HVAC Services in Wilmington, DE
Lumen Heating & Cooling brings fast, professional HVAC service to Wilmington and northern Delaware — and we help you tap into valuable Energize Delaware rebates on high-efficiency upgrades.
Heating & Cooling Services in Wilmington
Wilmington blends historic rowhomes and brick twins with suburban neighborhoods, each with different comfort needs. From boiler and radiator systems in older city homes to modern heat pumps in the suburbs, we install and service it all — and walk you through the Energize Delaware rebates that can lower the cost of a new system.
From emergency repairs to brand-new installations, our licensed, insured technicians — each with 10+ years of experience — handle it all for Wilmington homeowners and businesses. We speak English, Arabic & Spanish, offer upfront pricing, and back new systems with financing and a 10-year manufacturer parts warranty and 5-year labor warranty.
What we see in Wilmington homes
Wilmington is brick rowhomes and twins in neighborhoods like Trolley Square, Little Italy and the Highlands, larger 1920s–50s singles north toward Brandywine Hundred and Talleyville, and newer townhomes on the Riverfront. The older rows run boilers and radiators or converted furnaces; the northern neighborhoods are mostly gas forced-air with central air that's reaching replacement age. The reviewed job on this page — two complete systems, one in Broomall, PA and one in Wilmington — is typical of our Delaware work.
Delmarva Power serves electric, and Delaware rebates run through Energize Delaware's Home Performance with ENERGY STAR program: up to $1,600 on a ducted heat pump, $550–$1,100 on mini-splits, $650–$1,250 on central AC and $350–$750 on a 96%+ furnace, all after a $50 home energy assessment. We reach Wilmington from Philadelphia by I-95 in about 40 minutes and cover Brandywine Hundred, Claymont and Elsmere from the same run.

Straight From Google
“I'm not usually one to write reviews, but my experience with Lumen Heating and Cooling was so exceptional that it demanded one. … Mark personally called me the same evening I submitted my inquiry. His team arrived the next day and resolved every problem with both units. Their workmanship was precise, clean, and thorough. They treated me and my family with genuine care, delivered results that far exceeded expectations, and stood behind their work long after the job was finished.”

Mark came out to Cherry Hill, NJ to service my unresponsive unit.. I have a 4 year old & 10 month old at home; needless to say repairing was super necessary & we needed it done fast. He came through with a proper diagnosis & thorough assessment of the entire unit & problem. Prompt, professional & trustworthy, your search stops here... call Lumen & get your unit working again. I'd give more stars if I could!

Mark and team did a great job. We lost heat during the coldest week of the year and he came out immediately and did an urgent installation and was flexible about scheduling. He was fair and transparent about price and really clear about what he was doing. We definitely plan on working with him in the future if other repairs are needed. Highly recommend!

I honestly never write reviews, but Lumen absolutely deserves one.
I needed a new gas furnace and they were fast, professional, and had the best price by far. I shopped around, got multiple quotes, and nothing even came close. From the first call to installation, everything was smooth and stress-free.
The team showed up and got the job done quickly. No pressure, —just honest, quality work.
If you're searching around like I was, stop searching and call them ASAP. You won't do better.

Thank you for fixing the blower on our central air unit within days in the middle of a heat wave. You were very professional and did an amazing job! I would highly recommend!

They were quick and efficient at installing a new Mini split in our home. Their prices were good and their work was high quality. They were communicative, transparent and professional. Would definitely recommend them.

Lumen Tech was very nice. I had a used heater installed by another company and it didn't work, my place was freezing. Lumen came in and fixed the problem in one day. My house was warm and I'm happy now. Thanks Lumen :)
