Why Work With Us?

There is one key thing that sets us apart from the competition: Value added services. At ACIA we offer more value added services than any of our competitors at no additional charge!

ACIA = Certified Indoor Air Quality Professionals

With over twenty years of experience in the industry, our experts can visit your site and make recommendations on how to be more effective in filtering your building’s air, which may include helping to reduce the number of filters being used in a building, reduce energy consumption and provide “green” solutions.

ACIA = Just In Time Delivery

ACIA operates out of a large warehouse located in central Pennsylvania allowing us to keep in stock thousands of filters. How does this benefit you? ACIA puts you, our customers, on a delivery schedule and will warehouse your orders at no additional fee, saving in the expense of pricey storage space and simplifying the ordering process because now there is no need to call, we know what you need and will deliver it before you need it.

ACIA = Low Cost Products

Although we offer name brand products, ACIA also offers low cost alternatives potentially saving you thousands of dollars every year. Plus, we purchase products in bulk and pass these savings to you.

ACIA = Specific Tagging & Broken Case Quantities

We realize that most of our customers are buying products for an entire building, not just one unit, which is why we offer broken case quantities. Most of our competitors don’t want to waste the time doing this but at ACIA, we sell you only what you need. We will package your order in a way that makes it fast and efficient for your employees to do their jobs and combine each unit’s filters and belts together in one package so that a service technician will have everything they need all in one box if needed.


Provide cost effective solutions for improving air quality

At ACIA we offer both brand name products as well as high-quality replacements at cost-efficient prices, educating our customers on a more cost effective way in which to filter their building’s air. We know that in today’s economy budgets are tight so we do our best to provide your company with the most efficient and effective means of filtration.

Provide exceptional customer service

It is our job to create an excellent experience for every customer. We know how frustrating it can be when faced with poor service, which is why we take every necessary step to make sure you are satisfied with your purchase.

Create “customers for life”

The idea of creating a customer for life was something that our business was founded upon. While many of our competitors are aimed at making high markups and big profits, at ACIA it’s personal. We would rather charge a fair price and develop a close friendly rapport with you resulting in a long business relationship.

Provide Certified Indoor Air Quality Professionals (CIAQP’s) for our customers

With today’s air quality regulations continually changing; it is ACIA’s job to be on top of those changes and keep you aware of what you may need. Our CIAQP’s monitor new DEP, OSHA, Department of Health, CDC, NIOSH guidelines and clean room standards and educate and train you on how these changes may impact you.

Be A One-Stop-Shop

Whether you are looking for air filters, fan belts or coil cleaners, at ACIA we have it all! With hundreds of HVAC products from which to choose, we can meet every customer’s needs. If we don’t carry a particular product you are looking for, we can in most cases find it for you or better yet provide a more cost effective alternative.


From air testing and duct cleaning, to filter change-outs and many more.
