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!"

Energy Efficiency Auditing questions, answered by experts

Blower door tests are measured in a few different ways, but the most popular are air changes per hour (ACH) and cubic feet of air (CFM) moving through the house per hour. A good ACH score is less than 2ACH, but 1ACH is better. This means the house experiences a total air change within 60 minutes (for 1ACH). For 2ACH, there’s a complete change every 30 minutes, and so on. CFM scores are similar in that a lower score means less air change, and therefore less leakage.

Smart glass doesn’t use a lot of electricity, and you can expect a standard window to add between $1 and $2 per year to your electric bills. Smart glass is proof that energy-efficient windows work. Although your smart windows may consume a little energy to operate, they can save enough energy to offset the costs. If you’re concerned about the minimal bump to your electricity consumption, you can opt for smart tint, which doesn’t require electricity to work.

Depending on the level of audit you choose, a home energy audit will at least include a walk-through of the home to determine visible inefficiencies, but may include testing and a highly detailed inspection and report laying out the home’s inefficiencies and providing recommendations to fix those issues. The audit may also include a review of utility bills and mechanical testing. Consult your home energy auditor about the types of services they provide before hiring.

You can check your home's humidity in a few ways. A simple option is to use a hygrometer, which you can find at a hardware or big box store. Your smartphone may also have an app that can measure humidity. Modern thermostats, particularly smart thermostats, are also able to measure humidity levels.

While many states require all new construction to undergo blower door tests, it’s not a requirement for existing homes. But in both cases, a blower test helps confirm that the contractor has sealed the exterior, that the type of ductwork installed is functioning properly, and that your home is as efficient as possible.
