Hiring an HVAC professional is a decision about your budget, your comfort, and sometimes your safety — so it deserves more than an impulse phone call. This is the short version of how we'd approach it, and the exact criteria embedded in every GigoPro profile.
Ratings tell you the average; recent reviews tell you the truth about right now. Read the last handful of reviews for a company, not just the stars. A contractor who fixes the reported problem, explains what was done, and leaves the site clean is the one you can trust with a multi-thousand-dollar decision.
Confirm the company actually performs your specific job — a residential AC repair shop is not automatically a commercial rooftop specialist, and vice versa. Check that your address is inside its service area, and look for stated response times if your situation is urgent.
Reputable pros will inspect, then give a written, itemized estimate — clearly stating labor, parts, and any permit costs. Price differences between honest quotes reflect equipment brands, warranty terms, and installation quality, so never choose on the bottom line alone. Ask what each quote includes and what it excludes.
Licensing and insurance requirements differ from state to state and shift over time. In regulated jurisdictions, ask for the company's license number and proof of insurance before work begins — never after. Professional companies expect these questions and answer them without hesitation.
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 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 100 000 start their 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.
GigoPro lists providers in 10171 cities across all 50 states. Each city page shows local air conditioning, heating, and ventilation companies with their ratings, recent reviews, service areas, and contact details — so you see exactly who operates near you before you call.

Eric was a real lifesaver for my family. We had just moved into a rental home and our new dryer was not working right. After a full dryer vent and chimney-related inspection, he found the vent line was about 95 percent blocked, with heavy lint buildup and even a bird nest inside. The property management side had not been much help, but Best Chimney Sweep Company got everything cleaned out and working safely again. He got us taken care of quickly, explained the fire risk clearly, and shared helpful safety tips for our family in case of an emergency. I am very thankful, because if the vent cleaning had not been done, it could have turned into a serious house fire later on. It is rare to find someone who is this thorough, honest, and caring. I would gladly recommend him to anyone needing chimney sweep or dryer vent cleaning service.
Fantastic experience. As a first-time homeowner, I was new to fireplace and chimney care, and our gas fireplace was not working right. I spoke with Eric on the phone, and he was very helpful and kind. He clearly explained the chimney and fireplace service steps, what needed to be checked, and what the repair process would likely involve. Everything was explained in simple terms, which made me feel much more comfortable. They were able to schedule a chimney and fireplace inspection quickly, and Johnathan came out to service the unit. He was professional, efficient, and took the time to make sure the fireplace was working safely and properly before he left. The pricing was fair and reasonable, and the service was even better than expected. I really appreciated the honest communication, fast response, and quality chimney sweep and fireplace service. I would gladly recommend them to neighbors, family, and friends.
Quick and effective chimney repair.
Thorough and reliable chimney cleaning.
I’m thrilled with the results of their work.
The installation was seamless and hassle-free
