"I was impressed with the quality of the work performed by ð ¼-1 ð ¿ð ªð ð © ð ¾ð ¡ð ð ð £ð ð £ð ð ð ð §ð «ð ð ð ð ¨ in both cleaning the HVAC and dryer ducts. As a former Army Contracting Officer's Representative, what impressed me most was the work ethic displayed by Kieth. He worked until the job was done, even staying until after 1:00 AM to make sure the work was finished correctly. I would not hesitate to hire him again."

"I had a great experience with Vortex Air. They came to my home and professionally installed a Bosch unit. The entire process was smooth, timely, and handled with a high level of professionalism. They showed up on time, completed the work efficiently, and were very cost-effective compared to other options I looked into. I highly recommend Vortex Air for anyone looking for reliable and professional HVAC services."

"Under new Ownership! I have known the owners personally for 20+ years and can attest that they are amazingly generous, kind, and selfless people. Last month, the HVAC went out in one of my rental homes. I was out of town, and Excel flawlessly completed the project on time and without any complications. My tenants were completely satisfied with the level of professionalism they demonstrated, and I found their pricing to be very reasonable. I'm switching my HVAC company to Excel because of my inside knowledge of who the owners are and the high level of reliability and integrity the possess. You can't go wrong with Excel!"

"David is very responsive and professional. He did some complicated rerouting of the lines into our house and managed to fit an air handler into a space when another well known area HVAC company said it couldn't be done. When the brand new unit wasn't working properly this winter he immediately serviced it. He is definitely our go - to person for anything HVAC related. Thanks David.

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.

It’s critical to use the right size AC for your space and not go too small or too big. If you purchase an undersized unit, it won’t properly cool your house, and it has to work harder to reach the optimal temperature. This will eventually wear your unit out. An oversized unit can spell trouble because it will turn off and on more frequently, which also wears out your AC unit. An oversized unit also causes humidity in the home.

For washable or electrostatic air conditioner filters, you can soak and rinse them with water. If you rinse the filter with water, make sure to use a faucet, shower head, or garden hose with a gentle water pressure setting, as strong water pressure could damage the filter.

But for disposable filters, water could ruin the filter, even allowing mold to grow in the filter. Instead, these filters should be replaced.

To keep a window air conditioner in good working order, you should clean the filter regularly, inspect the seals, and store the unit properly during the off-season.

A calculation method that your HVAC contractor will use to ensure your system does what it's supposed to is measuring duct output, or its CFM. The calculation requires knowing the cross-sectional area of the ductwork and determining the air speed past any given point within it.
