Some Words From
Our Customers

Josh and his electricians did a tremendous job for us in January February and March for a family room, kitchen dining room remodel and were always neat and clean. I have just had them return to replace some fixtures on our master bath and again they were clean and neat. We will call guardian 1st and we have needs in the future for electrical upgrades or service work

- Gary Huggins

We had a leak in our foundation. Adam was quick to come out the day that I called for an estimate and had Rob & Javi come out the very next day to start the job! Rob & Javi did a stellar job repiping our entire house. Both work efficiently and quickly to get the job done. Both were very friendly and answered any questions/concerns we had! Thank you all for the fast turnaround and stellar work! Both myself and husband are so appreciative!

- Charlene Boyer

My mom recently had Adam come to my mom’s condo. She wanted a water softener installed. He was polite and knowledgeable. My mom had the installation done and Justin and Tai were excellent in their workmanship. They were neat and gave us instructions for usage. Having a small area to work around, Adam and the guys were able to make the unit work in tight quarters. My mom is thrilled.

- Karen M

I needed to replace my entire AC / HVAC system because my old system had several problems and not cooling very well. They were out quickly and had it professionally installed in about 1/2 day. The techs were very friendly, hard working, and cared about my house while working. The price was much less than others (had some energy rebates) and my unit now has a 10 year warranty that can be transferred to another owner. I am impressed with the companies communication and shared knowledge that I got all along the process from researching to after care maintenance.

- Mark Esslinger

Brand new York A/C install after my old unit quit. There was a manufacturer defect discovered when installed. Gaurdian did not cut corners, they replaced with an entirely new unit to fix the problem. Both York and Gaurdian stood behind the product and workmanship with 0 hassle. Justin did a great job installing new unit and going over its operation. Great pricing, great product, great people. 10 out of 10 Highly Recommend! Thanks Again!

- Phil G

I want to share our experience with Guardian Home Services in Oldsmar. They were recommended to me by a realtor friend. They were outstanding. I reached out to Tammi (big boss in charge of everything) when our AC went out. We had a bid from our regular heating and air company for a new system and we were floored at the high price. No discussion of options or various price points. Tammi was super helpful, listened to my needs and sent Justin out to propose a few systems. He was patient and explained everything and answered all my questions. My husband and I chose one and sent Javier and his assistant Zac to do the install. Zac and Javier could not have been nicer! I would recommend that you call Tammi with any of your AC needs. They made us a priority and helped us when we needed it. Great price. Great company.

- Janice Swenarton

I recently had my AC replaced by the team from Guardian Home Services, and I couldn’t be more pleased with the entire process! From the moment Tammie referred us to them, everything went smoothly. Jay, who came to provide the details, was incredibly knowledgeable and took the time to explain everything I needed to know about the new system. His expertise really gave me confidence in the service. The installation team, Javier and Zac, were absolutely fantastic. Despite the hot weather, they worked tirelessly and efficiently to get the new AC installed. I gave them props for their dedication, and they truly earned it! I’m so grateful for their hard work and professionalism throughout the whole process. If you're looking for reliable and friendly AC service, I highly recommend Guardian Home Services. Huge thanks to the entire team
