The service technician arrived during the 4-hour window we had been given. He was professional and polite, asking first whether we had any issues or questions. He completely answered our one question about the air filtration system they had installed last spring. We have been using Air Treatment for years and have been consistently satisfied with their service. We'd recommend this local Vienna business to anyone in the area.
Description of Work: We have an annual contract for Air Treatment to test our heating & AC systems in the spring and fall, including replacement of filters. In addition, over the years, Air Treatment has replaced our gas furnace, A/C and gas water heater.

First, Air Treatment was efficient in providing an estimate to meet my needs: 1) replace old system, 2) allow separate control of temperatures in basement and add a air return duct to eliminate the stale air, 3) allow me to move heat from fireplace insert more efficiently through home. They talked me through the sizing of the different components and we actually decided on a smaller, more efficient A/C unit. Second, they showed up on time, did what was asked, were clean, and very responsive to my questions during the project, and finished on time. They walked me through the start-up and operation of the system. They filed for permits and sent me the followup paperwork to complete the inspections so there was no action required on my part. Third, being a meticulous do-it-yourself home renovator I was EXTREMELY impressed with the quality of the installation. All the wire connections and plumping work was very neat and routed well around the other home systems. Their duct work was very precise. Bottom line. You can trust this company. Regarding the operation of the system I could not be more pleased. Sure it cost some money for top of the line equipment, but when you look at the other big expenses in life and think about how often you get to enjoy them the ROI on this new system is immediate. With the zoning system in combination with Infinity equipment, we can heat the basement without making the bedrooms too hot. Conversely, we can air condition the bedrooms without freezing out the basement. We are looking forward to the summer months where the humidity management function will be a great benefit. Also, as part of the work we raised the return duct in the family room from the floor to the ceiling so that heat from fireplace insert can be distributed more efficiently through the house by using the very low speed function on the furnace that continually circulates and cleans the air in the house. With the fireplace insert providing heat we did not need the gas heat from the furnace for the upstairs, and when the basement needed heat the furnace only had to run at 40% capacity for short periods of time to heat the smaller space.
Description of Work: Replaced 20yr old system with new Carrier Infinity system components (Furnace, A/C, humidifier, and air cleaner). Also included a new zoning system that works with the Infinity system and installed electronically controlled duct vents to control temp in four separate zones.

The latest service they performed was a routine service call for my maintenance contract. As per usual, the technician arrived on time, was quick, thorough and efficient, and he cleaned up before leaving. This has been my experience over the last several years.
Description of Work: We have used Air Treatment Co. for many years now. In that time we have maintained a yearly maintenance contract with them. I have always been very pleased with their service and professionalism, from speaking with them on the phone to their service technicians. Air Treatment Company has replaced my central heating and air conditioning equipment, installed a central humidifier, and an advanced filter (I have allergies). They have never failed to do an excellent job. They arrive on time, work efficiently, and clean up before they leave. The routine maintenance service calls are the same. Quick, efficient and professional. I have recommended Air Treatment Company to family and friends, and will continue to do so in the future. When it comes time to replace my aging water heater, you know who I plan to call.
