Heat Pump Installation & Repair in Pittsburgh

Cold-climate heat pumps, dual-fuel systems, and ductless mini-splits — installed and serviced by Pittsburgh's local heating and cooling experts.

About Our Heat Pumps Service

Heat pumps deliver year-round heating and cooling from a single system and are increasingly popular in Pittsburgh thanks to federal tax credits and rebates. Liberty Heating & Cooling installs and services air-source heat pumps, cold-climate models built for Western PA winters, dual-fuel hybrid systems paired with a gas furnace, and ductless mini-splits for additions or homes without ductwork.

Heat pump adoption in the Pittsburgh metro is picking up fast, especially in Plum, Murrysville, and Monroeville where larger homes on multi-acre lots benefit from dual-fuel hybrid systems. We've installed cold-climate Mitsubishi, Bosch, and Carrier Infinity heat pumps that maintain capacity down into the single digits — performance that wasn't possible from a heat pump even five years ago.

In older Oakmont and East End homes that never had central AC, ductless mini-splits are often the only sane retrofit option. We're factory-trained on Mitsubishi and Fujitsu mini-splits and can spec single-zone or multi-zone systems that don't require tearing into plaster ceilings.

Signs You Need Heat Pumps

If any of these sound familiar, it's time to call a professional. The earlier we diagnose, the smaller the repair.

  • Heat pump runs constantly but doesn't keep up on cold days
  • Auxiliary / emergency heat strips running more than they should
  • Outdoor unit iced over and not defrosting
  • Loud humming, clicking, or hissing from the outdoor unit
  • Heat pump heats but doesn't cool (or vice versa) — likely reversing valve
  • Air handler blowing cool air in heating mode
  • Energy bill noticeably higher than a comparable furnace + AC neighbor

What's Included

  • Air-source heat pump installation and replacement
  • Cold-climate heat pumps (rated for sub-zero performance)
  • Dual-fuel hybrid systems (heat pump + gas furnace)
  • Ductless mini-split installation (single and multi-zone)
  • Heat pump repair, refrigerant service, and defrost board replacement
  • Sizing, load calculations, and rebate paperwork assistance
  • Annual maintenance and seasonal changeovers

Our Heat Pumps Process

  1. 1

    Manual J load calculation

    Heat pumps are unforgiving of oversizing. Before we quote a replacement we do a real load calc, not a rule-of-thumb sizing.

  2. 2

    Cold-climate rating review

    We check the heat pump's capacity at 5°F and 17°F — the numbers that actually matter in Pittsburgh — not just the nameplate rating at 47°F.

  3. 3

    Backup heat strategy

    Pure heat pump, dual-fuel with a gas furnace, or electric strips — we walk you through which makes sense for your fuel rates and home.

  4. 4

    Rebate and tax credit paperwork

    We help you identify federal 25C tax credits and utility rebates and provide the AHRI certificates and invoices you need to claim them.

  5. 5

    Commissioning and verification

    After install we verify refrigerant charge, airflow, and defrost cycle operation, then walk you through thermostat setup for heat pump operation (which is different from a furnace).

Frequently Asked Questions

Do heat pumps work in Pittsburgh winters?+

Yes. Modern cold-climate heat pumps maintain full heating capacity down to about 5°F and continue producing heat below 0°F. For homeowners who want a backup, a dual-fuel system pairs a heat pump with a gas furnace that takes over on the coldest days.

How much does a heat pump cost installed in Pittsburgh?+

Heat pump pricing depends on the type of system, your home's size and layout, and any electrical or ductwork upgrades needed. Standard air-source units and cold-climate models are different investments. We also help you identify federal tax credits and utility rebates that can significantly reduce the net cost, and we provide a free, written quote before any work begins.

Are there rebates or tax credits for heat pumps?+

Yes. The federal Energy Efficient Home Improvement Credit (25C) offers up to $2,000 for qualifying heat pumps, and many Pennsylvania utilities offer additional rebates. We help you identify which systems qualify and provide the paperwork you need.

What's the difference between a heat pump and a furnace?+

A furnace burns fuel (usually natural gas) to create heat. A heat pump uses electricity to move heat from outside air into your home — and reverses in summer to provide cooling. Heat pumps are more efficient and replace both your furnace and AC.

How long do heat pumps last?+

With annual maintenance, a quality heat pump in Pittsburgh typically lasts 12–18 years. Mini-splits often last 15–20 years because they cycle less aggressively.

Will I be cold with just a heat pump in a Pittsburgh winter?+

Not if it's properly sized and a true cold-climate model. Modern variable-speed heat pumps from Mitsubishi, Bosch, Carrier Infinity, and Trane XV-series maintain full heating capacity into the single digits. For homeowners who want a belt-and-suspenders setup, a dual-fuel system with a backup gas furnace handles the few sub-zero days each year.

How does a heat pump compare to a furnace on operating cost?+

It depends on your electric and gas rates. In most of the Duquesne Light territory at current rates, a cold-climate heat pump runs slightly cheaper than an 80% AFUE gas furnace and roughly even with a 95%+ AFUE unit, plus it provides cooling. We'll run the actual numbers for your address.

Can I add a mini-split to just one room?+

Yes — single-zone mini-splits are perfect for additions, sunrooms, finished attics, bonus rooms over garages, or any space your central system never quite reached. Install is usually one day and doesn't require ductwork.
