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.

What locals say about HVAC in Hacienda Heights

Lexus has fix multiple of my friends and family air conditioning problems. He is very honest and friendly. If it's a small problem he will only charge small problem price. He never try to upsale you for more parts or over charge for small problems or easy fix. Great pricing and friendly 👍

We hired Dr. Dio in 2024 right before one of the hottest summers, just as we were about to welcome our first child. During that time, we discovered asbestos and severely damaged AC ducts in our attic, so it was a stressful situation to say the least. After getting multiple quotes, Dr. Dio offered the best price by far. The timing couldn’t have been more intense — the day before the scheduled asbestos removal and AC installation, our baby was born. Thankfully, my mom was able to be there while the work was being done. Dr. Dio and his team exceeded expectations. They completed everything faster than promised, and by the time we came home from the hospital with our newborn, the entire system was up and running perfectly. It was over 106 degrees outside, and our home was cool and comfortable. It’s now March 2026, and the AC system is still working great. I’m genuinely grateful for the quality of work and professionalism. I continue to recommend Dr. Dio to friends whenever they need services.

I had an amazing experience with Dr. Dio Heating & Air Conditioning! Dio is incredibly experienced, fast, efficient, and knowledgeable, with reasonable prices. On top of that, he keeps everything clean and professional from start to finish. Even though he primarily services the L.A. County area, he went out of his way to come out to San Bernardino County for me, which I truly appreciate. Thanks to his excellent work, I'm now enjoying a perfectly cool and comfortable home. I'm beyond satisfied with the service and highly recommend Dr. Dio Heating & Air Conditioning to anyone in need of reliable HVAC work. You won't be disappointed!

I recently had all of my air ducts replaced by Dr. Dio and his crew, and I couldn’t be more impressed with the entire experience. From start to finish, they were punctual, professional, and incredibly respectful of my home. They took great care to cover all work areas and left everything spotless once the job was complete. What really sets Dr. Dio apart is his honesty and expertise. It’s clear he has many years of experience—he takes the time to thoroughly explain everything and never pressures you into unnecessary work. In fact, he’ll let you know if something can wait or doesn’t need to be fixed at all, which is refreshing compared to some larger companies that tend to upsell. Dr. Dio is not only highly skilled but also genuinely friendly and easy to work with. You can tell he has built his family-owned business on integrity, quality workmanship, and a true commitment to his customers. His pricing is very competitive, and he stands behind the work he does. I would absolutely recommend Dr. Dio to family, friends, neighbors—anyone in need of heating and air conditioning services. Thank you, Dr. Dio, and your entire crew for an outstanding job!
