"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!"

"Dillon diagnosed our problems in minutes and after calculating what we needed exactly and us giving the go ahead he sin the job right then and there after getting the parts needed. He actually fixed our ongoing problem that discount mechanical couldn't diagnose after hours and taught us about what needed to be done down the the tiniest detail and how to keep it on the up and up. I'll never call another plumbing & heating company again, these guys are actually honest and they do the job when they say they're going to do it. It's amazing to meet honest people nowadays."

"They have contacted me for a quote but I have not yet heard back from them. I am leaning toward contacting a friend to assist me in building it myself as I am concerned that I will not be getting the custom project that I need. If they surprize me and are able to come back with a quote for the project we need, I will most likely hire them for the job."

Heating and Air Conditioning questions, answered by experts

The cost to add Freon to an AC ranges from $100 to $350. It can increase up to $600 for large AC units requiring much more coolant. The cost also depends on how much refrigerant your unit needs. If only a small amount of Freon leaked out, your cost would be on the lower side. A complete replacement of all the required refrigerant can get expensive.

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.

When deciding whether to repair or replace your air conditioner, several factors should be considered. It is generally worth repairing the unit if it's less than 10 years old, the warranty is still active, and you're dealing with a one-off issue. Most central AC units last about 15 years, while window units last 8 to 10 years. If your unit is approaching or has surpassed the 10-year mark and requires frequent or costly repairs (e.g., over $5,000), replacement is often the more sensible long-term investment. For older, inefficient, or out-of-warranty units experiencing multiple problems, replacing it is typically the better choice.

Air filters with a high MERV rating, 11 or above, shouldn't cause airflow problems in most residential systems. However, the airflow can be restricted in some HVAC systems if they aren't designed for high MERV ratings. If in doubt, a local duct installer should inspect your ductwork so that you know what your system can handle.

High humidity is one of the most common reasons for air vents to sweat or produce condensation. When the cool, dry air from your HVAC unit meets warm and moist air in your home, it will cause condensation. Insulating your ductwork can help prevent this. If you live in a very humid region, a dehumidifier can also help.
