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.

Proper heating maintenance will ensure your heating systems’ longevity and keep the air quality clean. In addition to clearing out contaminants, periodic maintenance will help you determine your heater’s age and overall performance before you need to replace it.

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.

Your air filters should be cleaned and inspected every 3 months to ensure proper performance.
