Why Dalton Heating & Air Is Westerville’s Preferred Furnace Repair Company
Marco Benitez leads our team, and he’s built our Westerville reputation on a simple rule: diagnose the actual fault before recommending anything. That discipline is why homeowners here keep our number after the first call. Every job carries a written price before any work begins, and every repair is guaranteed in writing for a full year. If the repair fails inside those 365 days, we return and make it right at no charge. No fine print. No upgrade required.
Our technicians are background-checked and uniformed, so you know exactly who is coming before they arrive. They service nine major furnace and AC brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. For Westerville specifically, that matters because so many homes still run builder-grade Rheem or Goodman furnaces from the 1990s, and factory training on those specific units means we diagnose faster. A misdiagnosis costs you money. We’d rather spend an extra ten minutes testing than sell you a motor you don’t need.
Boiler Repair in Westerville
Boiler repair in Westerville means servicing the hydronic heating systems found in many of the city’s older homes and some newer custom builds near Hoover Reservoir. A boiler heats water and circulates it through radiators or baseboard heaters, and when a circulator pump or zone valve fails, the house cools unevenly and fast. Westerville winters put real strain on these systems, especially when a boiler has been running for 15-plus years without a proper annual service. Most boiler repairs in Westerville run $150 – $700, with common work including circulator pump replacement, zone valve repair, expansion tank service, and pressure switch replacement.
Circulator Pumps and Zone Valves
When one room stays cold while others heat normally, the problem is often a failed circulator pump or a stuck zone valve. These are mechanical parts that wear out with use, and a quick voltage test at the valve confirms the failure in minutes.
Expansion Tanks and Pressure Switches
Water expands when heated, and the expansion tank absorbs that pressure change. A waterlogged tank causes the pressure relief valve to drip, or worse, the boiler to shut down on a safety fault. We test and replace these before they take the whole system offline.
Gas Furnace Repair in Westerville
Gas furnace repair in Westerville is our most common winter call, and for good reason: the housing stock here is split between mid-century ranches with original 1950s – 1960s ductwork and large 1990s – 2000s builds that are now hitting the 20-25 year mark. A gas furnace that won’t fire, short-cycles, or blows cold air is often a failed ignitor, gas valve, flame sensor, or blower motor. Most repairs run $150 – $700, with straightforward parts like ignitors and flame sensors landing on the lower end and gas valve or blower motor replacement on the higher end. You get the price in writing before we start.
Ignitors and Flame Sensors
An ignitor glows to light the gas; a flame sensor confirms the burn actually happened. When either fails, the furnace locks out for safety, and your house slowly cools. We keep common ignitors and sensors on the truck for Westerville’s most popular furnace brands, including Trane, Lennox, and Goodman.
Gas Valves and Blower Motors
A gas valve controls the fuel entering the burners. A blower motor moves warmed air through your ducts. Both are bigger-ticket repairs but far cheaper than a full replacement, and our techs confirm the failure with a meter before recommending either.
Trusted Brands We Service in Westerville
We service and repair all major furnace brands in Westerville, including Trane, Lennox, Goodman, and Rheem. Our trucks carry a stocked inventory of common parts for these systems, so many repairs get done in a single visit. That’s the difference a local, brand-trained crew makes when your furnace dies on a Friday afternoon in January and the parts warehouse across town is closed. We don’t offer a generic fix; we fix the exact unit in your basement, and we stand behind the work.
Common Furnace Repair Problems We See in Westerville Homes
- Blower motor and capacitor failures on older builder-grade units. Many mid-century ranches in Westerville still run the original furnace motor, and a weak capacitor often gets labeled as ‘it’s just old’ by less thorough techs. A meter test tells us the real story in minutes.
- Heat exchanger cracks in 20-plus-year-old furnaces. Homes with undersized return ducts run hotter and stress the heat exchanger faster. A crack won’t always show on a visual check, but a combustion analyzer catches it, and that’s a safety finding we never ignore.
- Short-cycling caused by oversized equipment. We see furnaces in Westerville that were installed without a proper load calculation, so the unit heats the space too fast, shuts off, and kicks on again minutes later. Homeowners think it’s broken. It’s actually a sizing and static pressure problem.
- Ignitor and flame sensor failures during cold snaps. When temperatures drop hard across central Ohio, old ignitors and dirty flame sensors fail more often. The fix is usually quick if the parts are on the truck, which is why we stock for Westerville’s common brands.

FAQs About Furnace Repair in Westerville
Repair is usually the right call if the failed part is under $700 and your furnace is under 15 years old, but we recommend replacing when the heat exchanger is cracked or the unit is past 20 years and showing corrosion. For Westerville specifically, the age of your ductwork matters: a new furnace on undersized 1960s ducts won’t perform as promised, and we’ll tell you that before you spend anything. Call (361) 306-9515 for an honest assessment.
Short-cycling means the furnace fires, runs a few minutes, then shuts off before the house is warm, which in Westerville we most often trace to an oversized unit, a failing blower motor, or a capacitor out of spec. We tested a home off Cleveland Avenue where the blower motor was failing and the capacitor was weak; after replacing both and dialing in blower speed, the static pressure dropped from 0.9 to 0.55 and the system held temperature. If your furnace is doing this, don’t keep turning the thermostat up; call (361) 306-9515 and we’ll find the root cause.
SEER2 is the updated efficiency testing standard for air conditioners and heat pumps, measuring cooling output per watt consumed under more realistic conditions than the old SEER rating. For furnace decisions in Westerville, it matters less than AFUE, but when you’re weighing a full HVAC change, a higher SEER2 rating means lower summer electric bills for your AC, and we’ll match the right efficiency to your home, not just sell you the highest number. We’ll explain the math on your actual bill before you commit.
Furnace repair in Westerville runs $150 – $700 for common part replacements and labor, with a gas furnace diagnostic and capacitor replacement at $150 – $450. A boiler repair lands in the same $150 – $700 range, and a full tune-up with cleaning and safety checks is $80 – $200. The price is in writing before work begins. Call (361) 306-9515 for an exact quote, free.
A 1990s furnace that’s technically repairable is still at the point where the heat exchanger is the deciding factor; if it’s cracked or showing combustion stains, replacement is the safe and honest recommendation, not another band-aid repair. In Westerville, we see plenty of 1998 builder-grade units still running, and we’ll give you the repair-versus-replace numbers straight before any work happens. Call (361) 306-9515 and we’ll do a combustion analysis and give you our read.
If your furnace is down or acting up in Westerville, call (361) 306-9515 now. A live person answers 24/7, the estimate is free, and the price is in writing before any work begins.
