What a new HVAC system costs in Crafton
Crafton is a borough where homeownership is common and the housing is overwhelmingly older, with most homes built before 1980 (U.S. Census Bureau, ACS 2024). That reality means HVAC work here is rarely a simple swap—this is a retrofit and replacement market. Many systems have been replaced or patched over the years, but the underlying duct jobs often date to the era of coal furnaces or early oil heat. Ducts are frequently tight, sometimes undersized, and rarely sealed by modern standards. Replacing or upgrading your central AC, heat pump, or going ductless in Crafton is usually about fitting new equipment to a ninety-year-old house—and its challenges.
Southwestern Pennsylvania is a heating-dominated climate with 5,600 heating degree days but just 1,050 for cooling. Winters can touch single digits. Heating is the main energy load for local homes, which should drive both equipment choice and efficiency priorities. While air conditioning matters for comfort, heating is what determines annual costs and system realities—especially where fuel choices and electric capacity can be constraining in older properties.

SEER2, HSPF2 and AFUE decoded
SEER2, HSPF2, and AFUE are efficiency ratings for HVAC systems, and each tells you how much heating or cooling you’re getting for your utility dollar. SEER2 (Seasonal Energy Efficiency Ratio 2) rates air conditioners and air source heat pumps for cooling—the higher it is, the more cooling per watt-hour. HSPF2 (Heating Seasonal Performance Factor 2) works for heat pumps during heating mode, measuring delivered heat per watt-hour used. AFUE (Annual Fuel Utilization Efficiency) applies to furnaces, showing what percentage of fuel gets turned into heat for your house; 95% AFUE means only 5% of heat escapes up the flue.
For Crafton, with 5,600 heating degree days and 1,050 cooling degree days, the math says heating efficiency impacts bills much more than cooling. That means HSPF2 and AFUE value stretch further than splurging on a super-high SEER2 AC. Typically, you’ll see payback on mid- to upper-tier HSPF2 or AFUE units (e.g., 9–10 HSPF2, 92+/95% AFUE) over the life of the system. Pushing SEER2 over 18 rarely pays off here unless you run central air constantly, which is uncommon. If you find articles quoting SEER or HSPF directly, know the ratings changed in 2023—SEER2 and HSPF2 use new test protocols and can’t be directly compared with older numbers.
Operating cost, not sticker price
Sticker price is just the start—the annual cost to heat or cool your Crafton home often matters more over time. To see how it shakes out, you combine your system’s efficiency rating (SEER2, HSPF2, or AFUE), your home’s heating and cooling degree days, and the utility rates from your actual Duquesne Light Company or gas bill.
Here’s how the comparison works: a heat pump’s HSPF2 rating tells you how many BTUs it delivers per kilowatt-hour. Multiply that by the annual heating load (in BTUs), which is based on our 5,600 heating degree days. For cooling, SEER2 translates the required cooling load (with 1,050 degree days) into annual kilowatt-hours. Finally, multiply by your electric rate—find it on your Duquesne Light Company bill—to see your real annual operating cost. For fuel systems, multiply the heating load by efficiency (AFUE) and the price per therm or gallon. If you don’t know your load, estimate loads for a 1,800-square-foot Crafton home, but remember envelope and ductwork make big differences.
But no math beats reality: utility rates can change, and a home with leaky, uninsulated or badly sealed ducts will waste a chunk of what you’re paying to make in the first place. Even a 20 SEER2 system gives little benefit if half the cooled air escapes into the attic. That means investing in sealing and testing your Crafton ductwork can often outperform jumping to the highest nameplate efficiency system.
What a Pennsylvania HVAC contractor must hold
Pennsylvania does not issue a statewide HVAC license for residential work; instead, contractors must be registered as Home Improvement Contractors for jobs over $500. For Crafton residents, this is regulated at the municipality level—your contractor must be properly registered and permitted with the local authorities for HVAC installation or replacement. The state sets the residential building code, but actual enforcement is by the municipality; in the City of Pittsburgh, mechanical permits are required for any new installation, replacement, or major alteration.
The only universal federal credential is the EPA Section 608 certification, required for any technician handling refrigerant. Always ask to see this. When refrigerant is involved, no license or permit substitutes for proper 608 certification.
