"Duke did a great job at a fair price. We needed AC and decided to replace our old furnace at the same time. In addition Duke wrapped with insulating bubble wrap our old ducts that were exposed. He tied the drip line into our existing downspout in a neat fashion. I'd highly recommend him (he's a fellow submarine vet too!!)."

"The TASK service professional was prompt, friendly and explained very thoroughly what he was going to do. He was very thorough and kept me apprised of the vent and HVAC conditions he noted. After the vent system cleaning was done I noticed a big improvement in air quality > I could breath easier and deeper, the air in my home was fresh and I've also noticed that my home heats up faster and stays warmer at lower thermostat settings. I highly recommend TASK."

"Albert Nahman PHC installed new AC and Furnace for my house. I like them for several reasons -- 1. At first Tom explained in detail what equipment I need and how they work, and gave me a reasonable and detailed quote at end of the visit. 2. They offer interest free finance. 3. I got free upgrade for furnace when the original quoted is not available. 4. Their installer did good job, and cleaned up afterward. I highly recommend this company."

Air Conditioning questions, answered by experts

Yes, it's normal for air conditioners to leak tiny amounts of water due to condensation. Under normal circumstances, all excess moisture travels to the drain pan to be pumped through your system's drain line. You should call a technician to diagnose the issue if you're noticing frequent leaking or pooling. It's also important to investigate if your homeowners insurance can cover water damage.

Yes. Return air vents are responsible for gathering and pulling in the warmer air. Once they draw it in, your system conditions the air by removing the warmer molecules from it, allowing your air conditioner to dispense the cooler air back into your home. Not only does this create a more comfortable environment for you, but it also keeps your air conditioner from overworking, resulting in lower energy bills. 

One of the fastest ways to unfreeze an AC unit is to turn off the unit and, if it’s warm outside, use the fan-only mode to help blow warmer air through the unit to speed up the defrosting process. While it may be tempting to use a hair dryer to defrost the air conditioner, that high heat can damage the coils.

After defrosting, if you can safely solve the issue with a fix like changing the filter, go ahead and do so. Otherwise, call in a pro before turning your AC back on.

Yes, ventless portable air conditioners exist, and not all standard portable air conditioners must be vented through a window.

Ventless portable units, often called evaporative coolers, do not have exhaust hoses. They use a water reservoir and a cooling pad to add moisture to the air, making it feel cooler. These units work best in dry climates because humid areas cannot absorb much additional moisture.

For standard portable air conditioners that do require venting, a window is not the only option; they can also be vented through a door, wall, or ceiling. However, it is essential to vent these units properly. Running a standard portable AC without venting it is counterproductive because it needs to expel heat to cool the room. Failing to do so will only increase the room's temperature.

You will only need to refill your AC with refrigerant if it has a leak. Otherwise, a modern, well-maintained AC will most likely never need a recharge. You may notice a leak in an older system if your bills are higher, you hear a hissing sound, or if the air is blowing out hot.
