"Worst service I’ve ever have experienced. They wanted to sell me the product, never told me that there was an early termination fee and another penalty for an initial offer they gave me. Had double charges every month, once for the oil they provided (which they never told me they were going to provide before coming. They just came without my knowledge and then I find a high amount bill) and another for an “automatic payment” for 500 that they never could explain. The didn’t even fix this issue and it kept happening every month even after I cancelled the service. Then having to call them is a hastié for the refund of the 500. Stay away of this company"

"I had an AC installed in July 2023. There is a coolant leak due to a valve that the installer admitted he had issues installing. I reached out the first week in May and the installer said it would be two weeks to get the part installed under warranty. He was apologetic and admitted fault. The company then strung me along for two months repeatedly telling me they would be out soon. Then they stopped answering and have ignored any calls and messages. It has been almost 3 months since I contacted them originally about the issue and they seem to not honor warranty coverage. "

We are the #1 Geothermal Heating and Cooling Experts in South Jersey, Central Jersey, and Southeastern Pennsylvania.  The U.S. EPA calls geothermal "the most energy efficient, environmentally clean and cost-effective space conditioning system available".  Upgrade to geothermal, and never buy heating oil or natural gas again. Don't just take our word for it when it comes to D&L's geothermal expertise. Here's what one of our recent customers had to say: “D&L has been an absolute life saver. We had the hardest time finding a tech who knew anything about geothermal systems, until we called D&L... A real standup, old school, quality service company. D&L got a new long-term customer in me, and I strongly recommend them.”

"He has done a good job."

"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.

"Jeff and his team did and excellent job with the installation of two Daikin HVAC units. I had many questions about the units and install and they were quick and thorough in responding. The price and warranty were competitive with high end brands. The crew was courteous and professional during the two day install. They were the only company that included replacement of the coolant lines, rather than just flushing the old ones. So far the Daikin variable speed AC units are exceptionally quiet and the house is very comfortable. Would recommend Ace Home Services and Unique Comfort without reservation."

Heating and Air Conditioning questions, answered by experts

The size window AC you need depends on the BTU and the size of the room you’re cooling. For a room with 8-foot ceilings, look for about 20 BTU per square foot of the room. For example, a 12-by-12-foot room should have an air conditioner with 2,880 BTU. You can buy something slightly more powerful, but don’t overshoot the BTU for a small room, or you’ll waste energy and have higher bills.

As mentioned above, not all HVAC Schrader valves are necessarily the same. While the valve core and pin or spring size on Schrader valves used for HVAC are generally similar, the valves are not all universal and interchangeable. The size of Schrader valves varies depending on whether it's used in an air conditioner, bicycle tire, or motor vehicle tire.

This depends on the extent of the freezing. Some ACs only need an hour or two to thaw out, but others may need a full day to completely unfreeze. Once you turn off the system to let it unfreeze, check it periodically to make sure the drain pan doesn’t overflow. When you turn the system back on, keep an eye on it to ensure it doesn’t start freezing again.

The standard rule for return duct sizing is that the return vent should be the same size or larger than the supply vent. This will ensure balanced airflow in your home and reduce strain on your HVAC system.

Some HVAC systems tend to use R410A refrigerant, although if you have an older model it may be using R22. R22 is banned due to its harmful environmental and health impacts, and it is a sign that your AC unit is old enough to consider a replacement and the significant efficiency gains that could come with it.
