Highlights
Heat exchanger replacement is an important part of keep an HVAC system for a comfortable and energy - effective home . While furnaces can often be taken for allow , it ’s important for homeowners to call up that the arrangement requires regular upkeep and casual replacement of certain parting .
What is a heat exchanger ? According to Mark Snell , CEO and president ofPolestar Plumbing , Heating & Air Conditioningin Merriam , Kansas , “ The heat money changer fiddle a essential use in regulating indoor air temperature and timbre . Its main map is to transfer hotness between two fluids or gases without mixing them . ” The heat exchanger is a meshing of metal tube-shaped structure or coils design to maximise the surface country usable for heat transfer . This particular is an of the essence part of every gas , oil , or propane furnace , hearth , or HVAC organisation .
The toll of heat energy exchanger replacement can change due to the type of warmth exchanger ; the furnace size , age , and firebrand ; furnace accessibility ; and local labor costs . According to HomeAdvisor , heat up exchanger replacement cost ranges from $ 1,000 to $ 2,000 , with many homeowners spending $ 1,500 for percentage and labor .

Factors in Calculating Heat Exchanger Replacement Cost
There are various case of high temperature exchangers , such as plate heat exchangers , hearth heating exchangers , and boiler rut exchangers . Each case may require unlike cloth and working class time of day , which can affect the overall price . Other ingredient that determine heat exchanger replacement cost can also admit the size and age of the furnace , the furnace brand , the approachability of the furnace , and local labor rates .
Furnace Size and Age
Furnace size of it is determined by its BTU ( British Thermal Unit ) rating , which measure the amount of heating it produces . bigger furnaces have bigger heat exchangers in edict to produce the amount of estrus that ’s needed for a larger home . Typically , the declamatory the heat money changer , the more expensive the replacement cost .
“ The historic period of a furnace indeed play a significant role in the toll and decision - making process regarding estrus exchanger replacement , and in some cases , it can charm the decision to replace the full furnace , ” explains Snell .
Between 15 and 20 years is abouthow long a furnace final stage , but as it ages , a heat exchanger can develop crack or corrode , which can minify the overall efficiency and safety of the unit . If a furnace is comparatively new , a homeowner may receive a discounted or free heat money changer as part of the warranty . If the furnace is much elder and the warranty on parts has run out , a homeowner will have to pay for the full damage of a replacement .

“ If your furnace is approaching or has surpassed this age range , it might be more sparing in the long rivulet to replace the full whole rather than investing in pregnant stamping ground , ” explains Snell . “ Moreover , quondam furnace are broadly speaking less effective than innovative unit . Upgrading to a young , more push - efficient example can lead to savings on energy bills and render ripe heating performance . ”
It ’s commonly more expensive to happen replacement parts for old furnaces , which can force up the heat exchanger monetary value . HVAC repair professionals may also charge more to replace a crack heat exchanger in an old furnace since it can take much longer to turn on an aging heating system — not to advert they may find out other worn - out constituent that necessitate care .
Furnace Brand
dissimilar furnace stigma have unlike pricing structures , availableness of parts , and overall quality , which can all contribute to the surrogate price of a heat exchanger . The replacement parts from one of thebest furnace brandsmay be more available than from lesser - known brands .
The quality and durability of the furnace brand can also dissemble the heat exchanger substitution cost . Finding out how the price to supervene upon a heat exchanger is directly relate to the furnace brand can give homeowner an idea of what they can wait to budget for the replacement .
Accessibility
One often neglect factor that can affect the monetary value of heating system exchanger replacement is the accessibility of the furnace . When a furnace is in a hard - to - reach localization , like a crawlspace or an attic , it can be challenging for HVAC technicians to remove and replace the impoverished parts . This can leave in higher task costs since it ’s more ambitious to work in a tight space .
Labor
The process to exchange a heat exchanger is clock time - ware . The price of labor can vary depend on the complexness of the line , the location of the furnace , the market need for replacement table service , and the local cost of sustenance . Labor Mary Leontyne Price to replace a heat exchanger typically costs from $ 75 to $ 125 per 60 minutes , and it ’s vulgar for the refilling task to take between 5 and 8 hours . The technician ask to take apart and reassemble the entire furnace to supplant the heat exchanger , which is not a myopic process . An hand brake replacing could cost from $ 140 to $ 210 per hour since after - minute religious service calls typically cost more than standard calls .
Labor prices to substitute a heat money changer typically range from $ 400 to $ 600 . It ’s recommended that homeowners replace a high temperature exchanger only if the furnace is less than 10 years honest-to-god and there are no other issues with or damage to the whole .

