Best Heating & Air Conditioning / HVAC In Fairfax

“I contacted Bluestar Air Mechanical for a second opinion after an appointment with Air One. I have a Carrier HVAC system, and the Air One technician recommended a complete system replacement, claiming the blower was bad, the furnace control board needed replacing, and that there were other issues. Since replacing the HVAC is a big investment, I wanted to get a second opinion. It was only after comparing the service from Bluestar that I realized Air One may have been pushing for a new system sale or lacked the expertise to properly diagnose and repair the actual problems. Isaac, the technician from Bluestar, spent about an hour thoroughly diagnosing and fixing the issues. He found burnt wiring in the furnace and discovered that the wrong capacitor had been incorrectly installed in the AC. Isaac replaced the burnt wiring in the furnace and the capacitor in the AC. After these repairs, my Carrier system was back up and running--without the need for a costly replacement. Bluestar, and Isaac in particular, demonstrated professionalism, expertise, and honesty. They focused on resolving the actual issues instead of pushing for an unnecessary system replacement. I highly recommend Bluestar for their reliable service and Isaac's thorough and knowledgeable work.“

“Professional, thorough, and they treat your house like their own. I’ve been with Ronan for 13 years for HVAC and plumbing and will never use anyone else!“

“We have used Breeze Master, Inc. for a variety of services to include HVAC system replacement (They made our system from 2000 last 3 extra years with tune ups till 2024), water heater replacement, smart thermostat install, drainage pipe replacement, vent cleaning, and general maintenance. Service technicians are certified, professional, and very knowledgeable. They never try to sell/upsell products and services. I asked about HVAC replacement and they told me that my system from 2000 should last a few more years and did a thorough tune-up. I was impressed with their honesty, transparency, and quality of service. We were provided an estimated quote before the commencement of the work and It didn’t change by a cent. I wouldn’t have any hesitation to recommend their services.“

“Comfort Defender LLC save the day and my pocketbook. Bought an older home with underwhelming HVAC and high utility bills. I went through several HVAC service providers for quotes to remedy my home's HVAC issues. Comfort Defenders LLC is by far above the rest. Sadaf is very pleasant, informative, knowledgeable, accommodating, and proactive with her customer service. Sadaf was very proactive following up on the service and flexible on payment terms. Their head consultant and foreman, David was timely, thorough, very informative, knowledgeable, and refreshingly direct and very honest. He did not try to upsell us on anything beyond what we needed. Infact, David seemed to take as much interest in being cost effective, and yet fully functional with our HVAC and water heater upgrades as if it was his own home which we really respect and appreciated. David and his crew work super-efficiently, neatly, tidy and thorough. Pleasantly surprised with both the experience, cost, and outcome. Our home is much more efficient now thanks to Comfort defenders LLC!“

“Nathan and Micah are two of the best in the business. They care about their clients and know their needs. They tailor their services to fit the owners' specifications. They are not pushy salesmen, but knowledgeable, honest and straightforward people. They educate you on their products and services and you decide! What a concept!“

“I recently experienced an issue with my AC unit at my Fairfax, Virginia home which required me to contact an AC repair company. I called a few companies, but landed on AA Rapid Plumming, Air Condition, and Heating for support.

It was a Sunday, my family had finally had enough of our not having cold air within our home, and we needed a company to come out and replace our AC fan motor. Within an hour of my speaking with Carlos at AA Rapid, Cesar was assigned to come out to my home to diagnose and resolve the issue.

Hail to Cesar! He was (and is) a true pro!!!! He was on time, thoughtful, answered all my questions, and even explained what I might need to consider in the future.

In truth, I chose them because they were available on a Sunday. But I received everything I asked for, needed, and more.

I would highly recommend using AA Rapid for your AC needs! Next time I have an AC or plumming issue - I know who I am calling.

Thank you, Carlos and Cesar!!!!“

“Incredible customer service, they will make you feel at home. Very reliable service - highly recommend!!“

“If you want to hire a professional team with fair prices and excellent work, Agcayazi, LLC is the one. No hidden fees, no overprices, or unexpected delays.

Without a doubt, we will use their service again and recommend Agcayazi, LLC to all our friends.Services: A/C system maintenance“

“The two technicians were thorough in inspecting my split system, communicated with the offsite boss, and alerted me about a potential problem that could require further service.“

“AVS was able to come on a Sunday to do an emergency repair with just a couple calls. Will definitely use them again“

“Rubio technicians are always polite, respectful and efficient. They carefully explain the details of their work and never try to upsell a service if it is not needed. I've used them for several years and am always satisfied.“

“Excellent work done by Peter, Young Kim, and Adrian of B&B during my recent Trane Air Conditioning system installation!“

“Wow! David exemplifies fairness and integrity, doing the right thing simply because it’s the right thing to do. Another company wanted over $1,000, overcharging on everything, lying about part prices, and refusing to provide a receipt when asked. They offered countless excuses.

Enter David. We had been without AC for two days in the heat. David educated me over the phone about various tricks some contractors use to exploit consumers who don’t know how to fix AC units. These consumers place their trust in the contractors' knowledge and experience, only to be taken advantage of. Using fear and misinformation, the other company tried to make a significant profit.

David came in, educated me, and genuinely cared about ensuring I was treated right. He fixed the problem in less than 15 minutes for a fraction of the cost the other company demanded. Very trustworthy and straightforward. I believe in karma and Google reviews, so I will ensure both companies receive the recognition they deserve in my reviews.“

“I had an excellent experience with Long's Corporation while replacing a hot water heater. Their booking process and communication was excellent. When I asked to change the brand of water heater they were very agreeable and promptly made the switch. The technician was efficient, tidy and knowledgeable. Highly recommend the company.“

“We have had five years of very good experience with our Waterfurnance unit and ground loop installed by North American GeoThermal. Occasionally our unit would go off line due to electrical storms so last year we had North American install the Intellistart component to forestall this from happening. This past year, the unit operated flawlessly. We travelled over Labor Day weekend - my wife noted that our home system is so much quieter and better than the hotel room units that were noisy, very drafty, and fluctuated widely between cold and hot.Service: A/C services“
