"My combo boiler/hot water went out yesterday Moore did a great job and came up with innovative solutions to get it fixed quickly - very pleased as temps are going to below zero and big snow has begun. Also great job on mask-wearing for COVID. I have used Moore Heating, including buying my boiler from them 9 years ago, and very pleased with their professional service!"

Heating and Air Conditioning questions, answered by experts

They can, but it’s not as common. Window AC units are much smaller than whole-house systems and less likely to develop refrigerant leaks or similar issues. As a result, you will rarely need to add a new refrigerant, limiting overcharging problems. However, it’s still important to leave refrigerant management in the hands of professionals when window units need work.

High humidity, bad insulation, warmth from sunlight, and poor circulation are all reasons your home’s hotter inside than out. While this is what you want in the colder months, summer can become unbearable if this is a constant. Try to find the cause, but you need to remember that issues like this require a permanent fix (unless you want to bear down during the summer months).

If you know how to identify supply and return ducts, you’ll find that only the supply ducts will have dampers. Although your return ducts can have dampers, it’s not common. If you have one return duct that is pulling in too much air, adding a damper to it can help with overall system performance. However, dampers on return ducts are not a necessary addition for most homes.

It is normal for the attic to be hotter than the rest of the house in the summer, but only by about 10 or 20 degrees. Attics that aren’t properly insulated or ventilated can reach temperatures of 130 degrees or more which can cause damage to the home’s structure, including the roof, wood framing, and HVAC system.

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.
