Air Ducts

Faulty ductwork can create a lot of issues in your Columbia, MD, household. Leaks and tears create an escape route for the conditioned air while allowing dust, debris, odors, and other contaminants to infiltrate your home. Your heating, ventilation, and air conditioning (HVAC) equipment has to work that much harder to compensate for the escaping airflow—and you pay the price in reduced indoor air quality (IAQ) and higher utility bills.

Environmental Systems Associates has a solution—our air quality specialists can inspect your air ducts for leaks and loose joints. We take pressurized readings to pinpoint tears and leaks. Plus, we can peek inside the ducts to determine if they need cleaning.

Ductless Systems

A ductless system, or mini split, connects an outdoor condenser unit with an indoor air handler to warm or cool any part of your Columbia, MD, home. These systems work great if you’re adding a new addition to your home because you won’t need to extend your ductwork.

Give Environmental Systems Associates a call to learn more about ductless systems. Air ducts tend to stir up dust and other allergens—ductless systems do not. A ductless mini split offers relief for members in your home with allergies or asthma and can help improve your home’s indoor air quality (IAQ).

“I had a great experience with ESA. Every one I spoke with on the phone was very helpful as well as the technicians who came out to do the job. I am very happy and plan on using this company again in the future.” – Emelie B.

“Noticed that on my thermostat I could not set the system at AUTO. Also had questions about adding a dehumidifier. Contacted ESA on 6/27 late morning. Was transferred to Scott for technical information. He asked lots of questions and told me he wanted to research the specifics of my system and would call back, probably that afternoon. Scott called first thing in the morning of 6/28. He apologized for not getting back to me sooner. He walked me through the steps necessary to correct the issues with me at the thermostat and Scott instructing what to do. It took about 15 minutes, and everything was done and I learned more about the system. He asked if I was happy with the results, which I was. We agreed to see how the changes impacted the system moving forward. The process addressed my concerns without the company sending someone on a service call. Win-win! My next service will be for my fall maintenance as I have a service contract. Have been a customer for at least 20 years and highly recommend the company.” – Carole K.

“ESA, thank you for providing end-to-end quality customer service. You are to be commended for your consistency in providing such skilled technicians as the face of your company. Specifically, I would like to recognize Alex, Ryan L., Seth, and John. I had the opportunity to work with them as a team on the installation of my recently installed Carrier system. Alex was instrumental in providing the very expert guidance as I pondered the needed replacement. Ryan professionally led his team on the smooth installation. I continue to be pleased with the quality service made possible by those mentioned. I look forward to working with Alex, Ryan, and the team, as my assigned technicians. They are AWESOME!” – Shirley M.

“Brian Warren did a great job figuring out that my Y1 had issues. We had an extra wire in the line so he used that one replacing the yellow wire. Double checked the heat exchanger to be sure it was getting a signal. Very thorough and polite.” – Christopher B.

“I have been using ESA as my HVAC maintenance company since relocating to MD over two years ago. I have always been impressed with their professional service and knowledgeable staff. ESA notified me of severe rusting problems with my townhouse’s 22-year-old gas furnace following annual inspection. With their help and advice, I chose a new Carrier furnace as a replacement. It was installed in mid-January by a very capable crew. Cody, Dylan and John M did the work on time, cleaned up afterwards and explained the new furnace’s features and operation. I am completely happy with the result and glad to recommend ESA to all concerned.” – William P.

“Wow! I see why they’re the best in Howard County. Richard ensured we received the best quality service. He was fully transparent about what was and was not needed. Alex did an outstanding job at figuring out what was wrong with the unit. Moreover, they did not leave until it was fixed. Honest, knowledgeable and reliable. I highly recommend their services! Thanks again!” – Viridiana M.

“The weather had shifted and we were freezing. Our heat was not working. With limited availability due to work, I was hoping to be seen asap. They had a cancellation, and fit me right into their schedule. The service technician was friendly, professional and fixed the problem in minutes. I appreciate their honesty and excellent service. I will forever be a customer and highly recommend ESA.” – Diana Cantrelle M.
