Whether your air conditioner stopped on the hottest day of the year, your furnace is cycling on and off in January, or you are planning a full system replacement for your home or business — this page is your starting point. GigoPro's HVAC hub gathers verified heating, ventilation, and air conditioning contractors from cities across the United States in one place, so you can stop calling around and start comparing on facts.
Every company you find here lists what it actually does: air conditioning repair and installation, furnaces and heat pumps, ductwork and ventilation, indoor air quality, commercial HVAC maintenance, and emergency call-outs. Each profile shows the services offered, the area the company serves, recent customer reviews with ratings, and contact details — so you can shortlist three or four pros, request written estimates, and book the one that fits you best.
Quality on Gigo is not self-declared. Before any business appears in search results, we moderate the profile: we verify that the company is real, actively operating, and actually operates in the category it claims; for regulated trades, we verify proper credentials. Listings that stop being active are hidden automatically. That is what "verified near you" should mean, and it is why tens of thousands of homeowners [replace with real number if available] start their HVAC search here every month.
Pick your city below to see local providers, ratings, and current availability — or read on to learn about the services, get a simple contractor-hiring checklist, and find out what to expect before you book.
The contractors in this directory cover every part of that equation, from a quick fix to a full replacement. Here is what each type of service involves, and when you are likely to need it.
Central AC repair covers everything from a tripped breaker and a refrigerant leak to a failing compressor or a blower motor that needs replacing. If your system is older than 12–15 years [verify & localize], or repairs keep adding up, a new installation — including ducted central systems and ductless mini-splits — can be the smarter long-term call. Companies listed here service AC units of every age and brand, so a technician visit starts with a proper diagnosis, not a sales pitch.
Furnaces, boilers, and space heaters keep your home livable through winter. Typical jobs: no-heat emergencies, noisy operation, pilot and ignition problems, carbon-monoxide safety checks, and full furnace replacement. Annual pre-winter maintenance is the cheapest insurance you can buy against a breakdown in freezing weather. If your heat stops working, prioritize companies that list emergency or same-day response in their profile.
Heat pumps heat and cool from the same efficient unit — air-source systems are the most common, with ground-source (geothermal) options for larger projects. Contractors in this category install, repair, and replace heat pumps, size them correctly for your home, and handle the ductwork modifications that a switch from a furnace often requires. If you are replacing an aging system, a heat pump conversion is worth having with two or three licensed pros before you decide.
Your ducts carry every degree of comfort to every room. Duct cleaning removes dust and debris that builds up over years; duct sealing stops the leaks that let conditioned air escape into attics and crawl spaces; and duct repair or replacement fixes crushed, disconnected, or rodent-damaged runs. If rooms in your house never quite reach the set temperature, airflow problems are often the culprit — worth checking before you blame the system itself.
Modern HVAC work goes beyond temperature. Air purifiers, whole-home filtration, humidifiers and dehumidifiers, ventilation and fresh-air systems, and UV treatments all change what you breathe. Companies offering indoor air quality services can test and improve air in homes with allergies, asthma, new paint or renovation dust, or simply poor circulation.
Offices, restaurants, retail spaces, and apartment buildings have very different needs than homes — rooftop units, package systems, and scheduled maintenance contracts that keep tenants comfortable and equipment warranties valid. The directory includes commercial HVAC contractors who can respond quickly when a business space loses heat or cooling, and who will quote preventative maintenance to avoid the midnight call-out later.
A spring tune-up before cooling season and a fall check-up before heating season catch small problems while they are still cheap to fix. Maintenance typically covers filter replacement, cleaning coils and burners, checking refrigerant charge, testing safety controls, and confirming airflow. Many companies publish maintenance plans in their profiles — compare what is included (and what an emergency visit costs) before you commit.
Systems break on weekends and holidays. Emergency-ready contractors keep after-hours teams for exactly the no-heat, no-cool, or gas-odor situations that can't wait until Monday. Check a company's profile for stated emergency availability and response policy before needing it — that is far easier than cold-calling on a Christmas morning.

Very satisfied with the work. Each worker was polite took the time to explain things to me and did a very good job. The area they worked in was extremely clean and they never rushed even when we were trying to get an app to work. Happy customer
A 6-week old heating system sold and installed by Princeton Air failed after a few weeks leaving us without heat in half the house for more than a week and counting. No sense of urgency or accountability or communication other than robo texts asking for 5-star reviews. Still waiting. Beware.
Brian was phenomenal!!! Very professional and extremely knowledgeable! He serviced my generator and replaced the battery. I would recommend him to everyone. Brian gets a 5 star!!!! The only issue I had was I was overcharged!
I had high hopes when I chose Princeton Air to install my new HVAC system but unfortunately the whole process has been very underwhelming. Princeton Air installed the system back at the end of June and by early August the condensing pipe started overflowing and the water saturated and damaged my floor. I had to hire a remediation company to remove the moisture and needed to replace my entire floor. Princeton Air told me that it was probably due to some blockage in my pipe, however, this was never an issue prior to the install and I have lived here for over 15 years. To me it seems like when they placed the AC unit down they compacted the soil, which blocked the outside drain of the condensing pipe because when one of their technicians removed the dirt surrounding the drain hole, all the water gushed out. I asked one of their managers why they didn’t check to make sure the water was flowing out properly during the install. He told me it was not part of the process. Princeton Air advised me to submit a claim through my insurance company for the damages and they would cover my deductible. Not sure why this wasn’t submitted through their insurance since it seems like they caused the issue. Regardless this incident occurred back in early August and I still have not received the funds to cover my deductible, which they told me that they would send right away. Additionally, it’s almost four months (16 weeks as opposed to the 6 weeks I was told) since the install that my local building department would contact me regarding the permit. I have called Princeton Air inquiring about it and they told me someone from their company will call me to discuss. No one has called me yet. Not sure what is the holdup in getting the permit and deductible that they promised me processed. Looks like I will be contacting the building department myself and notifying the NJ Division of Consumer Affairs and BBB. Didn’t want to go this route but I am left with no alternative choice since no one is responding to my calls. I highly urge you to use this company with an err side of caution because no consumer should have to go through all this. It’s been time consuming and stressful. UPDATE: Thank you for processing my refund. I had contacted Will on Monday (11/3) to obtain a status update on my permit but still have not received a call back. I contacted the building department and was told that they are in need of the application fee. Who can assist with this? Thanks.
I had maintenance service. Jorge was extremely professional and friendly. He didn't give up until he found reason for an issue and gave me recommendations. Some people will give up and take money and go, but Jorge took some time, analyzed all the options and explained me the issue very well. Thank you.
They were super helpful and efficient! We had an issue with our toilet and Jason did a great job fixing it. He came out on a Saturday and was in and out in quickly !!
