Ryan g very professional explain things to me very helpful
Mike was very professional and knowledgeable. He explained reason for repairs. He left everything clean after his work. I would be happy to recommend and use his service for future needs. Also Princeton Air responded very quickly to my call and arrived within the time frame they said that they would. Iโ€™m not sure what the going rates are for this type of repair so the cost charged may be within reason. However, it seemed high priced.

Thermostat wasnโ€™t working Dominic from Princeton air explained very well and fixed right away. It was very educational. Thanks Dominic
I engaged Princeton Air for my Furnace maintenance. Danielle, the Technician was fabulous. Very patiently he explained to me in details the exact state of the furnace. No hard sell, just simple facts. I knew that am in good hands as he went on performing maintenance and clearly showed me what he was doing and why. I never experienced such a knowledgeable technician. He also gave me some tips to keep my HVAC system efficient. I highly recommend Princeton Air and specifically Danielle to any homeowner who wants peace of mind in running HVAC system efficiently

Princeton Air sent someone out the day I called, when another company said it would be a week – to find a leak source under my kitchen floors! The techs (2 of them) were great. Efficient, communicated what they found (refrigerator ice maker line) and how they were fixing it, and made sure the work was done correctly. Very reasonable price – would highly recommend Princeton Air.

I recently experienced issues with both my heating and cooling systems due to a power surge. As always, Ryan G. and Dave G. came to save the day. There were multiple issues discovered;Ryan spent two days at my home working on things and came back an additional two with Dave to complete the work. Really appreciate these gentlemen and their knowledge/Professionalism! I have used this company since they were Weltman and trust them to get the job done efficiently every time.

Comprehensive Heating Services

At Princeton Air, we specialize in a full range of heating services to keep your system running efficiently:

Furnace icon

Furnaces

For many New Jersey homes, the furnace delivers steady, reliable heat when it matters most.

When something feels off, it can disrupt more than temperature. It affects your sense of ease at home. Princeton Air cares for furnace systems with a focus on safety, longevity, and thoughtful performance, so your home remains warm and dependable.

  • Furnace Installation: A furnace should fit your home, not the other way around. For homes across Morristown and the surrounding area, we evaluate how your home holds heat, how air moves, and where inefficiencies exist before recommending a system. Installation is handled with precision and full code compliance, ensuring quiet, even warmth without strain or waste.
  • Furnace Repair: Furnace issues are often symptoms of something deeper. Princeton Air identifies the cause, corrects it thoroughly, and stabilizes the system so you’re not dealing with repeat issues weeks later.
  • Furnace Maintenance: Consistent care keeps your system dependable. Furnace maintenance from Princeton Air goes beyond a quick check. We clean, calibrate, and verify safe operation so your furnace performs reliably when you need it most.
  • Furnace Replacement: When repairs become frequent or performance declines, replacement becomes an opportunity. Homeowners in Maplewood and Mount Laurel who’ve carried aging furnaces through multiple winters often find that a modern system delivers more consistent heat, improved efficiency, and quieter operation without overcomplicating the decision.
Heat pump icon

Heat Pumps

Heat pumps offer a more balanced, efficient way to care for your home, but only when they’re properly designed and supported.

When they’re not, comfort can feel uneven or unpredictable. With our heat pump services in New Jersey, Princeton Air brings that balance back, so your home feels consistently right in every season.

  • Heat Pump Installation: We design systems that match your home’s layout and demands, not just square footage. For properties in Bedminster and similar communities where layouts vary widely, the result is a heat pump that maintains even temperatures, operates quietly, and supports long-term efficiency.
  • Heat Pump Repair: When performance drops, you may notice subtle signs like longer run times, weaker airflow, and inconsistent temperatures. Princeton Air identifies where the system is losing efficiency and restores it with targeted, lasting repairs.
  • Heat Pump Maintenance: Because heat pumps run year-round, they require a higher level of care. Princeton Air keeps components clean, settings optimized, and performance steady so your system doesn’t gradually lose effectiveness.
  • Heat Pump Replacement: Modern heat pumps offer meaningful improvements in comfort and efficiency. For homeowners in Plainsboro and across the service area, we guide you through the options clearly, helping you upgrade without guesswork or unnecessary complexity.

Oil-to-Gas Conversions

If your home still relies on oil heat, rising fuel costs and storage concerns often push the question of whether natural gas would serve the house better.

Princeton Air manages the full conversion, from system design and removal through installation and permitting, with everything handled properly inside your home.

Ductless system icon

Ductless Mini-splits & VRFS

Some homes and some spaces need a more tailored approach to comfort.

Ductless systems provide that flexibility, offering precise control without invasive installation. When designed properly, they quietly solve comfort challenges without disrupting the character of your home. Princeton Air offers complete ductless services for homeowners across New Jersey.

  • Ductless Mini-Split Installation: Placement matters as much as the system itself. Princeton Air designs ductless solutions across Chatham and similar communities that integrate cleanly into your space, delivering targeted comfort while maintaining a low visual profile.
  • Ductless Mini-Split Repair: When a unit isn’t performing as expected, the issue is often overlooked or misread. When you call Princeton Air for ductless repair, we diagnose accurately and restore performance without unnecessary adjustments or disruption.
  • Ductless Mini-Split Maintenance: Keeping filters, coils, and components clean ensures your system runs quietly and efficiently. Regular service from Princeton Air protects both performance and indoor air quality.
  • Ductless Mini-Split Replacement: Upgrading a ductless system is an opportunity to refine comfort even further. For homes in West Windsor and across the service area, newer systems offer better control, quieter operation, and improved efficiency, allowing each space in your home to feel exactly how you want it to.
  • Multi-Zone Ductless Design: When a home has several rooms with different comfort needs, a multi-zone ductless system gives you independent control in each space. We design these systems carefully, matching capacity to the actual demand in each room rather than installing the same unit everywhere.
Boiler icon

Boilers

Boiler heat is different from forced-air heat. It’s quieter, more even, and more subtle.

When it’s working properly, you hardly notice it. When it’s not, the discomfort feels deeper. Princeton Air’s New Jersey boiler services preserve that quiet reliability while ensuring your system operates safely and efficiently.

  • Boiler Installation: Boiler systems demand precision. From piping layout to pressure balance, every detail matters. Princeton Air installs new boilers across Hopewell and the surrounding communities with a methodical approach that protects both performance and longevity.
  • Boiler Repair: Boiler issues can be complex and are often misdiagnosed. Princeton Air technicians take the time to assess the full system and resolve the issue in a way that restores consistent, even heat without compromising safety.
  • Boiler Maintenance: Routine service helps prevent pressure problems, inefficiencies, and unexpected failures. Boiler maintenance from Princeton Air keeps your system tuned and monitored so it continues to deliver the steady warmth you rely on.
  • Boiler Replacement: When a boiler has reached the end of its service life, continued repairs rarely pay off. In older homes across Lawrence Township with boilers that have been running for thirty years or more, modern replacement delivers better comfort, meaningfully lower fuel use, and the quiet reliability that made you choose a boiler in the first place.
Smart thermostat icon

Smart Controls and Thermostat Integration

An outdated or poorly configured thermostat leads to uneven temperatures, wasted energy, and constant adjustments that interrupt your day.

We pair heat pump systems with thoughtfully selected smart thermostats and home comfort controls designed around how you actually live.


By focusing on energy efficiency and expert craftsmanship, Princeton Air helps homeowners reduce energy costs while ensuring reliable heating performance.
