  • Sila is a rarity in this market – an HVAC contractor who not only knows their stuff – but actually cares about the consumer experience.  Phone inquiries are always prompt and polite; appointments are made with ease and not some ridiculous date in the far off future.

    The technicians are certified, competent, take the time to get it done thoroughly, correctly and courteously.

    Simply put they are the best in this area at what they do.  After years of putting up with rude, incompetent, and in more than one case utterly dishonest contractors, I am gratified and relieved that I can now simply leave it all to SILA.

  • Sila immediately responded to a Saturday morning call. But most importantly, the helpful technician actually tried to diagnose and help me fix the problem over the phone to save the cost of a expensive weekend visit. I was so shocked that a company would actually try to save me money! When it was obvious that it wasn’t a quick fix, he showed up exactly when he said he would. I was very pleased with the response and level of professionalism.

  • 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 !!!!!”

  • Sila did a fabulous job right from the start.  The sales person was personable and very knowledgeable. The price for the work was reasonable.  All the installers were polite and hard working people.  They made the whole instillation an easy and pleasant process.  I would recommend them to everyone.

  • Can’t say enough good things about these guys. We had no heat and logged an emergency call, since we have a 2-year old in the house. Al called back quickly – at 10:00 at night – and spent likely a total of half an hour to 45 minutes on the phone, combined with countless texts, trying to help us troubleshoot the problem so we wouldn’t have to pay extra for an overnight call.

    It turned out that we really did need a service call the next morning – our boiler is ancient and weird and, as it turned out, a serious challenge to work on. As a matter of fact, a friend who does this for a living took one look at it and told me we’d need a new one. Not Al. Nope. He was a freaking ninja. He pulled that thing apart, piece by piece, figuring our 50+ year old system out from scratch. Through the whole frustrating process, he was thoughtful about his approach, extremely respectful, and seemed to not mind the million and one questions. Thanks to Al, I now have a toasty-warm house AND a really solid understanding of how my boiler works.

  • 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.
