If you’re having trouble with your heating or air conditioning system, then D.A. Gsell is just a phone call away. We care about our customers and their comfort and we take great pride in servicing your system and keeping everything clean.

Our technicians are professionally trained and very experienced in all major brands of HVAC Systems.

Sales & Installation

We promote state-of-the-art comfort control and are at the forefront in providing our customers with reliable, affordable and highly efficient heating and air conditioning products.

Our extensive residential and commercial HVAC experience in the Chambersburg-area gives us insight to this climate and informs our recommendations for heating and air conditioning solutions that are right for your needs. We believe in our products so much that we do not install anything for our customers that we do not use ourselves.

We proudly carry the complete line of York® heating, air conditioning and indoor air quality products. When you purchase and York product you are investing in cutting edge technology and high efficiency like the York QuietDrive System, which makes the unit almost completely silent. And for those who care about the look and style of outdoor units, we offer custom color panel options. Custom color panels are available with York Affinity air conditioners and heat pumps -- they are an instant hit.

Residential Services

We offer a full range of services to residential customers.

Our technicians are trained on all major brands of HVAC equipment and can solve any problem you’re having.

If you’re looking to upgrade to a new, more efficient system we can help you there as well. We can show you the latest equipment from York that’s very energy efficient and also very quiet. There are many new options with the new equipment; you can even select the color of the panels on the outside units.

After we answer all of your questions, we can place the order and when it arrives, we’ll do the complete install of the new equipment in your home.

Commercial Services

We also service commercial cooling and heating systems. We understand how important heating and cooling is to your business and we are there to get you through any problems that you have.

If it’s time to upgrade or install a new heating or cooling system for your business we’ll come out and discuss the available options and provide you complete end-to-end service from the sale of the unit, through installation, and we’ll be there after the sale. Our goal is to impress you with our service-after-the-sale professionalism.

Indoor Air Quality

A study conducted by the U.S. Environmental Protection Agency found that indoor air could actually be more polluted than outdoor air.

Considering that most individuals spend up to 90 percent of each day indoors--more than half of that time at home--you may be experiencing indoor air pollution without even knowing it.

Today, homes are sealed more tightly to conserve energy. Unfortunately, this seals in mold, pollen, bacteria and other pollutants. And since the U.S. EPA ranks indoor air pollution among the top five environmental risks to public health, many homeowners are concerned.

Fortunately, there's a solution to most indoor air quality problems. York offers an array of choices designed to ventilate stale indoor air, zap airborne germs, trap airborne particles and moisturize parched air.

The York® UVC Germicidal Light was recently selected by a panel of industry professionals to be awarded as an Honorable Mention in the Indoor Air Quality category of the 2009 AHR Expo Innovation Awards Competition.

With York® products, you can be confident you are selecting high quality, pioneering equipment and components.
