What Is a Packaged HVAC Unit?

A packaged HVAC unit is an all-in-one heating and cooling system that combines multiple components into a single housing unit. These systems are typically installed outdoors on the roof or a concrete pad, making them ideal for floorplans with limited indoor space. People choose them for their space-saving design, energy efficiency, and ease of maintenance.

Packaged Unit Installation & Replacement

Installing a packaged HVAC unit is a relatively quick process, usually taking just one to two days, depending on the complexity and accessibility of the installation site. These units are built to last, with a typical lifespan of 15 to 20 years when they are regularly maintained. Working with a qualified HVAC technician guarantees a smooth installation process and optimal performance of your system. With decades of experience in the Blue Ash area, we understand the unique needs of both aging and newer homes, providing tailored solutions to meet your specific requirements.

What Our Clients Are Saying

Brandon of National Heating did an excellent job servicing my AC. He is very thorough, knowledgeable, and professional. He discovered that the low outside temperature sensor had not been set up on my Evolution Connex Control and took care of it. I appreciated his top-notch service!

Thomas S.

Great company that I trust. Very thorough. I just had my air conditioner annual service. I used Help in the past. They always tried to upsell every opportunity they had. National Heating and A/C is the real deal from booking the appointment to the actual work. Every person I have dealt with is kind, knowledgeable, and…

Paul M.

I can highly recommend National (previously Nelson Comfort) Heating and Air especially if Sanjay is the company representative. He was beyond good in that he completely cleaned the outside unit and was very thorough with the ac equipment inside the house. He even destroyed a wasp nest that I had not noticed. Five stars for this…

Susan S.

Excellent experience all around. Communication from the company was timely and complete. My service technician Chad Wilson was very knowledgeable, efficient and helpful. I had a lot of questions, having just moved into a house with systems that were unfamiliar to me (geothermal, radiant heat). Chad answered all my questions and spent extra time helping me…

Mary C.

My family has been using this company for years. They've always provided us with honest feedback on pricing for repairs and maintenance. This means a lot to a family on a tight budget. We never feel like we are charged for unnecessary items. All charges are explained and examined in great detail before being followed through.…
