"They cleaned the outside AC unit, checked the charge in the system, and replumed the PVC drain for the AC coil unit attached to the furnace quickly, completely, and for only $140! I already have additional work going their way, just waiting for it to get scheduled. Very satisfied."

"He came out within about 2 hrs of me calling, which was great. He cleaned everything, replace freon, and advised me on how to handle future problems. The best thing was he did not try to sell me a new unit. All of my HVAC equipment in my house is older, and anytime I have had anyone else over for any reason they always try and sell me on new furnace/AC etc. He did not. He was quick and professional and it was appreciated. I will definitely use and recommend him in the future.

"Computer did the "gotta send info to Microsoft" but when tried to reboot it ran through automatic repair without success. I did all the alternative without any success. He came and picked up the hard drive on Tuesday and returned it on Saturday. Fortunately he was able to "restore" without any data loss. Very happy with outcome."

Air Conditioning questions, answered by experts

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.

Ideally, an AC system should never need more Freon (a popular refrigerant) because it circulates in a closed loop. However, refrigerant leaks are not uncommon and may occur gradually over 5 to 15 years. If your system has a leak, it will need to be topped up in a process known as an AC recharge. Signs of a refrigerant leak include weakened AC performance, increased humidity in your home, higher utility bills, and a hissing sound from the unit. The cost of an AC recharge will depend on the size and type of your AC unit, as well as the type of refrigerant it uses.

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.

There are several steps you can take to prevent your AC drain from clogging. This includes cleaning the drain line at least every three months, changing the filter every one to three months, and getting your AC serviced annually. Also, if any problems arise with your AC, hire an HVAC technician to deal with them ASAP.

Some of the signs of HVAC issues include rising energy bills, rooms not cooling or heating properly, loud noises when in operation, and signs of condensation. To illustrate, if you’re wondering how to stop condensation on air vents, you’ll need to have your HVAC inspected.
