"Helpful meets Helpful-Unique Indoor Comfort is now Ace Hardware Home Services, a fourth-generation heating, cooling, plumbing and electrical service company based in King of Prussia, PA. We are a customer service company that happens to excel in heating, air conditioning, plumbing and electrical home services. We have a unique reputation for superior service and quality craftsmanship --- but don't take our word for it --- Experience the Unique service firsthand." Providing HVAC service and repair, system replacement, and air conditioning solutions for older homes. Residential plumbing service, repair, emergency service, and water heaters. Electrical emergency service, repair, home upgrades, generators and EV Chargers.
"We could not be happier with choosing Unique Indoor Comfort for our new HVAC system. We found this company by being referred by a client of my husbands. The original duct work in our house was extremely undersized, over working our unit and not creating good airflow to reach the third floor of our town home. Reni came out to our home, and took the time to explain to me options with Unique to really make our new HVAC unit/system efficient and comfortable temperatures in our house. I really appreciated his kindness and patience with me with all my questions. Unique was able to get us scheduled within a week or finalizing the contract, just in time in end of April when the first heat wave hit. It has been almost two months now since Henry and Matt installed our new HVAC system (they both were friendly and did an excellent job) and we are truly enjoying it. With a new baby in the house, it is a relief to have this new unit and ability to cool down our house quickly and efficiently. I know it is a lot interviewing and getting quotes from different HVAC companies - it is a big investment. This company truly stood out for us and were able to work with our budget and our needs for our home. They were the only company who proposed how we could add an additional vent to allow more airflow, and to redo the duct work to the proper sizing for our house and up to code. We are very grateful and HIGHLY recommend Unique. Thank you Reni, Matt and Henry again!"

"I scheduled an appointment with them in response to their ad to flush a hot water tank for $49, no trip charge or add on expenses. After scheduling and in advance of the appointment I called for details regarding the service to be provided at this very hard to believe price. No matter what time of day I called I was always routed to an answering service that only scheduled appointments. Each time they said they would reach out to a manager to get my questions answered. After 3 calls and an email without a response, I cancelled my appointment."

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.
