"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

A home AC unit provides anywhere from one-half to five tons of cooling and requires approximately two to four pounds of refrigerant per ton of cooling. At approximately five to 10 minutes to fill one pound of refrigerant, a home that requires three tons of cooling will take about six to 12 pounds of refrigerant and approximately 30 minutes to two hours to completely recharge the unit.

To make the most out of your AC, consider implementing the following best practices: 

  • Choose the right size AC for your home to ensure your unit runs as efficiently as possible.

  • Choose a window with shade, as direct sunlight can cause your AC unit to overheat. 

  • Clean or replace the filter at least every two months. 

  • Inspect the AC’s fan and straighten it if necessary. 

  • Discontinue use immediately if you suspect a malfunction, as running the AC while broken can lead to significant issues. 

  • Turn off (or adjust the temperature) when you leave the house.

When your HVAC system is loud, a few different causes are possible. If you have loose connections or bolts in the hardware, they can rattle as the system runs and vibrates. If you have an extremely dirty furnace filter, it could cause the system to generate noise. More commonly, an excessively loud HVAC system indicates a malfunction in the system. You may have a blower motor that is close to failing or a compressor that is breaking down. These issues require an immediate inspection.

Yes, a dirty air filter can cause a higher electric bill. That’s because clogged filters make it harder for air to flow through your HVAC system, which forces it to work harder and use more energy. According to the U.S. Department of Energy, replacing dirty filters can save you between 5% and 15% in utility costs.

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.
