felt I had to write and let you know. I’ve been thinking about what distinguished his visit from the service calls we get from technicians at other companies (e.g. plumbing, appliance repair). And I see three areas in which Greg particularly excelled:

    1. Greg was competent. It was clear that he knew what he was doing. He accurately and quickly diagnosed the problem. And equally quickly and competently solved it. Watching him work, I saw first hand the efficiency and ease with which he worked.

    2. Greg was personable. He smiled, maintained eye contact. He was a skilled communicator: explained the situation (i.e., what happened, how he was going to fix it), to my husband and me in easily understandable terms.

    3. He spoke well of Sila. (this is a quality I find very rare in service technicians). Since we had originally had our AC installed by Unique Indoor Comfort, I wanted to know what the transition to Sila was like. Greg spoke very highly of the company and how it treats it employees. It was clear he took pride both in his work and in his company.

    Now, all of these fine qualities would be impressive on any given day. But this visit occurred at 4:30pm on Friday afternoon, the beginning of Memorial Day weekend. And yet Greg didn’t seem rushed or resentful. He took his time, he took care to get the job done right the first time.

    Bravo, Sila, for hiring such a great employee. You should be proud that someone of Greg’s caliber is representing your company.

  • 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.

  • Jim, Just to let you know your crew that was here at Pottstown Planet Fitness, was without a doubt, the best HVAC company that I’ve ever had the pleasure of working with !They were professional, polite, and the work was exceptional. Mike was super, Jim, Matt, Sam…they were all outstanding. I can’t wait to work with Sila again. The manner and speed they did this job in was remarkable. Hats off to you guys and thanks again !!!!!”

  • I have used Sila for my heater maintenance since 2013.  All levels of the company are very professional and informative. There is no waiting around as they provide curiosity calls when technicians are running late.  Their price is competitive and I am very happy with the service I received from them and will hire again.
