"They were the HVAC sub on our total house remodeling due to a house fire. We decided to add central air because the walls and ceilings were open and we at the time had window units. They installed a heat pump with a Nest thermostat. In addition to the heat pump the house had an existing radiator heating system. However, the hot water heater, boiler, and water line were damaged or clogged due to the fire. T & J replaced everything and were extremely polite and explained everything as well as how to do simple repairs. I would recommend them to my friends and will definitely be using them for annual maintenance."

"ALAN IT FIXED THE PROBLEM!! The reason why I did not hire this company was because Alan gave me a few troubleshooting tips about my AC. I thought I had a bad compressor, which was going to cost me over 8k to replace due to being a old system that no longer is being manufactured, but after telling Alan that I had some general knowledge about AC from my military service, he shared with me a few things to check and IT FIXED it. I went from potentially spending 8K to only spending 13.00. When ever my AC really does break, this company has earned my business for being honest and transparent and not trying to rip off their customer. Alan you the man!"

Air Conditioning questions, answered by experts

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.

If your whole house is cold that’s one thing, but what if you only have a few rooms that are cold? First, you need to determine why this may be happening. A good place to start is to investigate the potential causes listed in this article—heat transfer, airflow, thermostat problems, humidity, and insulation. Once you’ve narrowed down the issue, you’d apply the same principles to the cold rooms as you would to the entire home.

If you don't clean your AC evaporator coils, dirt and debris will build up, which impairs the system's ability to transfer heat. This forces the unit to work harder, leading to inefficient performance, higher energy bills, and frequent breakdowns. Over time, neglected coils can corrode, which may cause refrigerant leaks, or develop mold, ice buildup, and a clogged condensate drain, resulting in poor air quality and an uncomfortable home.

If you’re looking for a portable, budget-friendly cooling solution that doesn’t require any venting or installation, a ventless AC system is a good option. Similarly, this is a great choice if you’re renting an apartment or home and aren’t allowed to make large, structural changes like installing comprehensive HVAC, or you’re in a shared space and only need to cool your own room.
