Benefits of HVAC Maintenance

A furnace tune-up allows our team to detect issues with your system and prevent major repairs. In addition, it also allows us to optimize your furnace’s performance and ensure that it reduces any heating costs in the future. While we inspect your furnace, we also check your AC unit to ensure optimal performance. We test airflow, confirm communication with the thermostat, change out air filters, clean the internals, clear the drain line, verify the refrigerant charge and check for wear and tear. If your unit is experiencing any issues, we will provide you with effective and affordable solutions. 

What is an HVAC Tune-Up?

Charleston experiences a broad range of temperatures, so Max’s Fix-it 24/7 offers separate heating and cooling system tune-ups. Our goal is to service every aspect of your system to ensure peak efficiency and to inspect them before peak operating season. For your heater, this is right before winter, and for your AC system, anytime before June.

Airmax, locally owned and great customer service. They respond promptly and answered all my questions. Ryan the service tech, is a great team member and took the time to show me a couple of things with our AC system and throughly explained. I feel we made the right choice in having Airmax provide heating and air to our home 🏡.

Max's Fix-it 24/7 is phenomenal. I have a newer home (8 years) and I was told that both my units needed to be replaced. My neighbor recommended Max's Fix-it 24/7 Heating & Air and Rudy knows how to run a business. I had an issue that was caused by my maintenance man and because I was under the home warranty I was not charged for a visit. I promise no air conditioning is not a pleasant experience with the temperature this hot. My technician, Cody, was actually early, diagosed the issue in about two minutes and checked out everything giving me peace of mind as well. He was courteous, friendly and professional. I felt he gave me a thourough inspection as well. As a former Wendy's Franchisee I have dealt with the trades for over 30 years, please consider Max's Fix-it 24/7 Heating & Air for your HVAC needs.

No, it is highly advised that you contact a professional. Both heating and cooling systems involve electricity and can be quite dangerous for those with little knowledge about the repair process. Although it may be tempting, do not attempt repairs by yourself.

HVAC is a term that refers to heating, ventilation, and air conditioning. These appliances control temperature and humidity in a space to provide comfort and improve indoor air quality. 

Your HVAC systems should be serviced twice a year-before summer and before winter. If your system is older, it will require more frequent maintenance, closer to 3-4 times a year.

Don’t trust your HVAC system’s inner workings with just any contractor. For the best HVAC maintenance in or around the Charleston, SC, area, reach out to your reliable Max’s Fix-it 24/7 team today- we look forward to hearing from you!

On average, an AC conditioner will last between 10-15 years. However, if properly maintained and with regular check-ups, some can even last up to 30 years.
