HVAC Service Built for Pittsburgh
Pittsburgh's winters are not forgiving. When temperatures drop into the single digits and river-valley dampness seeps through older brick walls, your furnace is not just a comfort issue — it is a safety one. Air Pure Inc provides residential and commercial heating and cooling service across the Greater Pittsburgh area, with the kind of familiarity that only comes from decades of working on the city's older housing stock, tight basement stairwells, and the specific demands of climate zone 5A.
The Molnar family has been doing this work for three generations. That history shows up in the details: a technician who can look at a pre-1960s duct system and know immediately what it needs, a crew that understands how quickly a South Hills duplex or a Bloomfield row house can turn uncomfortable when a heat exchanger cracks in February. The goal on every visit is to explain what was found, show you the evidence, and give you a clear recommendation — not a sales pitch.
Air Pure serves both residential customers and commercial property owners, handling everything from furnace and AC repairs to full system installations. All work is performed to Pennsylvania Uniform Construction Code standards, with ACCA Manual J load calculations completed on new and replacement installations. Licensed and insured technicians are available around the clock for emergency calls, because HVAC failures rarely happen at a convenient time.

Common questions
Answers to what clients typically ask before getting in touch.
- How do I know if I actually need a new system, or if a repair will hold for a few more years?
- That answer depends on the age of the equipment, the nature of the failure, and what a repair would cost relative to the system's remaining value. A technician will walk you through that calculation honestly after diagnosing the problem. If a repair makes financial sense, that is the recommendation. If the system is approaching the end of its useful life or a key component like a heat exchanger has failed, you will hear that clearly, with the reasoning explained.
- What actually happens if my furnace dies in the middle of the night or on a weekend?
- Emergency service is available 24 hours a day, seven days a week, including holidays. When you call, a technician is dispatched to your home — not a call center, not a scheduling queue for the next business day. Pittsburgh winters leave little room for delay, and a furnace failure in a home with elderly family members or young children is treated accordingly.
- Will I know what this is going to cost before any work starts?
- Yes. After the technician diagnoses the issue, you receive a clear price for the repair before anything is touched. There are no surprise charges added after the fact. If the scope of the problem changes once the system is opened up, that is communicated to you immediately, and you decide how to proceed.
- Are you licensed and insured, and can you pull permits for work in Pittsburgh?
- All technicians are licensed and insured, and permits are pulled through the City of Pittsburgh Department of Permits, Licenses and Inspections when required. ACCA Manual J load calculations are completed on all new and replacement installations to meet Pennsylvania Uniform Construction Code requirements. The permit and inspection process is coordinated as part of the job.
- Do you work on commercial buildings, or is this just for homeowners?
- Both residential and commercial properties are served. Commercial work includes light commercial systems, multi-zone setups, ductwork design, and service for office buildings, retail spaces, and mixed-use properties. Facilities managers who need reliable maintenance scheduling and fast turnaround on repairs are welcome to call and discuss their specific setup.
- I have an older system from a brand you might not carry. Can you still work on it?
- All major HVAC brands are serviced, including older equipment. There is no requirement to switch to a particular brand or product line. If a replacement is genuinely the better path, the recommendation will explain why and include options across multiple manufacturers so you can choose what fits your home and your budget.
