Our Knightsen Air Conditioner
Maintenance Plan

Deep Cleaning & Inspection

We clean key components, including condenser coils, and clear the condensate drain. This improves efficiency, helps prevent water damage, and lets us identify early signs of wear or corrosion.
New Filter Installation

Proper filtration supports airflow, indoor air quality, and system protection. We’ll install a clean filter suited to your home and help you choose the right filter type and replacement schedule.
Thorough Refrigerant Check

Proper refrigerant levels are essential for efficient cooling. We check for low levels and leaks and, when needed, provide a clear estimate for recharging or repairs.
Comprehensive Ductwork Inspection

Duct leaks, blockages, or inadequate insulation can reduce efficiency and comfort. We inspect accessible ducts for gaps and airflow restrictions and recommend solutions to improve overall system performance.

Benefits of Routine AC Maintenance

Routine AC maintenance keeps your system efficient, reliable, and ready to deliver comfort every day.

Reduced Energy Costs

A clean, well-maintained AC system operates more efficiently, helping lower your monthly energy bills. Optimizing performance also prevents the system from working harder than necessary, providing greater energy savings over time.
Fewer Breakdowns & Repairs

Preventive maintenance identifies small problems before they turn into expensive repairs or unexpected breakdowns. Catching issues such as refrigerant leaks or worn components early helps keep your AC operating reliably.
Longer System Lifespan

A well-maintained air conditioner can last longer, helping delay the need for an expensive replacement. Regular maintenance keeps key components in good condition and helps prevent premature wear and tear.
Reliable Cooling Performance

Avoid hot spots and uneven cooling with an AC system operating at peak performance. Regular maintenance helps distribute cool air evenly throughout your home or business, improving overall comfort.

 Trustindex verifies that the original source of the review is Google. Smart Heating and Air replaced our aging HVAC system and helped us work through some challenging ductwork issues along the way. They were quick to respond and always showed up on time. They also shared photos and videos of our systems, which helped a lot when walking us through our options. Every person we’ve dealt with has been friendly, professional, and knowledgeable, and made us feel like family. Their pricing is fair, their warranty coverage is solid, and we haven’t found another contract that comes close to theirs. 100% we would trust our home with Smart Heating and Air the next time we have HVAC needs.

 Trustindex verifies that the original source of the review is Google. I found this company online when our AC suddenly stopped. We were fortunately able to get someone to stop by to take a look the same day. Sam was very kind and knowledgeable when finding the issue. When he told us that our old HVAC system served its time and needed a replacement, he came from a gentle approach to make sure he wasn’t forcing a sale on us. With his help and Mike’s approval, we were able to get an estimate that same day. Mike and Sam were very generous to give us some huge savings for a new HVAC system. I really appreciated Sam’s time to make sure we were all on the same page & answered all the questions we had. We were also able to get our new HVAC installed 2 days later.
Benny and his team were very respectful and worked very fast. They made sure to wear their slip on booties to wear indoors and they also cleaned up their work area very well before leaving. I’m very new to using an energy efficient HVAC system, so I really appreciate them explaining how it works and answering all my questions. I’m very excited with the new smart thermostat as well! Thank you so much and I will make sure to recommend you all to family and friends!
