Reviews of local pros in Largo, Florida

Frontline Services ACHR are the air conditioning professionals you want, especially here in Pinellas coastal and Tampa Bay Florida area. They were strongly recommended by our neighbors and numerous general contractors as their HVAC professionals of choice. We followed their advice, contacted Frontline’s very friendly and helpful front office (btw, it is a family run business), and could not be happier that we did. Keng Yang, the owner, came to our house for a cost-free situation assessment, determined the problem, recommended a solution plan, and provided an estimate…with a very reasonable number. Keng is an affable, super experienced professional…and as we watched him on the job with his crew…it became clear that he is a natural leader and an AC wizard! The team is a close knit, highly coordinated trio of top notch HVAC experts, led right on-site by the company owner. You could tell that his employees loved their jobs, and their boss. Everyone was clean-cut, polite, respectful, savvy and hard working. They totally tidied up their work site. We contracted with them to install a new ductless mini-split air conditioner with two inside units; flush out the central ac outside condenser coils; increase height of the central ac outside condenser pad/platform.

I have used Frontline to install a complete new system at work (Air Handler and Compressor) as well as my personal residence (refrigerant leak & capacitor) . In both instances Frontline has been prompt, curious, fairly priced, and gets the job done right the first time. We are very happy with their services.

Update: 6/26/25: We had a situation that could have quickly become a major headache, but thanks to Keng and the Frontline team, everything was handled seamlessly. We initially called about a question with our office AC, but before that could even be resolved, we had an urgent situation at a client’s home. Without missing a beat, the Frontline crew stepped in and took care of both problems efficiently and professionally. Their responsiveness, expertise, and commitment to getting the job done right were outstanding. Highly recommend them, true professionals you can count on!

Only company to come in and give me a fair honest estimate. I had a company actually quote me with the exact same equipment brand/specs as Frontline and it was more than double. Company was very easy to work with no weird sales tactics, offered multiple financing options and got us going with a new HVAC system in less than 5 days of signed proposal. They showed up on time and kept a clean workspace. Just an overall great experience! Thanks so much!!

Keng was very knowledgeable and honest. We called for a maintenance visit on our 2009 unit which was running fine and cooling the house. He identified the potential issues that could break down soon with our older AC system and recommended waiting to have system replaced rather than try and repair things that will not increase the life or efficiency of our current unit. I will be using him to install our new AC in the future and referring him to everyone. So nice to finally have a company I can trust!

Keng has been very helpful when I needed my hvac replaced last year and now with replacing my house's ancient air ducts. Always helpful and pleasant to deal with.

Fast-friendly and knowledgeable. Dependable overall! Great personality and honest and did overcharge for a weekend call. They will be our new family ac service. We are extremely satisfied. We will use them for our business needs as well.

Keng is so responsive when an issue with our HVAC comes up and makes a point to try to fit you in especially when your air is completely out in August in Florida! We so appreciate Keng and Mia - they do a great job. Thank you.

Clay was amazing! Ken has been fabulous and I always request him but today wasn’t available. However, I was not disappointed; Clay was kind, thorough and equally as fantastic as Ken. HIGHLY recommend them both.

Excellent job and service! Keng was right on time and very professional. Have used Frontline before and they were great. Nice to know that we have a wonderful company on our side.

Frontline was able to do a major repair for a business at which I work. We had had bad luck using other A/C companies, who were unable to find the specific part needed to replace our unit (we waited months to hear back from other companies). After we contacted Frontline, it was just a couple of days before the entire unit was fixed. They also assisted same-day with adding freon to the unit so we could keep the building cool during business hours.

UPDATE 10/24 Paid $7000 1 year ago and second water leak has destroyed new paint job. He says out of warranty, Defective work.

UPDATE 8/24: Condensation leaking from Air Handler ruining hallway ceiling and wall. After 5 calls over 8 days and NO response from Keng, I had to hire someone else. Terrible.
Expensive, but excellent quality workmanship. Totally replaced 1 system and repaired the other at a 2 apartment home. He was polite & responsive.

We had a late day issue with our air exchanger and Frontline was recommended by people in our building. Frontline answered immediately and responded in kind. Keng took the time to explain the issue and the repair. He provided recommendations on the unit going forward & while he worked quickly, in ever felt he rushed the job. I would highly recommend this company. Well done.

What can I say, AC Frontline (Mr Keng) is the best AC company. They are always punctual and professional. Highly recommend them!

Keng is a super star and does professional work at an extremely fair price. I called at 3:20 and he had it fixed by 5:45 as my wife just had surgery and our house was 89 degrees but it is back to 72 now. Amen and bless you for all your quality work and professionalism as we truly appreciate you!

Requested a quote for replacing old worn out Heat Pump and Air Handler, price was very competitive to other quotes I had gotten and Keng explained his quote and equipment. I decided to go with Frontline and he scheduled with within a week because I was going to be out of town. He showed up on time and got the replacement done in a day. Very happy with the install and unit, Keng was very professional and I will definitely call him again for any HVAC needs.

Just had my AC fixed by Frontline Services in Largo. I called them this morning, I got a call back within 10 minutes. Appointment set for 3:00pm today. Keng arrived on time. I appreciate professionalism when I see it. He diagnosed the problem, installed a new motor under warranty, checked another issue with my duct work and repaired it. In all cases, he showed me clearly what he was doing and explained why! Price very reasonable. Thanks so much!
I cannot recommend him highly enough.

We have enjoyed working with Frontline Services for several years now. They consistently provide Prompt, Professional & Friendly A/C services. If you are in need of a quality company to service and/ or replace your AC system do yourself a favor, Call Keng at Frontline Services.

I know you will be very happy you called.

They are very professional and always deliver great results!

I’ve been a customer since I moved down to Florida 5 years ago. Frontline Service is very professional, they are always on time, and very reliable to take care of all your needs.
Our technician Clay is knowledgeable and courteous and a pleasure to work with.
I would recommend Frontline to anyone looking for a great HVAC service company.

Frontline Services was absolutely phenomenal! When my old HVAC unit went out during the hottest part of the year, it quickly became unbearable to live in the house. I reached out for quotes and got four different estimates—but Keng stood out right away. His professionalism, knowledge, and genuine care for my situation made my decision easy.

Even in the middle of his busiest season, Keng went above and beyond to fit me in for a Sunday installation so my family wouldn’t have to suffer through the heat any longer. He and his team installed a brand-new HVAC system with incredible attention to detail, and the difference was immediate.

From my first call to the final walkthrough of the new system, Keng delivered expertise, clear communication, and top-notch workmanship. The system runs beautifully, and the whole process was stress-free. Now we can live at home with comfort again.

Frontline services has been very helpful getting our AC system fixed. Though it was a process, they were very helpful and explained each step and made sure the work was done right. Keng and Clay were both very friendly and I felt comfortable having them work in my home. Scheduling was easy and their automated texts alerted you when they were on their way. They were referred to me by my father who would write a similar review if he knew how to : )

Wonderful people to work with.
