Gas Pack Installation and Repair
One HVAC gas package unit for heating and cooling, built for Union County’s swings between seasons.
A gas pack combines a gas furnace and an air conditioner into one HVAC gas package unit, which makes it a common choice for homes without basement space for separate equipment or for anywhere the outdoor unit needs to sit on a roof or a slab beside the house. Byrum installs and services gas pack systems throughout Marshville, Monroe, and the greater Union County area, sizing each unit to the home it’s heating and cooling.
A gas pack furnace runs on natural gas for heating and switches over to standard air conditioning for cooling, all from the same cabinet. Whether you’re replacing an aging gas pack unit or installing one for the first time, our technicians walk through what actually fits your home instead of defaulting to whatever’s easiest to install.

Inspect & Repair
Our technicians diagnose and fix a range of issues with gas pack units, from a failing furnace component to a compressor problem on the cooling side. We track down what’s actually wrong before recommending a repair, since a gas pack combines two systems in one cabinet and the fix depends on which side is causing the trouble.
Installations
A gas pack installation gets sized to your home’s heating and cooling load, not just swapped in as a same-size replacement. We handle the full setup, from removing the old unit to testing both the furnace and cooling sides before calling the job done.
Maintenance
Routine maintenance on a gas pack covers both the furnace and air conditioning components, since neglecting one side eventually affects the other. Staying on top of it keeps the whole unit running efficiently and helps you avoid the repair calls that come from a system that’s never been serviced.

FAQs
What is a gas pack, and how does it work?
A gas pack is an HVAC system that combines a gas furnace and an air conditioner into a single outdoor unit. It uses natural gas for heating during the colder months and switches to the air conditioning side for cooling once temperatures climb. Housing both in one gas package unit means one system handles year-round comfort instead of running separate heating and cooling equipment, which is part of why gas packs are common in homes without room for a furnace inside.
What are the advantages of installing a gas pack?
A gas pack keeps all your heating and cooling equipment in one outdoor unit, which frees up space inside the home and simplifies maintenance since there’s one system to service instead of two. Gas heat also tends to warm a home faster than an electric heat pump in colder weather, which matters during Union County’s occasional cold snaps.
How often should a gas pack be serviced or maintained?
Once a year is the standard, ideally in the fall before the heating side sees heavy use, though some homeowners split it into two visits, one before summer and one before winter, to check the cooling and heating components separately.
How do I choose the best gas pack HVAC system for my home?
The best gas pack for your home depends on your home’s square footage, insulation, and how the ductwork is laid out, not just the unit’s efficiency rating. A technician can calculate the actual heating and cooling load for your home and recommend a system sized to match, rather than a generic recommendation based on square footage alone.
Can a gas pack be installed on the roof, or does it need to sit on the ground?
Both are common. Gas packs are frequently installed on a roof for commercial buildings or on a concrete slab beside a home, and the right placement depends on your property’s layout and local code requirements.
What areas do you serve for gas pack installation and repair?
Byrum installs and repairs gas pack systems throughout Marshville, Monroe, and the surrounding Union County area, along with nearby areas of Mecklenburg, Anson, Cabarrus, and Stanly counties in North Carolina, and Lancaster and Chesterfield counties in South Carolina.

Great company with very professional sales and service staff. Would highly recommend Byrum to anyone. The new unit installation has cut my energy bills in half compared to what they were for the same period last year. My only regret is not having have done it sooner. Even the city inspector commented on the excellent quality of the work completed.

It was very hot outside, our A/C went out. Another company left us for 4 weeks and still could not say when the new A/C would be installed. Byrum responded immediately, brought a portable A/C unit and installed it until they could get the new one. Within a week, it was installed. Every single person was kind, caring, professional. Everything was explained in detail, the work was excellent, prompt and neat. Could not have dreamed of a better company to take care of my needs. THANK YOU!
