We handle every step, from removing your old unit to installing the new one and ensuring it's calibrated correctly for peak efficiency. We also explain how to operate your new system and go over the warranty details, including the excellent limited lifetime warranties offered on many Goodman compressors and heat exchangers.
Repair vs. Replace Your HVAC System
A common dilemma for homeowners is deciding whether to repair a malfunctioning HVAC system or invest in a complete HVAC replacement. This decision often involves weighing immediate costs against long-term savings and reliability. Here are factors we help Ballwin residents consider:
- System Age: HVAC systems typically last 10-15 years for air conditioners and heat pumps, and 15-20 years for furnaces. If your system is nearing or past its expected lifespan, replacement often makes more sense than costly repairs.
- Frequency of Repairs: If your system requires frequent repairs, the cumulative cost can quickly add up. Investing in a new, reliable system can save you money and hassle in the long run.
- Cost of Repair vs. Replacement: A commonly cited guideline is the "$5000 Rule." If the cost of a single repair multiplied by the age of your system exceeds $5000, it might be more economical to replace the unit. For example, a $500 repair on a 12-year-old unit ($500 x 12 = $6000) suggests replacement could be the better value. This rule is a guideline, but factors like system efficiency also play a role.
- Energy Efficiency: Older systems are significantly less efficient than newer, ENERGY STAR® certified models. Replacing an old unit can dramatically reduce your energy consumption and lower your utility bills.
- Future Reliability: A new system comes with a fresh warranty and the expectation of reliable performance for many years, avoiding the uncertainty and stress of potential future breakdowns.
Our technicians can provide an honest assessment of your current system, outlining the costs and benefits of both repair and replacement options to help you make the best decision for your Ballwin home and budget.
HVAC Maintenance Plans
Regular maintenance is key to maximizing the lifespan, efficiency, and reliability of your HVAC system. Just like a car, your heating and cooling equipment needs routine check-ups to perform optimally. Our Maintenance Plan for Ballwin homeowners helps prevent unexpected breakdowns, ensures your system runs efficiently to keep energy costs down, and can catch minor issues before they become expensive repairs.
Our comprehensive tune-ups, included in the plan, involve thorough cleaning, inspection, and testing of key components. This includes checking refrigerant levels, cleaning coils, testing electrical connections, inspecting combustion systems, and verifying thermostat accuracy. Enrolling in our maintenance plan also provides benefits like priority service and discounts on parts and filters. Seasonal tune-ups in the spring for your cooling system and in the fall for your heating system are crucial for preparing your equipment for the demands of Ballwin's summer and winter weather.
Indoor Air Quality Solutions
Beyond temperature control, the quality of the air inside your Ballwin home impacts your family's health and comfort. Dust, pollen, pet dander, mold spores, and other pollutants can circulate throughout your home, potentially exacerbating allergies and respiratory issues. Given the humidity in the St. Louis area, managing moisture and preventing mold growth is also important.
We offer a range of indoor air quality solutions to help you breathe easier. These include Whole House Air Purifiers that filter out airborne contaminants and Whole House Humidifiers that can help maintain ideal humidity levels during dry winter months. Improving your home's air quality can lead to a healthier living environment and enhanced overall comfort.

Common HVAC Questions from Ballwin Homeowners
Many Ballwin residents have questions about their HVAC systems. Here are answers to some frequently asked questions:
Why is my AC running but not cooling?
This could be due to several issues, including low refrigerant levels from a leak, a clogged air filter blocking airflow, a frozen coil, or a problem with the compressor.
How often do I need HVAC maintenance?
It is generally recommended to have your system professionally checked twice a year – once in the spring before the cooling season and once in the fall before the heating season.
What are the signs I need a new HVAC system?
Look for an aging system (over 10-15 years), frequent breakdowns, rising energy bills, inconsistent temperatures, strange noises, or excessive dust.
What is the "$5000 rule" for HVAC replacement?
This informal rule suggests considering replacement if the cost of a repair multiplied by the age of the unit (in years) is $5000 or more. It helps assess if continued repairs are economically viable compared to the cost of a new system.
What is the most expensive part to replace on an AC unit?
The compressor is typically the most expensive component to replace in an air conditioning system.
