Andrew Knezevich A/C & Heating runs its operations from Pflugerville, Texas, and specializes in HVAC services for residential properties. The crew deals with air conditioning units, heating systems, and ventilation components on a regular basis. Customers in the area call them when their cooling breaks down or when ducts need attention due to buildup and other issues common in the local climate. Andrew often leads the inspections and makes sure everything gets explained clearly from the start. Homeowners reach out for both quick fixes and more involved work on systems that have sat unused or collected debris over time.

They handle full checks on air conditioning setups and air ducts where mold shows up inside the equipment. One job involved a deep cleaning after the inspection turned up growth, with before and after pictures taken to show the results. Andrew arrives on time for dryer vent cleanings and system reviews, walking through the ducts, plenums, and vents while explaining each step. The team finishes by clearing the workspace and confirming the dryer vent and other areas run clear without leftover mess. These visits cover everything from initial looks at the whole setup to completing the cleaning work on the same day when possible.

Customers keep coming back because the work holds up without shortcuts, calls get answered fast, and prices stay straightforward with no surprises added later. Communication stays direct from the first contact through the final check, and jobs move along without delays even on short notice.

“Andrew from Andrew and Sons Air Duct Cleaning arrived on time and started with an inspection of the system. He took the time to explain what he was seeing and discuss the work before beginning. The ducts, plenums, and dryer vent were cleaned, and he explained the process along the way. Everything was sealed properly afterward, and the work appeared very thorough. Overall a professional experience. I appreciated the time he took to walk me through everything and the advice he shared along the way. The whole experience felt personal rather than just another service call. I will continue to use Andrew and Sons and would recommend them to anyone needing these services.”

He was always responsive, clear, and helpful when setting everything up, including explaining my options and finding a flexible time to accommodate my busy schedule. Much better in comparison to the treatment and other quotes I had received up until then. The technicians did an excellent job. They were courteous and professional.
