Protecting homes and businesses since 1950, Guardian Protection is one of the nation's largest and most highly regarded security companies. We provide smart technology, 24/7 professional monitoring, and peace of mind to hundreds of thousands of customers. Our products are installed by experts, monitored by real people, and truly make a difference. We do what we do because of one simple truth: life is better when it's safe.

"We hired Guardian to install our security system at our Washington, DC, business. The service and quality of the work was horrible. We had cameras and an alarm system installed; it was a relatively large system. They outsource most of the work to various vendors. They could not manage their vendors; what was supposed to take a week took two months. The sales rep did not return calls, and you could never get anyone in management on the phone. Random people would show up at unannounced times. The few things that an actual Guardian employee did were they made a huge mess of our newly remodeled office and were rude to our staff. We have offices in five markets across the US and have high security at each; we have never had such a poor experience."

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!"

Insulation questions, answered by experts

Yes. Proper, complete insulation will ensure that you trap the most cool or warm air inside your home, preventing high energy bills. In addition, insulation tends to settle and compress, leaving gaps over time; the more you insulate completely during the initial installation, the less you’ll need to do down the line.

At a minimum, blown-in insulation lasts 20 to 30 years. Cellulose and sheep’s wool come from natural materials, so they likely max out at around 30 years. Fiberglass and rockwool feature artificial materials that boast lengthy lifespans, up to 50 years, or even longer in some cases. As always, this timeline assumes you don’t run into any issues, such as flooding or mold, that shorten the lifespan.

The primary purpose of insulation is to maintain comfortable temperatures in a home, whether that’s cool air when it’s hot out, or warm air in winter, but that’s not all it can do. All options will also minimize heating and cooling needs, lowering both your carbon footprint and energy bills in turn. And some options, like rigid foam boards, even offer soundproofing benefits, too.

Winterization includes blowing out water, shutting off the system, and insulating exposed components to prevent freezing.

Yes, you should add an insulative cover to outdoor water spigots in the winter for better protection against freezing. Make sure to use waterproof insulating material—something like a towel or old shirt can actually make the faucet more prone to freezing when the material soaks up rain or snow.