For insurance, all employers must carry workers' compensation; you can verify a company’s coverage through the WCAIS system. Don’t take a verbal assurance—get a certificate in hand. Likewise, verify Home Improvement Contractor registration at hic.attorneygeneral.gov, especially for contracts over $500, which require a written agreement and offer you a mandatory three-day cancellation window. Skip any company unwilling to clearly show proof of registration, insurance, and local permits.
Why your ducts may be the real problem in Crafton
If you live in a pre-1960 home in Crafton, your ductwork is likely the weak link in your comfort and energy bills. Duct leakage in older systems can be so severe that 20–40% of conditioned air never makes it to your rooms—that’s a bigger impact than choosing between high and mid-tier efficiency equipment. Duct blaster tests are the standard for finding these leaks, measuring exactly how much air escapes under pressure. Without this test, sealing is just guesswork.
Returns are commonly undersized in older Crafton homes. That means not enough air can circulate back to your furnace or AC, causing noisy airflow, temperature fluctuations and system strain. In many older properties, ducts serving upper stories run through unconditioned attics or crawlspaces, so even perfectly sealed ducts end up losing heat or picking up moisture—another hidden source of inefficiency.
Many homes in this market never had central ducts, or the ducts are a patchwork retrofit sized for an 80% furnace, not a modern variable-speed heat pump. If a system was sized on visible ductwork but never tested, it’s very possible you’re running high bills for mediocre comfort. The honest step: test and seal (or replace) your ducts before you invest in new HVAC equipment. Anything less wastes the potential of your new system.
What size system does a Crafton home need?
Sizing is where a lot of Crafton installations go wrong. Getting a system that’s too large for your home isn’t a bonus—it leads to short cycling, uncomfortable temperature swings, poor summer dehumidification, and shorter equipment life. It also means you’re paying for capacity you won’t use, every time that system turns on for a minute, then off again.
No responsible contractor sizes your equipment by “rule of thumb” or copies from the placard on your old unit. The only correct approach is a Manual J load calculation, which models your home’s unique size, insulation, windows, and air leaks against Crafton’s specific climate. This means using our winter design temperature of 8 °F as the benchmark so your new system will keep up even on the coldest days. If your contractor can’t show you the load calculation (and how it relates to our actual climate), you’re getting a guess—not a professional proposal.
If you ask, “Did you run a load calculation, and can I see it?” and the answer is no, you’re not getting value. Getting sizing wrong is the single fastest way to throw money away on new HVAC, and it happens all the time in retrofit-heavy, older Crafton homes.
What a real HVAC quote contains
If a contractor’s quote is just a brand and a price, you have no shot at a real apples-to-apples comparison. A real quote for a Crafton replacement or retrofit will break down both the indoor and outdoor units with exact model numbers (they must be a listed matched pair), list the system tonnage and include the full load calculation, spell out what’s happening with your ductwork (assessed, tested, sealed or replaced), and specify what, if any, electrical upgrades or condensate handling are included. It details line-set replacement or reuse, thermostat type, permit fees, a startup report or commissioning checklist, and a clear labor warranty—separate from the equipment warranty.
Don’t accept missing information. Every legitimate quote should equip you to understand, compare, and make an informed choice.

Frequently asked questions — HVAC installation in Crafton
What MERV filter rating should I use?
In Crafton's older homes, it’s important not to choke off airflow with a filter that’s too restrictive for your system. Most homes do fine with a MERV 8 filter, which catches a meaningful amount of dust and pollen but is still easy for an older blower to pull air through. If allergies run strong in your family, you might consider MERV 11, but only if your system and ductwork are in good shape and the air handler is strong enough. Don’t be upsold to MERV 13 unless your system is specifically designed for it—too much restriction can lead to expensive repairs or reduced comfort. If you’re getting a full or ductless system replacement (which may run from $4,900–$11,500 or more), ask your installer what the equipment is rated for and whether an upgrade makes sense.
How cold does it get in Crafton and does that affect heat pumps?
