Horizon Services is the region’s largest and most well respected plumbing, heating and air conditioning company, with nearly 600 employees serving tens of thousands of homeowners throughout Delaware, Southeastern Pennsylvania, Southern New Jersey, and Northeastern Maryland. After a quarter of a century in business, Horizon Services remains fully committed to setting the industry standard for customer service, installation, and focusing on things that are important to busy homeowners: respect for their time, their home and their property; up-front pricing, and an unconditional 100% money back guarantee. Horizon Services is the Heating Company Your Friends and Neighbors Call to Keep Warm All Winter Long!
"I had a very negative and unprofessional experience with Horizon Services. I signed a contract with them. When it was time to service my AC unit, they cancelled my appointment and rescheduled it, only to cancel and reschedule it again, and yet they did it again! They cancelled my AC maintenance appointment three times over nearly a month period. The scheduler kept cancelling the appointment a few minutes before the appointment time, which was very inconvenient for me because I had to be home every time they scheduled. After the third cancellation, I asked the scheduler to escalate the case to a supervisor which he told me he did. But the Horizon customer service manager never called me back. I called again and escalated again, still the Horizon customer service manager never called me back. I called at least twice after that and was told that my case was already escalated to a female manager, but still she never called me back. All I got from the Horizon phone operators was repeated empty promises that “someone will call you back in 12 hours, etc.” But they never called back to commit to either providing the AC maintenance service or cancelling my contract and refunding my money in full. What makes matters worse is that none of the Horizon Services phone operators who answered my repeated calls was able to transfer me to a manager to speak with in real time. These operators said that they could only “email the senior manager or the concern department”. What a disappointment, and what a lousy excuse to ignore a contracted customer. I truly regret hiring Horizon Service and signing a contract with them and I will never recommend them to anyone. The failure by Horizon Services to provide the AC maintenance per the contractual agreement (it’s now mid-summer and my aging AC unit was not serviced to date) and the fact that their customer service manager never bothered to respond to my repeated phone complaints speak volumes about the unprofessional way they have treated me."

"A Raving Review for Green Mechanical LLC! If you’re looking for the absolute best HVAC service around, look no further than Green Mechanical LLC! This company is truly a gem, and I couldn’t be more thrilled with the incredible service they provided. My heater had been misdiagnosed by another company, leaving my family and me in the cold—literally! Thankfully, I called Green Mechanical LLC, and they completely turned things around. From the moment I called, I knew I was in good hands. Devin Green, the owner himself, came to my house to personally assess the issue. This level of dedication and care is something you just don’t see every day! Devin’s professionalism, deep expertise, and genuine commitment to solving the problem made all the difference. He didn’t just slap on a temporary fix or rush through the job—he made sure to thoroughly diagnose the issue and explain every step of the process to me. A huge shoutout to Jacob and G, who also worked on my system. They were punctual, knowledgeable, and incredibly respectful of my home. Their teamwork and attention to detail were top-notch, and it was clear they take immense pride in their work. Thanks to Devin, Jacob, and G, my heater is now working perfectly, and my family can finally enjoy a warm, comfortable home again! I also want to emphasize how important it is to support small businesses like Green Mechanical LLC. These are the companies that truly care about their customers and their communities. Devin and his team are local experts who go above and beyond to deliver top-notch service, and they deserve every bit of your trust and business. If you need HVAC services—whether it’s a repair, installation, or just regular maintenance—do yourself a favor and call Green Mechanical LLC. Their commitment to excellence, fair pricing, and outstanding customer service make them a company you’ll want to recommend to everyone you know. Thank you, Devin, Jacob, and G, for your amazing work and dedication. You’ve earned a lifelong customer! 🌟"

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.
