At Chason Services, we know how much a reliable furnace matters when the temperature drops. With 80 years in the HVAC industry, our team installs, repairs, maintains and replaces gas, electric and oil furnaces, so your home stays warm, safe and efficient all winter.

A full inspection, not a quick look. Whether you call us for a repair, a tune-up or a replacement quote, we go through the whole system. We don’t glance at it and tell you that you need a new unit. If it can be repaired and maintained so it lasts, we’ll tell you.

Signs Your Furnace Needs Service

  • Higher energy bills or a house that won’t heat evenly.
  • Banging, clanging, rattling or squealing, which can mean delayed ignition, loose parts or a failing blower motor.
  • Uneven heating. Rooms that are much warmer or colder than others suggest airflow, ductwork or sizing problems.
  • More dust in the house than usual, which can mean filter or duct problems.
  • Frequent cycling or a furnace that won’t stay lit.
  • Yellow or flickering burner flames, soot, or a carbon monoxide alarm. If your CO alarm goes off, leave the house and call 911 or your gas utility, then call us.

Furnaces in Baltimore County Homes

Homes around Timonium burn many different fuels. Neighborhoods with natural gas service usually have gas furnaces. Many homes in the northern parts of the county, such as Sparks, Monkton and Upperco, don’t have gas lines and rely on oil or propane. All-electric homes often use an electric furnace or air handler paired with a heat pump. Older homes may also have a furnace that has been replaced several times over the original ductwork. Our technicians have worked on all of these setups for decades. Winter air in Maryland can be very dry, so adding a whole-home humidifier to your furnace can make the house more comfortable.

What Affects Furnace Costs?

Repairs include a diagnostic fee, and the rest depends on the part that failed, your furnace’s age and how easy parts are to get, and whether manufacturer warranty or Comfort Protection applies.

New furnaces depend on:

  • Fuel type (gas, oil, propane or electric)
  • Size (BTU capacity) for your home’s heat loss
  • Efficiency (AFUE) and features like two-stage or variable-speed blowers
  • Venting changes (high-efficiency furnaces use PVC venting and need a condensate drain)
  • Ductwork condition
  • Whether you’re also replacing your AC or adding a heat pump

BGE rebates, handled for you: if your new furnace qualifies for a BGE rebate, our office fills out and files the paperwork for you. See our current coupons.

Furnace FAQs

How often should my furnace be serviced?

Once a year, ideally in early fall. Regular tune-ups help prevent breakdowns and catch safety problems early.

Can I repair my furnace myself?

You can replace the filter and check the thermostat and breaker. Gas, electrical and combustion repairs should be done by a trained technician.

What should I do if my furnace stops working?

Check the thermostat, filter and breaker. If the furnace still won’t run, turn it off, avoid DIY fixes, and call Chason Services at (410) 252-6300.

How long does a furnace last?

Many furnaces last 15–20 years with regular maintenance. Past that age, efficiency drops and repairs become more frequent.

How long does furnace installation take?

Most furnace replacements are finished in about a day. Fuel conversions or ductwork changes can take longer. We’ll give you a timeline up front.
