Heating and cooling in Burlington
Burlington grew up around the railroad shops: Alamance County's history records the maintenance roundhouse opening at Company Shops in 1859, and the town took the name Burlington after the repair facilities moved away and its people went to work in the mills. Today's houses run from mill-era homes near downtown to newer neighborhoods along the interstate, and most of them need a system that handles both a humid summer and a real Piedmont winter.
Two seasons that both matter
The nearest NOAA engineering weather station is at Greensboro/Piedmont Triad, about 28 miles west. Its data gives a 1% summer design temperature of 90°F, with a mean coincident wet-bulb temperature of 74°F, and a 99% winter design temperature of 19°F. In other words, a system here has to cool on sticky summer afternoons and heat through cold winter nights, and both loads should be part of the sizing.
The same station counts about 573 hours a year with the wet-bulb temperature above 73°F and about 2,057 hours above 67°F. That's enough humid weather that moisture removal deserves a place in the conversation, not just temperature.
Heat pump, furnace or both
Many Burlington homes use a heat pump, a gas furnace with central air, or a dual-fuel system that pairs a heat pump with a furnace for the coldest nights. Ask each contractor:
- how the system they propose performs at the winter design temperature;
- whether a heat pump will need backup heat, and what kind;
- what the expected operating cost is for each option, not just the installed price;
- how the system will handle humidity in summer, including fan speeds and run times.
Efficiency rules
North Carolina is in the Department of Energy's hot-humid Southeast region. Split-system central air conditioners installed on or after January 1, 2023 must be rated at least 14.3 SEER2 (13.8 SEER2 for 45,000 Btu/h and larger), and split-system heat pumps must meet 14.3 SEER2 and 7.5 HSPF2 nationwide. Those are minimums. Ask what a higher-rated unit would save in your house before paying more for it.
Sizing and ducts
A replacement should start with a load calculation for your house, not the size of the old unit. Ask the contractor to look at the ducts too: leaky or undersized ducts in a crawlspace or attic waste energy and leave some rooms hot or cold no matter how good the equipment is. Older homes near downtown may have ducts that were added long after the house was built.
The license threshold
The North Carolina Licensing Board for General Contractors says that by law a general contractor must hold a state license when the total cost of a project is $40,000 or more, and its website has a public license search. Whatever the size of the job, ask the contractor which state license covers the work, and look it up before you sign.
Comparing quotes
Put the quotes side by side on the same terms: equipment brand and model numbers, SEER2 and HSPF2 ratings, the load calculation, duct work, thermostat, removal of the old equipment, the permit, the start-up and commissioning checks, and the parts and labor warranties. A quote that only lists a tonnage and a price doesn't give you enough to compare.