Winters in Crafton can hit 8 °F or below during cold snaps, which is right at the region’s winter design temperature. Standard heat pumps may struggle to keep up efficiently in these conditions, especially in uninsulated or drafty homes. If you’re considering a heat pump, ask about cold-climate models—they’re engineered to deliver high output below freezing and often feature higher HSPF2 ratings (usually 9–11). While they cost on the high end (typically $12,500–$16,500 installed), they eliminate most need for backup heat and perform well even when our weather turns harsh. Never just trust a generic “heat pump” description for our local winters—ask exactly which model and how it’s rated at low temperatures.
How far ahead should I schedule in Crafton?
Crafton contractors are busy, especially during the first heat wave or cold snap. Most reputable outfits book out a couple weeks for replacement work, and specialty projects like full duct system installation (often $8,700–$17,500) can take longer. Emergencies get bumped up, but for routine replacement or upgrade, aim to book in early spring or fall—the shoulder seasons. Get your quotes and options in place before your system dies in peak season, when schedules get tight and prices can creep up. For specialty services (ductless, heat pump retrofits in older homes), planning ahead is even more critical. Don’t wait until it’s an emergency to start the process.
Do I need a permit to replace HVAC in Crafton?
Yes, if you live in an area under City of Pittsburgh code enforcement and your work involves new HVAC installation, replacement, or major alteration, a mechanical permit is required. Even in smaller Crafton neighborhoods, most municipalities enforce permitting for this scope. Permitting ensures the work is checked for code and safety, and may be required when you sell your home or update insurance. If your contractor says a permit isn’t needed for ducted HVAC replacement (often costing $7,800–$16,500), that’s a warning sign—you want the inspection for your protection. Always check permit status before work starts.
Why are my Crafton energy bills high with a new system?
High bills after a new installation are usually a ductwork or sizing issue, especially in Crafton’s older homes where ducts were rarely sealed or sized for today’s systems. Even a top-efficiency system, like a 20 SEER2 heat pump, can underperform if half the air leaks out before it ever makes it to your rooms. The cure is always diagnostic: run a duct blaster test and inspect for real losses. Ask your installer if sealing or upgrading your old duct system would lower your costs. Sometimes spending a few hundred dollars more on ductwork, even as part of a large project ($8,700–$17,500 for new ducts), saves much more year after year.
How is a tax credit different from a rebate?
A tax credit reduces what you owe on your federal or state tax return at the end of the year—if you install a qualifying HVAC system in Crafton, you claim the credit when you file taxes. By contrast, a rebate comes directly from a utility or manufacturer and usually pays out within weeks or months of purchase, reducing your net outlay right away. Both can apply to new systems (such as certain air source heat pumps, which often cost $7,800–$16,500), but the paperwork and timing differ—credits require patience, rebates help cash flow sooner. Always confirm what’s available locally before making a final choice.
How much does ductwork add to an HVAC installation?
Full duct system installation in a Crafton home runs from $8,700–$17,500, depending on house size, number of runs, and whether space needs to be built out for new chases in older construction. Adding or replacing ducts in homes that never had central systems is a major cost driver—expect this if you’re upgrading from baseboard or only window ACs. For smaller fixes, like sealing and resizing returns in older ductwork, the cost is much lower but can still deliver outsized comfort and efficiency gains. Always ask for a duct evaluation before signing any equipment contract.
How much does a furnace replacement cost in Crafton?
While exact furnace pricing isn’t given in the local cost bands, you can use the central AC and ducted heat pump ranges as a proxy—a straightforward furnace replacement with existing ducts typically falls in the same mid-range as central AC, or $4,900–$11,500. High-efficiency or variable-speed models land higher. Unique to Crafton, homes often need some electrical updating or minor ductwork at the same time, which can nudge the price up. Get multiple quotes, and ensure your quote includes any required code upgrades or permits.
Do I need dual fuel in southwestern Pennsylvania?
Dual fuel systems (pairing a heat pump with a backup gas furnace) can be attractive in Crafton, given our 8 °F winter design temps. They let you enjoy the efficiency of electric heating most of the season but automatically switch to gas on the coldest nights, protecting both comfort and bills. It’s not required—new cold-climate heat pumps now manage below freezing, but are pricier (around $12,500–$16,500 installed). If you have existing gas lines and want peace of mind on the coldest days, dual fuel offers flexibility. If you aim to avoid fossil fuels, go for a cold-climate model and invest in duct and envelope upgrades for best results.
