Typical published repair averages are about $125 to $480 for furnaces and $150 to $700 for boilers. Gas odor or a carbon-monoxide alarm means leave the building and call the utility or 911 first.

  2. Match the system type and service need
  3. Diagnose before approving repair work
  4. Verify safe operation, venting, and temperature delivery

What is different about Wilmington properties?

Wilmington homes include steam and hot-water boilers, gas and oil furnaces, electric systems, and modern heat pumps. Older piping, chimneys, fuel conversions, and mixed additions require system-specific judgment, so tell the dispatcher exactly what you have.

Verify before work begins.

Ask the responding provider for identity, applicable Delaware license information, a written diagnosis or scope, total price, and warranty terms.

Historic Steam Boiler Service

Quiet radiators and proper steam balancing

Our 1920s brick home had banging steam pipes and cold second-floor radiators. Finding someone who understands older steam systems in Wilmington is tough. The provider cleaned the sight glass, replaced three stuck air vents, adjusted the pressuretrol setting, and explained how to skim the boiler. The house is finally quiet and evenly warm.

Gas Furnace Diagnostic & Repair

Honest diagnostic and zero sales pressure

Our furnace was short-cycling and shutting off after 5 minutes. Another company insisted we needed a whole new system immediately. The provider matched through this site inspected the pressure switch, cleaned a clogged condensate trap, and tested the draft. Fixed the issue for a fraction of the cost without pressure tactics.

Heating Tune-Up & Safety Check

Thorough combustion analysis and peace of mind

Moved into an older twin near Baynard Boulevard and wanted our gas heating checked before winter. The technician tested for carbon monoxide, inspected the heat exchanger with an inspection camera, and tested all safety limit controls. Clear explanations throughout.

Common questions

Clear answers before you call

What should I do if I smell gas?

Leave the building, avoid switches or flames, and contact the gas utility or emergency services from a safe location. Do not wait for a routine HVAC appointment.

Why does my heat pump sometimes blow cooler air?

Heat-pump supply air often feels cooler than furnace air. Defrost cycles are also normal, but persistent discomfort, auxiliary-heat problems, or unusually high bills deserve diagnosis.

Do you handle boilers and oil heat?

Requests are matched by system type and provider availability. State clearly whether the system is steam, hot water, oil, gas, or electric.

My unit is 19 years old and a technician said it is too old to service. Is that true?

Age alone does not make a system unserviceable; most parts remain available. Ask for the specific failure and a repair price, and get a second opinion before replacing a working system.
