Does Your AC Need to Be Replaced?
Typically, a central air conditioning system lasts 12 to 15 years. If you notice that your energy bills are higher and your AC is not keeping your home as cool as it used to, it may be time for a new system.
Our team understands that choosing the right air conditioning unit can be overwhelming given the diverse options and considerations to keep in mind. We factor in your home's size, existing ductwork, and your specific cooling requirements to guide you in making an informed decision. Our consultation process is designed to educate you on the latest energy-efficient units that not only improve your home's comfort but also align with eco-friendly standards.
As convenient as online shopping is, installing a new air conditioning unit is much more involved than a point-and-click experience. There is a lot that goes into choosing the system that is right for your home. For example, did you know that getting an AC that is the appropriate size for your home is critical to the efficiency and longevity of your system? Our highly trained cooling experts have extensive experience helping customers choose the unit that is right for their space.
Not only do you need to make sure that you choose the right system, but you also need to ensure it is installed correctly. Improper installation is another primary cause of inefficient operation and decreased system lifespan. When you rely on our skilled team of technicians, we’ll make sure your new system is properly installed and set up to run at peak performance for years to come.
Maintaining & Repairing Your AC
To get the most out of your air conditioning system, you should schedule a routine maintenance appointment. We recommend that you have our professionals inspect and tune your AC at least once a year. Not only will this keep your system running in optimal condition, but it also allows us to spot and correct minor issues before they become big-time problems that cost an arm and a leg to fix.
Our maintenance plans are designed with flexibility and convenience in mind, offering customizable schedules that fit your lifestyle. We use advanced diagnostic tools to ensure that each component of your AC system is functioning correctly, helping to extend the life of your investment. During each visit, our technicians provide you with documented reports and insights on your system's performance, empowering you with knowledge about its current condition.
Speaking of fixing, if you notice anything strange going on with your AC – like funny noises, strange smells, odd operating sequences, or warm air – you should call us for repair immediately. The sooner we resolve your problem, the sooner you will be back to living comfortably, and the more likely you will avoid excessive damage or even total breakdown. We offer 24/7 emergency repair services if you have an urgent matter!
Ductless Mini Split Services in St. Louis
At Martin-Jetco Heating and Air Conditioning, we also offer ductless mini-split services. A ductless mini-split is an efficient and cost-effective way to add cooling to specific rooms of your home. This type of system consists of one or more indoor wall-mounted units that are connected to an outdoor compressor. And as the name suggests, they don’t require ductwork!
Ductless systems are perfect for regulating temperatures in rooms that are difficult to reach with traditional ductwork. They offer zone control so that each room can maintain a different temperature, ideal for family members with varying climate preferences. By switching to a ductless setup, you can achieve a significant reduction in energy consumption, which reflects positively on your utility bills.
You may want to install a ductless mini-split if:
- You value energy efficiency
- You do not have ductwork in your home
- You desire to decrease your cooling bills
- You wish to improve your indoor air quality
- You are building onto your home
If you are already benefiting from one of these highly efficient cooling systems, and you start experiencing issues with it, we are available to provide a fast and speedy repair.
FAQ About Air Conditioning Services in St. Louis
How Do I Know When My AC System Needs Maintenance?
Most people in St. Louis realize their AC system needs maintenance when they observe performance issues such as decreased cooling efficiency, unusual noises, or increased electricity bills. A routine maintenance schedule is crucial even if your system appears to function correctly. Scheduling an annual check-up can save you from unexpected breakdowns during the hotter months. Our team conducts comprehensive inspections, ensuring that all critical components are performing optimally. By taking an anticipatory approach, we aim to extend the lifespan of your unit and maintain a cozy, comfortable living environment year-round.
What Is the Most Energy Efficient AC System?
When considering an energy-efficient AC system, it's important to look at both SEER (Seasonal Energy Efficiency Ratio) and EER (Energy Efficiency Ratio) ratings. High-efficiency units with variable-speed compressors and smart system integration are becoming the norm. These systems offer the advantage of adaptive cooling, where the speed of the compressor adjusts based on the current demand, reducing energy waste. At Martin-Jetco Heating and Air Conditioning, we offer a range of energy-efficient solutions tailored to your specific needs, helping you save on utility bills while maintaining superior indoor comfort.
Why Should I Consider a Ductless System?
Ductless systems provide a unique solution to cooling needs in St. Louis homes, particularly older properties without existing ductwork. The ease of installation, coupled with their ability to offer personalized zoning, makes them an excellent choice for those looking to improve energy efficiency without extensive renovations. They offer enhanced air filtration, which can improve indoor air quality significantly. This system type allows homeowners to achieve highly targeted, room-specific comfort levels, making them ideal for spatially diverse environments and properties with unique architectural challenges.
What Are the Common Signs My AC Needs Repair?
An AC unit that requires repair commonly exhibits symptoms such as frequent cycling, unusual noise, or uneven cooling throughout the home. Warm air coming through the vents, moisture around the unit, or higher-than-usual utility bills can also indicate that a repair is needed. Our technicians recommend contacting us at the first sign of trouble. Addressing these issues promptly can prevent more extensive damage and ensure your home remains comfortable during those warm St. Louis summers.
What Benefits Do I Gain from Regular Maintenance?
Regular maintenance of your AC system is a proactive strategy for enhancing its performance and extending its operational life. Benefits include improved energy efficiency, lower utility bills, and a reduced risk of unexpected system failures. Regular check-ups enable us to identify worn-out components before they cause broader system issues. They also ensure your AC is tuned to cope with Missouri's unique climate challenges, delivering optimal comfort while being mindful of your energy consumption. Our maintenance packages are tailored for flexibility, allowing effortless integration into your busy schedules.
Whatever your AC needs, contact our St. Louis air conditioning experts today at (636) 205-1631 for a high-quality solution that lasts.

We love Martin-Jetco! We had an issue with needing a new heat pump and AC only a year and a half after buying our house. and they walked through all our options and had a new system ready to install in matter of days! (In the middle of summer last year!) Then whenever we have user issues (In our case forgetting to change our filter promptly, which had minor repercussions!) they are always willing and able to help as soon as possible! Thanks Martin-Jetco- Laura G.
for being honest and believing in the golden rule! -
AC went out and it was a bit of a puzzle as to why. Shout out to tech John DeClue who came out at 4:00 on a Friday and figured it out. Was a bad wire causing a short. Looked like a maybe a bad compressor, but he worked the problem and found the solution that saved me a lot of money! Martin-Jetco is a great company.- Ken M.
