What Caused My Rental to Have No Heat in Durham?

Durham · November 2026 · Autumn · From our service records

What the customer reported

A tenant in a Durham home in the 27701 area reported that the system was not producing heat.

What we found and did

Autumn found the system was shorting and repeatedly blowing the low-voltage fuse, and further troubleshooting pointed to a faulty thermostat. She bypassed the thermostat to test system operation, but the indoor control board failed during testing. The system now needs the thermostat and the indoor control board replaced before more diagnostics can show whether any other issues are present. Autumn gave the customer two repair quotes: one using customer or property-supplied parts and one using parts supplied by the company.

Why Did a Home Inspection Flag My Furnace in Durham?

Why Did a Home Inspection Flag My Furnace in Durham?

What the customer reported

A Durham home buyer in the 27703 area asked for a furnace check after furnace concerns were noted during the home inspection, including a corroded furnace that may have been caused by condensation. The buyer wanted a diagnosis in writing.

What we found and did

Mario found that the 9-year-old attic gas furnace is in overall good condition, but its blower capacitor is out of range and needs to be replaced. He started inside the home by verifying thermostat operations and checking filter conditions. In the attic he visually inspected the ductwork, refrigeration lines, drain lines, electrical wire connections, zoning components, and blower wheel cleanliness, and he checked line/control voltage, blower motor amperage, inducer motor amperage, and blower capacitor values. He also recommended a few standard maintenance cleanings and a blower wheel cleaning, and noted that typical life expectancy for this equipment is around 12 years, which is worth keeping in mind for future planning.

Heat Only Works When Fan Is On in a Durham 27707 Apartment

Heat Only Works When Fan Is On in a Durham 27707 Apartment

What the customer reported

A Durham apartment resident reported that the heat only works when the fan is set to on, and the dispatcher noted it might be a thermostat problem.

What we found and did

Jeorell found the thermostat dip switch set to HG instead of HE. On arrival, the blower would not run but the heat strips came on, and setting the blower to on made the system start to heat. Jeorell verified all 24v wiring to make sure there were no breaks and that the system was getting proper voltage, then switched the dip switch to HE.

Result

After the switch to HE, the system started to heat properly and was heating at the time of departure.

Durham · October 2026 · Chris & Mario · From our service records

What Caused No Heat in Two Durham Apartment Units?

What the customer reported

A property contact in the 27707 area reported no heat in a unit with a recently installed system, and a second unit that was not heating. The homeowner wanted the work done today or tomorrow.

What we found and did

In the first unit, Mario found the thermostat wiring was wired incorrectly for W on the recently installed system. He corrected the thermostat wire connections and fully tested system operations. In the second unit, he confirmed thermostat operations and performed voltage diagnostics, which showed the heat strip breakers were switched to the off position at the unit. Mario switched the heat strips back on and tested system performance.

Result

Both units were operating properly with no further issues observed.

Apartment Heat Running but Not Blowing Hot Air in Durham

Durham · February 2026 · Jeorell · From our service records

What the customer reported

A Durham apartment in the 27701 area had a unit not heating. The system would come on, but it was not putting out hot air.

What we found and did

Jeorell made a call for heat at the thermostat, and the system came on, but it was not hot air and the line set felt cold. He jumped out R and Y at the thermostat, and the system started to heat, pointing to the thermostat as the problem. After reviewing the findings with the service manager and getting permission, Jeorell replaced the thermostat and programmed it, and the system started to heat right away.

Result

Jeorell measured 90° from the supply vents, and the system was heating at the time of departure.

Reviews

What Durham customers say about our heating work

It is now January of 2026, Service Technician Aaron has just completed the inspection and maintenance of my HVAC system. I continue to endorse the proficiency and professionalism of this company and their technicians. My equipment continues to work beautifully. I continue to endorse all of the applicable comments below. This is a company I can recommend without reservation. ——- Element Service Group has been a very professional company to work with. Aaron arrived on time he identified himself upon arrival, was wearing a shirt with Element Service Group name and as usual was driving a well branded truck in excellent repair. Aaron performed my spring inspection and maintenance and provided a detailed assessment of suggested upgrades I could share with my son. Once all work was completed he gave me an update on my system and work performed. All conversations were articulate and polite. My receipt was emailed to me in a timely fashion. Once again I can highly recommend Element Service Group. One side note when this company first began working on my system it came with a lot of noise on start up. Due to these technicians proficiency my system now “purrs”. I am barely aware it is functioning. I am so grateful it maintains a comfortable environment in my home along with my nest thermostat that they helped me install. Once again, if you are looking for a reliable and professional company call Element Service Group. Disclaimer: I have no affiliation with the company, owners or employees. I am just a satisfied customer.

Why quality heating matters in Durham

Historic to Modern

Durham's diverse housing stock ranges from historic homes to modern builds, each requiring different HVAC approaches and solutions.

Bull City Summer Heat

The Bull City's hot, humid summers with temperatures often exceeding 90°F demand reliable AC systems with proper maintenance schedules.

Retrofitting Challenges

Many older Durham homes have ductwork that wasn't designed for central AC, requiring creative solutions and expert retrofitting.

Outdoor Unit Care

Durham's tree-lined neighborhoods provide shade but also shed debris that can clog outdoor AC units, requiring regular cleaning and maintenance.

Common heating issues in Durham

Mixed Heating Infrastructure Across Neighborhoods

Durham's older areas (Hope Valley, Forest Hills, Duke Park) often have gas furnaces, while newer suburbs rely on heat pumps. Each system type has distinct maintenance and replacement needs.

Aging Gas Furnaces in Historic Homes

Gas furnaces in Durham's pre-1990 homes are 30+ years old in some cases, with declining efficiency and potential safety concerns from aging heat exchangers.

Duct Leaks Wasting Heated Air

Leaky ductwork in Durham's older homes wastes a large share of heated air, making the heating system work much harder and driving up Duke Energy costs during winter months.

Dry Air in Winter

Older, leakier Durham homes pull in cold, dry outside air all winter, which leaves indoor air dry enough to cause static, discomfort, and gaps in hardwood floors. Sealing air leaks helps, and a whole-home humidifier is an option for some systems.

FAQ

Heating in Durham: questions answered

Answered by our licensed technicians serving Durham.

What type of heating is most common in Durham?

It varies by neighborhood age. Pre-1990 Durham homes often have gas furnaces, especially in areas with established gas infrastructure. Homes built after 2000 predominantly use heat pumps. Durham's housing diversity means we work with all heating system types daily.

Is my Durham gas furnace still safe to operate?

Gas furnaces over 20 years old should be inspected annually for cracked heat exchangers and proper combustion. We use specialized diagnostic equipment to check for carbon monoxide leaks. If your Durham home has a gas furnace built before 2000, we recommend scheduling a safety inspection.

Should I switch from gas to heat pump in Durham?

Modern heat pumps can be more cost-effective than gas in Durham's mild winter climate, but the answer depends on your gas rates, electricity rates, and home insulation levels. We provide a cost comparison analysis specific to your Durham home so you can make an informed decision.

How can I heat my Durham home more evenly?

For Durham homes with uneven heating, solutions include zone control systems, duct sealing and balancing, or supplemental ductless mini-splits for problem areas. We evaluate your specific situation. Older Durham homes often get the biggest improvement from duct sealing alone.
