What to know about HVAC

Four Rules How to Choose the Right Contractor

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.

Start with ratings and recent reviews

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.

Compare services, service area, and response time

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.

Get at least two written estimates

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.

Verify credentials for your trade

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.

Questions to ask before booking

  • How long have you been working in my area, and are you licensed and insured for this job?
  • Will I receive a written, itemized estimate before any work starts?
  • Do you guarantee parts and labor, and for how long?
  • How is emergency or after-hours service charged?
  • How long will the job take, and who do I contact during the work?
  • Can you share a reference from a similar job in the last six months?

Red flags to walk away from

  • Vague pricing that changes once work begins, or pressure to sign today.
  • Refusal to put the estimate in writing.
  • A "free" check-up that always concludes with a full-system replacement.
  • Requests for full payment upfront before any work is performed.

Your One-Stop Hub for HVAC Services Across the Country

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.

Services You Can Find on Gigo

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.

Air Conditioning Repair & Installation

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.

Heating & Furnace Services

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 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.

Ductwork & Ventilation

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.

Indoor Air Quality

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.

Commercial & Multi-Unit HVAC

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.

Maintenance & Seasonal Tune-Ups

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.

24/7 Emergency Service

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.

    Wow! These guys were great right from the beginning. They got back to me in a club with in a timely manner. They were polite and professional and answered all of my silly questions. They arrived 10 minutes early And we're super considerate. We moved in the day before they arrived to replace our old leaky oil tank with a brand new one. They insisted on helping us find an outdoor outlet so they wouldn't let cold air into our house. They were in and out in a couple hours and did a great clean job. No mess! I am honestly so surprised that they don't have more of use but it doesn't surprise me that the ones they do help her 5 star! We plan and recommending them to anyone we know who needs an oil tank.

    Oil tanks of NE saved us from a cold end of winter! My oil company decided not to tell me my tank was wearing down until it was "undeliverable" so I was stuck at the beginning of February with no heat whatsoever. After calling around several places and receiving no response, Oil Tanks immediately picked up despite being out of state at the time. They attempted to squeeze us in for a whole new tank and pad barely two days later. Unfortunately snow storms delayed them for another week(totally understandable! they called ahead each time to reschedule) but today they were here promptly at 8am and I had a new tank and a fresh slab installed despite the snow and frozen ground. Barely took 2 hours! Thanks to them I am back with heat and for a fair price. Completely recommend this company.

    When I re-sided my house, the old oil (kerosene) tank was nearly touching the house siding, making removal and replacement of siding impossible without moving the tank, which was nearly 30 years old. I called Oil Tank Services of New England and received a quote for removal and installation of a new tank. I specified additionally that 1) I would like the tank filter replaced and 2) I wanted the new tank and concrete pad placed ~12 inches out from the house siding so any future work could be completed without disturbing the oil tank. I was told this could be done, but removal of the old tank and installation of the new one would be done on two separate days so I could complete the siding installation first. This was fine, as it meant I could complete work on that side of the house unimpeded by an oil tank. The initial removal of the tank went well - the two gentlemen showed up on time and were careful and efficient. I called when the siding was completed. Unfortunately, I had to work on the day when the installation of the new tank was scheduled. When I arrived home, I found that the new tank was placed ~1 inch away from the new siding - almost touching in one corner. In addition, there was no in-line filter placed downstream from the tank - just the line running into the house and then to the heater. I called the next day and explained the situation. I was told they could come back and move the tank / pad and add a filter. I was given a date a few weeks later when these changes could be made. The appointment date came and went and nobody showed up. I called multiple times and left multiple messages asking for a return call, which I did not receive. Eventually, I called from my work phone and received an answer. I explained the situation once again and was told (including expletives) that they "did what they were going to do" and they were not coming back for any reason. I was able to add an in-line filter the following summer myself after the filter in the heater plugged several times during the winter, causing the heater to starve from lack of fuel. This was frustrating but not the end of the world. What was most frustrating was the lack of professionalism I experienced. I hesitate to give a one star review given that the tank and concrete pad were of good quality and the price I was charged was reasonable and consistent with quotes I received from other companies. However, given that only part of the job I specified was performed and the way I was treated when I called to have the rest of the job completed makes me hesitate to recommend this company. You may do well if you need a simple tank replacement but if you need anything beyond that, I would look elsewhere.

    Mike and Eric rock! The price was right, and their experience shows. They did two new tanks transferred fuel and took the old ones with them. Cleaned up after themselves, All in about 5 hours! I highly recommend them.

    Just had three old tanks removed and two larger ones installed. Not an easy job to remove the old ones but Eric and Mike found a way and did a perfect job. Oil Tank Services of New England is easy to do business with, prompt and reasonable. Strongly recommend them. Scott
