Why an AC Tune Up Is Important

The best way to keep your HVAC system running without breakdowns, is by keeping up with your maintenance and performing an AC Tune Up.  An AC Tune Up inspects all the components of your air conditioner and ensures it is working properly and efficiently. Prevent unexpected AC breakdowns and emergency AC repair by isolating potential problems before they surface.  A properly maintained AC unit can even use 20-30% less energy, saving you money each month, and paying for the maintenance itself!

The benefits of an AC Tune up are clear to see:

-Extend the Life of Your HVAC system

-Protect your system warranty

-Verify your system is cooling properly

-Assures your Freon charge is not low, and will keep you cooling all summer long

-Better your air flow & air quality

-Minimize and Prevent future breakdowns

-Improve the efficiency of your system and reduce utility costs

“I can’t speak more about how great Guardian is to work with. Their team is always friendly and I never feel like they are pushing services on me that I don’t need. Every question that I asked was answered and explained, so I can make my final decision. We’ve used a number of companies and finally found our forever home service company. ”

Casey G.

“When we woke up to no hot water, I was in a panic getting ready for my day. Guardian was our first call. The plumber that came out was so very thorough in explanation, gave me a few options and the information needed to make our decision. We ended up with a tankless water heater and I love having hot water on demand!”

Joe K.

“We were not thrilled to have to replace our 2 HVAC units because we knew the cost and time was going to be an inconvenience. After several quotes, we chose to go with Guardian. It was a big investment and I felt like I invested in the right people. The whole process was easy and they communicated well. Their pricing was very reasonable for the great service we received! ”

Adeline H.

“I never understood yearly maintenance on my home systems. When Guardian came out to my home to fix a problem, they explained the benefits to me and we chose to use them for our seasonal tune ups. They were right…I feel like we have less dust in the home and the air flow is better!”

Kathy R.

“If you’re looking for a company that cares about you and your home, Guardian is the right company. We’ve used a few others over the years and they always made us feel like we were just another dollar. Guardian has always taken the time with us in the home and are so easy to work with. Kindness, knowledge and respect goes a long way, and they provide it!”

Joe D.

“Incredible and prompt service, Extremely fair pricing in the market, very open with any and all details, very honest and sincere staff, excellent balance of professional and personal interaction. Honestly the best company I’ve worked with in my 20 years of home ownership across 4 states!”
