Some Words From 
Our Customers

I was so pleased with the installation of my new A/C and furnace that I have scheduled the installation of a new water heater with Guardian as well. Fantastic service, skilled and knowledgeable technicians, competitive prices on quality systems.

Had a wonderful first experience using Guardian for our electrical needs! It’s nice to know there are still good, honest companies out there that are committed to their customer’s needs without charging a fortune. Will most definitely be using again!

When my air conditioner stopped working, I found Guardian online and was thrilled with their service! My old unit was on it's last leg and the technician gave me options. He showed me what needed to be repaired, walking me through the problems. The technician gave me the repair costs and also provided me with some options for replacing my HVAC system. It made sense for me to replace my unit and that process went so smoothly. No pushy sales. Great installation. No question this is an honest company that provides the best customer service I have had from any HVAC company. I will be recommending them every chance I get.

Experience

Experience

What is the experience level of the owner and the employees? There is something to be said for a business that has the expertise and knowledge to provide you with the right solutions. A company that is licensed, bonded and insured is important in protecting you and your home. We see it every day... the "handyman special". Often times, we are called to fix improperly repaired and poorly installed equipment. While competitive pricing is important, be weary of companies that offer a low low price. Guardian offers over 25 years of experience and a team that is trained weekly. We only hire experienced professionals that have been in the industry for years to best assist you.

Reliability is Important 

Reliability is Important 

Is this company going to be there for you when you need them most? Make sure that the company you choose considers you a priority. Don't fall into the nightmare situation of being unable to reach your company when you need them most. How do you know if this is a possibility? Just ask! How many technicians does the company have on staff? How many installation teams? If a company only has a few employees, this may cause you to have extended wait times. Bigger is not always better either. A company may have 200 employees but often that too comes with a cost. Guardian is unlike many of the companies in Atlanta. As a locally owned and operated company, we put a priority on our existing customer base and relationships. Read our reviews! If a problem arises with your heating and air system, we prioritize you. Period. We are fully staffed to handle your call!

Company Guarantees & Reviews

Company Guarantees & Reviews

At Guardian, your satisfaction is always guaranteed – 100%! That means we do all we can to make sure you are happy with our service and your experience. We want lifetime customers from each interaction, not just “done and run” once our competitors collect your money. The quality of reviews makes a difference. Sometimes quantity is great, but remember the best reviews are the ones that provide you with a good explanation of what to expect. This goes for good and bad reviews. While every company may be faced with disgruntled customers, company response is important. If you notice a trend in negative reviews you may find yourself in that position as well. Always do your research- it can save you time and money! Guardian is 5 star rated and it shows! While we are not perfect, we are perfect at responding to our customers' needs.
