Common signs that your air conditioner may need professional attention include:

- Unusual noises, such as grinding, squealing, or banging sounds.
- Strange odors coming from the vents.
- Water pooling around the indoor or outdoor unit.
- The system cycling on and off frequently (short cycling).

Professional AC Installation in University City
Whether you're building a new home in University City or installing an air conditioning system for the first time, choosing the right equipment and ensuring it's installed correctly is crucial for efficiency and performance. Our AC Installation services focus on providing systems that are perfectly sized for your home's square footage, layout, and insulation. Proper sizing is vital – a system that's too large will short cycle, wasting energy and failing to dehumidify effectively, while one that's too small won't be able to keep your home cool during peak demand.
We work with various types of air conditioning systems, including traditional central air conditioning systems. Our partnership with reputable manufacturers like Goodman, part of the Daikin family, allows us to offer high-quality, reliable systems known for their efficiency and durability. We handle every step of the installation process, from removing the old system if necessary, to placing and connecting the new unit, ensuring all components are correctly integrated for optimal performance and efficiency.
Seamless AC Replacement for University City Homes
Deciding whether to repair or replace an aging or frequently breaking down air conditioner is a common dilemma for homeowners. Our AC Replacement services in University City help you make an informed decision. While repairing a system might seem like the cheaper option in the short term, an older unit (typically over 10-15 years old) requiring frequent, expensive repairs is often a candidate for replacement.
A commonly discussed guideline, sometimes referred to as the "$5000 rule" (though the exact number can vary based on regional costs and inflation), suggests considering replacement if the cost of a single repair is roughly half or more of the cost of a new system, and the system is nearing the end of its expected lifespan. Beyond just repair costs, older systems are significantly less energy-efficient than modern units, leading to higher utility bills.
Replacing your old unit with a new, energy-efficient model offers numerous benefits:
- Lower energy consumption and reduced utility bills.
- Improved cooling performance and consistent comfort.
- Enhanced indoor air quality, especially when paired with compatible Indoor Air Quality products.
- Quieter operation.
- Increased home value.
- New system warranties providing peace of mind.
Our team can assess your current system, discuss your comfort needs and budget, and recommend the best replacement options available, ensuring a smooth transition to a new, efficient air conditioner.
The Importance of AC Maintenance
Regular maintenance is the cornerstone of a healthy and efficient air conditioning system. Just like a car needs regular tune-ups, your AC system requires professional cleaning and checks to perform optimally and avoid unexpected breakdowns. Our Maintenance Plan is designed to keep your system running smoothly year-round.
Annual AC maintenance visits, typically performed in the spring before the cooling season begins, involve a thorough inspection, cleaning, and tune-up of your system components. This includes checking refrigerant levels, cleaning coils, inspecting electrical connections, lubricating moving parts, and checking thermostat calibration.
The benefits of regular AC maintenance are substantial:
- Increased energy efficiency, lowering cooling costs.
- Extended system lifespan, delaying the need for costly replacement.
- Improved cooling performance and consistent indoor temperatures.
- Reduced risk of unexpected breakdowns during peak demand.
- Improved indoor air quality by ensuring clean coils and filters.
- Maintaining system warranties, as many require proof of annual professional maintenance.
Our proactive approach through routine tune-ups helps identify minor issues before they escalate into major problems, saving you time, money, and discomfort in the long run.

Frequently Asked Questions About Air Conditioning
Here are answers to some common questions we receive regarding air conditioning services in University City:
How much does AC replacement cost in University City?
The cost of AC replacement varies significantly based on the size of your home, the type of system chosen (e.g., single-stage, two-stage, variable-speed, heat pump), the SEER/SEER2 efficiency rating, and the complexity of the installation. Factors like ductwork modifications can also impact the price. We recommend getting a professional evaluation to receive an accurate estimate tailored to your specific needs and home.
When should I repair vs. replace my AC?
Several factors play into this decision: the age of your system (units over 10-15 years old are less efficient and more prone to issues), the frequency and cost of repairs, and your energy bills. If repair costs are mounting or a single repair is very expensive relative to the system's age and the cost of a new unit, replacement is often more cost-effective in the long run. An older, less efficient system will continue to cost more in energy bills even if repaired.
What are the most common AC problems?
Some of the most frequent issues include refrigerant leaks (leading to insufficient cooling), electrical control problems (affecting starting and stopping), sensor issues (impacting system cycling), drainage problems (causing water leaks), and issues with fan motors or compressors. Regular maintenance helps identify and prevent many of these common problems.
How often should I get AC maintenance?
It is generally recommended to have your air conditioning system professionally maintained once a year, ideally in the spring before the cooling season begins. This ensures the system is clean, efficient, and ready to handle the summer heat.
What temperature should I set my AC to in the summer?
The ideal temperature setting for comfort and efficiency varies by household preference. However, energy experts often recommend setting your thermostat to around 78°F (26°C) when you are home during the summer. For periods when you are away or sleeping, slightly higher temperatures can save energy. Using a programmable or smart thermostat can help manage temperatures effectively throughout the day.
