Heating and Cooling Done Right in Pittsburgh
Pittsburgh winters are not polite. When temperatures drop toward single digits and a furnace quits, the margin for a slow response disappears fast. Weidner Heating & Air Conditioning has been handling exactly those calls — and the humid July afternoons when a central air system stops keeping up — since 1957. The work covers residential and commercial customers across the Pittsburgh area, from older brick homes in Shadyside with tight basements and legacy ductwork to newer builds that need high-efficiency systems sized and installed correctly from the start.
Gerald Fabiszewski leads the work personally. When you call for a quote, Gerald comes out, walks through your space, and explains the options in plain terms — what's failing, what fits your home, and what the numbers actually mean. Customers consistently note that the estimate visit feels less like a sales call and more like a diagnostic conversation. That approach carries through every job, from a single-zone repair to a full furnace and air conditioning replacement.
As a Carrier Factory Authorized Dealer with NATE-certified technicians, Weidner meets a specific set of training and service standards that Carrier audits regularly. That matters in practical terms: it means the technicians working on your equipment have current, manufacturer-level training, and it means the Carrier equipment installed carries a 100% satisfaction guarantee. For homeowners weighing whether to repair an aging system or replace it, that kind of clear commitment to the outcome makes a real difference.

What our clients say
“The installers were prompt, professional and friendly. They were fast and very neat. They explained everything they were going to do I highly recommend Weidner for all your HVAC ..… Read more”
Mary Schirnhofer
“We had a mini split installed in our master bedroom back in April. My husband and I feel it was one of the best decisions weve made. It keeps the bedroom a perfect sleeping temperature and is whisper quiet. Our house air conditioner doesnt always keep the upstairs bedroom cool enough. This definitely does. Highly recommend the mini split and this company to install!”

Common questions
Answers to what clients typically ask before getting in touch.
- How do I know if I actually need a new system or just a repair? I don't want to be talked into something I don't need.
- Gerald gives you the honest read on both options before recommending anything. If a repair is the right call — cost-effective, safe, and likely to hold — that's what he'll tell you, with a specific explanation of what failed and why the fix makes sense. If replacement is the better long-term value, he walks through the numbers: repair cost versus efficiency gains, remaining equipment lifespan, and what the new system would actually cost installed. You'll have enough information to make the decision yourself.
- My furnace stopped working tonight. How fast can someone actually get here?
- Weidner maintains 24/7 emergency availability for exactly that situation. Pittsburgh winters don't accommodate a two-day wait, and a heating failure in a home with single-digit temperatures outside is a safety issue, not just an inconvenience. Call the main number and you'll reach someone who can dispatch Gerald or get a response scheduled for the earliest possible time — not a general window that stretches into the next day.
- What will this cost me in total — parts, labor, any fees — before you start the work?
- You'll get a clear, itemized estimate before anything is approved. For installations, the estimate is free and covers equipment, labor, and any permit fees required by your municipality. For service and repair calls, Gerald explains what he found and what the repair costs before picking up a tool. There are no surprise charges added after the fact.
- Are you licensed and insured, and can you pull the permits for this job?
- Yes on both. Weidner holds the HVAC contractor licensing required under Pennsylvania's HICPA framework and carries full liability insurance. Permit coordination for Pittsburgh and Allegheny County is handled as part of the installation process — you don't need to navigate the municipal requirements yourself or worry about a failed inspection down the road.
- Do you work on all brands, or only Carrier equipment?
- All major brands. Being a Carrier Factory Authorized Dealer means Gerald has specialized training and access to Carrier parts and guarantees, but repair and maintenance work covers whatever equipment is already in your home. You won't be told your existing system needs to be replaced simply because it isn't Carrier.
- Do you offer financing if I end up needing a full replacement and the cost is more than I planned for?
- Financing options are available for qualified customers on equipment installations. If a furnace or AC replacement turns out to be the right call and the upfront cost is a concern, ask Gerald about current terms during your estimate visit. He can also walk through any available rebates or federal efficiency tax credits that might apply to the system you're considering.