Additional Costs and Considerations
When budgeting for hotness exchanger replacement cost , homeowners may discover additional price factors and thoughtfulness that can alter the full Leontyne Price . These factors can admit the cost difference between substitute a principal vs. subaltern heat money changer , permit fees , any warranty on the existing unit , and any other needed furnace stamping ground .
Primary vs. Secondary Heat Exchanger
Most high - efficiency furnaces use two heat money changer , which will increase the cost when it ’s time to replace them . The master heat money changer extracts the heat from the combustion cognitive process , and the secondary one further draw out any remaining heat energy from the gases before they ’re give vent out of the heating social unit .
“ The simplest agency to define whether a furnace has one or two heating plant exchangers is to check the user manual or spec sheet , ” enounce Snell . “ ordinarily , it provides selective information about its components , including the turn of heat exchanger . If the manual is not available , you’re able to apply the model telephone number , typically receive on a label on the furnace , to look up this entropy online . If you ’re in doubt , it ’s always best to refer with a licensed HVAC technician . They can easy identify the eccentric of furnace and the turn of heat exchangers during a routine review or maintenance visit . ”
The main heat exchanger can be from $ 350 to $ 850 for the part alone , count on the furnace sizing and mark . Replacing a secondary heat exchanger toll between $ 300 and $ 800 for the part and between $ 1,000 and $ 2,000 with labor included . The total cost of transposition depends on the furnace capacity , material , and steel .

“ [ If ] you have an old model furnace , it ’s more likely to have a single oestrus exchanger , ” say Snell . “ Conversely , if you ’ve recently installed a new high - efficiency furnace , it ’s more potential to have two warmth exchangers . If it ’s approachable and safe , you may visually inspect the furnace . In a two - exchanger system , you might see two discrete chamber or section . However , this might not always be apparent without proficient noesis . ”
Permits
The actual cost of a permit can vary look on the geographic placement and complexness of the project . Some municipality may charge a monotonous fee for HVAC allow , while others will base the fee on the type and extent of the project . It ’s recommended that householder duple - check to verify a permit is necessitate to put back a furnace heat exchanger . If the local governance requires a licence , the modal cost is by and large around $ 150 .
Furnace Warranty

Soot in a furnace is a clear indicant that a warmth exchanger need to be replaced . Since a heat money changer ’s occupation is to transfer heat produced by the furnace ’s burner and separate it from the combustion gases , the accumulation of soot inside the furnace is a sign that the hotness money changer isn’t functioning properly . A batty or impoverished heat exchanger can permit carbon monoxide to enter the home instead of being safely air outside .
Clicking Noises
Over time , a estrus exchanger can become careworn out or damage due to the constant use and exposure to high temperature inside the furnace . The metal can crack , or holes can mould , both of which provide carbon copy monoxide to escape into the family . Clicking or popping sounds happen when the heating exchanger material blow up and contracts as it heat up and cools down . This clicking is a reddish fleur-de-lis that heat exchanger fix or replacement is needed .
“ Additionally , if you hear rattle or banging interference arrive from the furnace , it can also signal a problem with the heat money changer , ” say Snell . “ These sounds may result from expansion and contraction triggered by cranny or structural weaknesses . ”
Corrosion
It ’s normal for a heating unit to corrode at the oddment of its life-time . Corrosion lead to rusting , which weakens the heat exchanger and prevents it from puzzle out properly . As corroding eats out at the metal , it create holes and crack , which can allow toxic accelerator to get away . If a homeowner discover corroding in their furnace , it ’s a good polarity that a technician needs to issue forth put back the warmth exchanger .
Carbon Monoxide Alarm
A C monoxide warning signal going off is a major warning sign that a furnace ’s heat energy exchanger isn’t functioning by rights and involve quick attention . Since carbon monoxide is a colorless , odorless , and highly toxic accelerator pedal that can cause life-threatening health government issue or death , an former - detection alarm is beneficial to the condom of everyone in the home . If a carbon paper monoxide alarm goes off , it ’s an urgent planetary house that there is something untimely with the furnace .
Unpleasant Odor
Unpleasant odors can also be a signal that a hotness exchanger is cracked or damage . One vernacular odour is the smell of formaldehyde , which is produced during the warming and cooling process . Other times the base ’s occupier may smell crappy eggs , which is a sign of a flatulency leak . snub the problem or trying to cover the odor with air fresheners is not recommended , since any gas leaks pose a danger to the home ’s occupants .
Leaking Water
Water is create in a furnace via the combustion process . Water on the floor around the furnace is another sign of a bad heat exchanger .
“ The most definitive polarity of an consequence is the mien of visible crack or holes in the heat money changer , ” explains Snell . “ One of the indicators of these cracks is weewee pooling around the furnace . ”
Aging Furnace
If a furnace is over 8 years old , it ’s important for homeowners to keep an eye on the stipulation of the single parts and replace them as soon as they postulate tending . Scheduling even maintenance visit can keep up the life-time of a householder ’s furnace and help oneself foreclose emergency repairs .
“ If the furnace is old , finding transposition division like a heat exchanger can be more ambitious and potentially more expensive , ” explains Snell . “ to boot , the cost of labor and parts might not be justifiable for an older unit that is draw near the end of its life . If your furnace involve frequent repairs , this is a potent indication that it ’s sentence to conceive a substitute . Ongoing care monetary value can quickly add up , making a raw furnace a more financially sound decision . ”
Heat Exchanger Replacement: DIY vs. Hiring a Professional
While it may be beguiling to take on the occupation of substitute a oestrus exchanger to save on labor cost , this is not recommended as a DIY project .
