"Ben, the owner, came to our home for a total evaluation of how we might improve comfort and save energy. The focus and area of most concern was the basement, where air leakage was causing some first-floor rooms to feel colder than others. Kyle and John spent roughly seven hours using spray foam at accessible rim joists, lining the walls of the crawl space, and adding insulation to two exterior doors. Since it has been only a week, we don't know if we will see monetary saving, but we are pleased that our first level floors no longer have the cold spots. The guys were pleasant, kept us informed throughout the day, and showed us what had been done before they left. Thank you Home Energy & Comfort!"

For 20 years, ECI Comfort has been designing and installing high-efficiency HVAC systems throughout Bucks County and the surrounding areas. Through our work with Unico and Mitsubishi products, we are able to install high-performance, high-velocity systems in a variety of homes, specializing in those that do not or cannot encompass conventional ductwork. We also service and replace all makes and models of HVAC equipment, deliver home heating oil, install generators and perform energy assessments. Additional contact name - Chase Musser. Additional email - [email protected].

"ECI Comfort replaced our heat pump, which included the outside unit, inside air handler, and thermostat/control, in April of 2020. We paid competitive pricing. Our Trane system is still working like new! During our first regular servicing of the unit, the technician, Selinda Killing, found our Air Scrubber (a device to clean the air as it passes through the Air Handler) not working. That item was added to the Air Handler, free of charge, during installation. Today, the Ultra-Violet Bulb, which is the piece that does the actual cleaning in that Air Scrubber, was replaced by technician Mike Slawecki. That is working well, again! Ms Killing, Mr Slawecki, as well as the entire installation crew, in 2020, were totally professional and polite. Our Air Handler is in our attic, with not-easy-access in the master bedroom walk-in closet. The entry to the attic is 18" X 48", and everyone has handled that very small area without issue. Removing the replaced components, as well as, bringing in the new components, through that opening, was not easy. My wife and I have been quite pleased with all ECI has done for us. ECI Comfort is a first-class operation, and we would recommend them for all of your HVAC needs!"

I began working in the construction industry by my father’s side more than 20 ago. I had the privilege of learning from the regions best craftsmen... Professionals who took pride in their work and cared for their customers. My father worked with men that shared his impeccable standards, integrity and drive to do the job the right way every single time the FIRST time. While they taught me the trades, my father shared with me everything he could about business, instilling in me a strong work ethic and a set of core values that will never, ever change. I branched out on my own and opened ceccola construction 16 years ago. I believe our success continues year after year because of our integrity, craftsmanship, and my enthusiasm toward my work. It is very rewarding to me to know that my clients are so happy that they refer me to their friends and family over and over and over. Although the construction industry has changed quite a bit since I pounded my first nail, the way you should be treated has not. We have all the new gadgets, tools and materials, but most importantly, we will always treat you with respect and care.

"They did everything I wanted perfectly. All employees are experts and are very professional. Christian worked hard to give me the most beautiful deck possible at an affordable price. Justin has the best design skills I've known. They were mindful of the water source knob even thought I didn't ask them, and I am very grateful for it. I wholeheartedly recommend this company."

"Facts: contacted company to schedule service. Two weeks before electrician would arrive. Electricians arrived on time. Review electrical problems with technicians (two showed up). Left electricians to survey the home's electrical system. Met with electricians about current immediate problem. Agreed that the state of the system required someone specializing in old homes with legacy electrical wiring. Technicians informed me they had someone on staff who could survey the home and provide solutions to remedy the existing problem and possible overhaul of the system. They said they would escalate the problem to the appropriate person. I asked when is a reasonable time to wait before hearing back from the company. They said by the end of the week. I asked again how long to hear back - thinking that the end of the week was optimistic since it took them two weeks to get to the house. They said again by the end of the week. I waited until the following Wednesday and after not hearing anything from them left a review on the company website. Later that day a manager contacted me to discuss my review. NOT to discuss the possibility of getting someone out to the house but specifically the review. He stated a technician called me the day after the technicians were at the house. I have a smartphone they record ALL incoming and outgoing phone numbers. NO number from anyone I didn't know showed up in the phone log. NONE. And if he had called and received no answer NO one from the office bothered to follow up either by phone or by email or by text message. To the people at Oliver, welcome to the 21-century. How about using some the technology available to you for something besides swiping my credit card for the "arrival fee". DO NOT HIRE this company for ANYTHING! And BTW, another company I contacted for the same issue has sent me three text messages to follow up on the appointment that hasn't even happened yet. And I didn't have to wait two weeks to get on the schedule. Oliver, take a hint!"
