AIR MAX HVACR LLC We take great pride in our experience, expertise, quality, and customer service that we provide to meet our consumer's needs. In order to understand expectations of our customers, we take great care to work and communicate with everyone in a professional manner. Our reputation is based on service, safety, and quality, regardless of how large or small the job.

"I have used this company twice. I first gave them a call over the summer for an emergency central AC issue. They were able to quickly come out, ID the problem and fix it the same day for a very reasonable price. They did so well that I called them again a couple of weeks ago when I tried to flick my furnace on for the first time and nothing happened. When it rains, it pours, right? Once again, Air Max was able to quickly respond and found a simple sensor problem and the whole visit took less than an hour and cost me under $100. I feel like I would have been out at least a grand calling another company. I TRUST these guys!"

"Henry was professional and thorough. He went out his was to see that our heat was restored on the coldest day of the year. You can spend a significant amount of money dealing with the big HVAC advertisers in our market but why pay for their ads when you really want competent service? This company provided me everything I expected in a repair."

Air conditioning services FAQs

You should schedule professional maintenance for your mini-split AC once a year, ideally before the cooling season starts. This keeps your system running efficiently and helps prevent costly repairs. Don't forget to replace or clean the filters every three months—more often if you have pets or a lot of dust. Regular upkeep extends the life of your system and ensures optimal performance.

Mini-split ACs are versatile and work well in most homes. They're efficient in small and medium-sized homes and can even outperform central AC systems in larger or multi-level homes. Many homeowners install mini-splits to supplement their existing central AC, especially in additions or remodeled areas where extending ductwork isn't practical.

Mini-split ACs are quiet, producing noise levels between 20 and 35 decibels—about the same as a soft whisper. This means you'll enjoy a quiet and comfortable home environment. Central AC systems can be louder, operating between 50 and 60 decibels. The minimal sound from mini-split units helps enhance relaxation in your home.

Choosing the right mini-split system size is key for effective cooling and heating. Assess your home's square footage, number of floors, window placement, and ceiling height to calculate the required BTUs. HVAC professionals use these factors along with the guideline of 12,000 BTUs per 500 to 600 square feet to determine the optimal size. Proper sizing maximizes efficiency and prevents energy waste.

The SEER rating shows how energy-efficient a mini-split AC system is. A higher SEER rating means better energy performance, significantly lowering your energy bills and increasing long-term savings. When choosing a model, look for higher SEER ratings to maximize efficiency and cost-effectiveness. Greater energy efficiency can also extend the system's lifespan by reducing strain on its components.
