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.

Ernie and George were awesome to deal with and worked hard to get us on the schedule to replace our AC unit even with the HVAC buiness being straight out. Promoted, courteous and professional!!
Our AC turned off yesterday and even on a Sunday they answered our call and scheduled us an appointment for the following day! They service central AC, which is rare. Super friendly, very insightful, and reasonable pricing! We'll definitely be using them again in the future! Choose Cal's for you air conditioning needs!
Ernie was great! Found him on Angie’s list and couldn’t have been happier. I received 4 quotes for a ductless split system on my home with an air handler for the second floor and an in-law suite as well. Ernie was extremely competitive with his pricing. Ernie was on time, extremely clean and meticulous. He even vacuumed the house after installing. He took the time to explain in detail how everything worked and the most efficient way for everything to work as well. I Highly recommend Ernie, you’ll be happy you hired him.
Cal is just amazing and definitely one of a kind business as in service quality and professionalism. I was first introduced to cals back in 2004 when I bought my home in Derry. He has never failed me at anything! From installation of my furnace, not one ac units but two over the years. He continues to reach out with a call to make sure I don't have any further questions after his work. He is polite, kind and straight shooter as in professionalism and quality of his work and clean up afterwards. He has always quickly responded to any and all service questions and conducted repairs immediately. Not many like him and his crew left in the world. Just amazing I highly recommend him and his services and WILL ALWAYS use his company.
Just had a great experience with Ernie and George. They just replaced our furnace because it was on it's last legs. He was able to get to us right away because my Mom was having a problem with the cold. Was very quick replacing it and was great with the price especially when everyone else we called were much higher on their price with a much longer time line to replace it with. Couldn't have gone any smoother. I would highly recommend Ernie and Cal's they're very good and caring and tells with his quality of work.
Highly recommend without reservation. Cal’s is a top notch, reliable business with expert level techs. I had the pleasure of the owner (Ernie) servicing our equipment (both AC and heat). He was patient, diagnosed and trouble shot the problem, - all while being patient and explaining the technical issues in layman’s terms. The prices are very fair and reasonable, and are conveyed in quick turn without surprises. We recently had our ACs go out one hour before a house full of guests arrived. I texted Ernie in a panic and he was at my house in 30 minutes and fixed the issue within 30 minutes. Grateful, doesn’t even come close to explaining it. This type of customer service and high technical skill is rare nowadays. This business is exceptional.
