If you are researching boiler repair and installation in Hartly, get to know KelAire HVAC before you need us. Doug Kelley runs the company from Millington, Maryland, 30 minutes from Hartly, with the kind of reviews that only come from years of showing up and telling the truth. Delaware license reinstatement is underway, and we will open Hartly scheduling the moment it is active.

Hartly sits about 30 minutes from our shop in Millington, comfortably inside the radius we plan to cover. Hartly is quiet farm country in western Kent County, Delaware, with rural homes and small farms where heat pumps, propane furnaces, and mini-splits all have a place. It is precisely the kind of area our shop location was chosen to serve.

If you have lived in Hartly long, you already know: properties that bigger outfits from Dover or Wilmington often overlook. We build our recommendations around realities like that instead of pretending every house is the same.

What Hartly clients call us about most

  • A boiler decades past its expected life
  • A boiler losing pressure or leaking
  • Radiators or baseboard staying cold
  • Banging, gurgling, or kettling sounds
  • A pilot that will not stay lit
  • One zone heating while another sits cold

Work we perform every week

  • Expansion tank and pressure relief service
  • Circulator pump and zone valve replacement
  • High-efficiency boiler replacement
  • Air bleeding and system balancing
  • Gas and propane boiler repair
  • Boiler-to-heat-pump or hybrid conversions where they make sense

How We Approach the Work

A well-maintained boiler is one of the longest-lived heating systems there is, but small problems compound: a waterlogged expansion tank stresses the relief valve, trapped air starves a zone, a failing circulator masquerades as a thermostat issue. We diagnose the system as a system.

★★★★★

If you want your system done right or serviced with honesty, Doug is the guy! He truly knows everything about HVAC.

Why Hartly Should Know KelAire

KelAire is not a franchise and not a private-equity rollup with quotas to hit. Doug tries his best to repair before replacing, and more than one review mentions being told they did not need the expensive fix another company quoted. When replacement genuinely is the right call, you get options explained in plain language, with the tradeoffs laid out honestly.
