When you need AC heating or plumbing services, look no further than Horizon Services. For nearly 30 years, we’ve been the trusted name in plumbing heating, and air conditioning, offering an unmatched level of service at reasonable rates.

"Less than 5 years ago, I spent in excess of $10,000 to have a new unit installed with a 10 year warranty. I should have seen the red flags from the very beginning. The sales representative told us additional vents would be installed and when the installation crew showed up, that did not happen. Fast forward to the present and I am now on my 4th phone call for an appointment this season, 3 days so far of not being able to work as I waited for a technician to come diagnose the problem. The 3rd. tech came last night and indicated that the work the other tech did was not for the root of the problem. (I was told in front of witnesses that the work needed to be done, was not covered under warranty, would cost me $367 and would fix my issues)In fact, the 3rd tech only made the issue worse by leaving our attic return unscrewed and overfilling our unit with Freon that the 4th tech had to remove from our system. Upon leaving last night I was told that everything was corrected. Today - my home is slowly creeping up in temperature (presently 80 degrees inside, while set to 72). The company keeps trying to sell me a "maintenance plan" and I keep reiterating to EVERY one who pushes it that we have been getting tune ups/cleanings elsewhere and will only use them for warranty issues since we have had NOTHING but problems with them."

My name is Patsy Cicala Jr., I am the recipient of the Super Service Award for 2016 -2022 from Angie's List. BEST WAY TO GET IN TOUCH IS pcicala1@gmail.com, or call 302-245-5606. I retired here 11 years ago in Sussex County after a rewarding career in the field of Environmental Science and General Contracting in upstate New York. When you retire, you should have an exit plan.... I, however, am finding sitting down to read a book or taking a long stroll on the beach will result in either me being placed in a mental institution, or being shot by my wife (she says I am driving her crazy). Therefore, after renovating three homes in the area, I have decided to offer my services as a handyman. My wife says that I can do small repairs including bathrooms, kitchens, and small additions, porches and decks, Check out my Photo Gallery to see if I can fulfill your needs

"I was very pleased with Something Constructive. Patsy is a great guy, very personable, and you quickly feel like family. He is creative, has a keen eye, and is a great problem solver. He and his crew are great – so pleasant and respectful. I actually enjoyed seeing them each day! They work together well, are meticulous – the work quality is excellent, and they were very neat. My neighbors were very impressed with how nicely they maintained the area while working. Patsy and his crew stayed on schedule and he is really good at keeping you posted along the way. I highly recommend!!!"

FAQs for central humidifier installation and replacement projects in Dover, DE

Aim for indoor humidity between 30% and 50%, with the sweet spot around 45%. That range keeps mold, dust mites, and musty odors in check while protecting drywall and woodwork. Staying in the zone also helps your HVAC system run more efficiently and supports healthier air for you and your family year-round, during hot summers and cold winter months.

With routine filter changes and coil cleanings, most whole-house units run for eight to 15 years. Heavy use, poor air quality, or bargain-bin equipment can shorten that span, while a well-maintained, high-quality model often makes it to the upper end of the range. Ask your installer about recommended service intervals to get the most mileage from your investment.

It depends on your climate. Homes in cold, dry regions can often shut the dehumidifier off once winter sets in. If you live in a warm, humid area—or your house tends to trap moisture—you may need to keep it running year-round. Use a simple hygrometer: if readings stay below 50%, give the unit a rest. Just remember to restart it when humidity climbs again to avoid mold and condensation.

Dry air feels cooler, so your AC doesn’t have to work as hard. By stripping out excess moisture, the dehumidifier lets you raise the thermostat a few degrees without losing comfort. A shorter AC runtime reduces electricity use and can shave a noticeable amount off your summer power bill. Energy-efficient models further enhance those savings.

If your home is under about 2,000 square feet, a well-placed portable unit can handle the load. Just remember they’re less efficient and need hands-on upkeep—think emptying tanks and cleaning filters. If you prefer set-and-forget convenience or plan to expand your living space, a whole-house model still offers better long-term comfort and lower energy use per square foot.
