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.

Don’t like giving such a low rating to a local business but want others to be aware. Misdiagnosed a furnace issue and told me I needed a new furnace. Installed a new furnace which didn’t work. Then told me I needed a new EIM board which costs about $100. Now using another company to finish the job. When they sent me an invoice it was $1,000 over what they had quoted me for the new furnace install completed which they never did. Looks like a wrong diagnosis and up charging me for questioning things when it didn’t make any sense.
Lake Country Heating and Cooling were very punctual, fixed the problem with our furnace, were very neat and clean with the work they did, and were reasonably priced. This is not our first time using this company. They have put in a new air conditioning system in our home. I highly recommend this company for your heating and cooling needs.
Lake Country has serviced my HVAC since 2010. They provide the semi-annual service on my A/C and Heating and have alerted me to small problems before they become large costly issues. The techs they send out are always very courteous.
I have recommended Lake Country to neighbors and friends. The technicians are well trained, knowledgeable and friendly.. They respond quickly to my calls for service and I have never had a problem with their service or products. Their prices are very competitive. I like their discount club option which gives me good value on twice yearly service for furnace and air conditioner.
Lake Country Heating and Cooling came to my rescue December of 2022 when my geo thermal system stopped working. I was without heat and water. We explored different options and in the end, changed my house to conventional heating and cooling. Thankfully the team was able to install my units quickly and get everything back on track. The owner went out of his way to stay in contact with me. He made a stressful situation go as smooth as possible. I am beyond grateful. I even recommended this company to a friend who also had a good experience.
Cole serviced my air conditioning unit on 6/7/24 and was extremely pleasant and knowledgeable. Lake Country is always honest. They don't try to sell you anything that you don't need. Been going with them for years. Highly recommend.
