Reviews of local pros in Largo, Florida

Keng and Clay are awesome.... I just love my new central air..They explained everything to me. and did things in a timely manner both men have compassion I had a problem and they took the time out to talk to me. I really don't know of anybody else that would've done that. I recommended this company to one of my friends and she feels the same. I'm so thankful that I found them. They're prices where the best. And that's truly doesn't hurt. Sandra

Update: I have continued to use their service because of their endless reliability! Thanks again!

I love working with ACHR. They have always been there for me, on time, efficient, honest, high-quality work without the huge price tag. Thank you all! Keng & Clay have been great to work with through the years.

They were on time for the service call. The tech was very polite and explained things to me so that a non-tech person could understand!

We have used Frontline Services since we moved to Florida 5 yrs ago. Had a routine check on A/C unit and decided to have a need one installed due to our unit being 20 yrs old. The service is excellent and the employees are friendly. They keep you up to date on when they are on their way. Keep you informed on what they need to do. Would highly recommend their service.

Hands down the coolest HVAC installers.

They are quick, prompt, and professional. Installed new system for a 2 story house that works great now.

We recently purchased a new home and after having issues with the new house's HVAC they were able to accurately assess the issue and save us money on a resolution.

Provides constants updates and multiple options.

Asks for payment after job is done.

Keng Yang at frontline is amazing. Company is great and easy to work with.

Keng was outstanding!! Very honest, very trustworthy!! Knows his stuff! He will not rip you off like other companies out there. He has earned my trust, Keng will be the only one that will work on my HVAC system from now on.

Frontline was extremely attentive and helpful when my AC unit needed some help. I was recommended to use Kane & Kane was absolutely fantastic. He knew exactly what needed to be done and got my AC unit fixed and running within a couple hours. If I ever have any trouble (fingers crossed I don’t) with my AC ever again I will immediately call Frontline again. Couldn’t recommend them enough. Affordable too.

Great company to work with. Very quick to come out. Will definitely use again

Excellent workmanship, professionalism, timeliness, and cleaned up afterwards. Checked to make sure everything was working, not just the area they worked on. This has been an ongoing situation since 2018 and trying with resolve this issue through 3 companies that cost me 6x the amount it should have cost. It left me with PTSD and fear of contacting service people in all industries. Keng has resolved the issue and lifted a massive burden off of my shoulders. I highly recommend Frontline Services.

6/16/25: Keng has been servicing and keeping our 20 year old system running for MANY years and it was finally time to replace it. Keng knew exactly what was going to be best for our home, explained in detail each recommendation and gave us three different price points to choose from.

We had our system installed today and the installation went great. The installers are freaking ROCK STARS; they showed up early and worked non-stop for 9 hours. They cleaned up the mess from the install and made sure the system worked as it should before leaving.

Frontline Services is the best HVAC company in Pinellas County and you should not hesitate to call them. Prices are the best in the business, techs are great and Keng knows what he is doing!!

2/10/23: Quick, honest, reliable, affordable... Do yourself a favor and call Keng first; I guarantee that you will never call another a/c company again.
*****************************************************
5/19/21: No doubt about it- Keng is the absolute best a/c tech around; no one else will ever service my HVAC system! He knows what he is doing and he gets it done right the first time! It doesn't matter when I call him- he comes out as quick as he can and gets us up and running the same day. Do yourself a favor- call Keng for all your HVAC needs and save yourself the hassle of dealing with rude, unreliable, dishonest service techs.

Great service again. AC stopped working the night before and contacted Frontline this morning and they fit me in. Technician Clay assessed the issue and made the repair. I highly recommend Frontline for HVAC!!

Fantastic service! I am set for summer now with my new mini splits! (and winter when it arrives as well!) Mr. Yang and his assistant worked tirelessly to set me up beautifully! I would recommend them to anyone interested in upgrading their heating and cooling systems!

Excellent service. Very efficient and punctual. Keng is very knowledgeable and offers expert advise.

My experience with Keng & his team was fantastic. They replaced our AC (which was particularly challenging due to home structure). Frontline's price was MUCH more affordable than two others we considered, and they completed the job efficiently and without any problems. They were on time every day and easy to communicate with. Zero bad things to say about Keng or Frontline!

At the beginning of December, when a cold front came through, we turned on our heat only to find it was blowing cold air. We reached out to Frontline Services ACHR, and within a day or two, a technician named Clay came out to assess the issue. He quickly identified a wiring problem and was very transparent about the repair costs. In about an hour, he had our unit working perfectly, blowing warm air again.

Clay took the time to answer all my questions, explaining what he was doing and why. After completing the repair, I asked him to inspect our entire system. Before proceeding, he provided a clear and fair price for the inspection, which I appreciated since it was an add-on to my original request. The inspection went smoothly, and our system passed with no further issues.

It’s been about three weeks since Frontline Services ACHR came out, and our system has been running perfectly ever since. If we ever have another concern with our HVAC system, we’ll definitely call them again!

Keng is the best. After multiple projects we enthusiastically recommend Keng Yang and Frontline. Excellent work and men of integrity. .

Keng was highly recommended and I was super excited when he agreed to squeeze me in at 8 PM the same day. However, he charged me a $150 service call to quote me $6000 to remove and replace all my duct work because he says it’s under sized (which it may be) but worked fine for all these years. He refused to even address the mechanical problem until I spent the $6000. AND told me he couldn’t even get to it for a month! I finally got the actual needed repair done by another company for $400 and everything is working great! Because of this, I am sorry I cannot recommend Frontline Services ACHR.

Clay McClure was very polite & professional. Extremely satisfied with svc performed. Definitely a new Frontline customer.
Thx! Bill E. Sladewski

Frontline services changed out my entire HVAC unit. The Team works very well together. Keng took time to go over the installed High Tech Smart Thermostat. Thanks for your expertise Keng !!
