Hely Heating and Air Conditioning has been serving communities like Lemay since 1969, providing expert AC repair, installation, and maintenance services tailored to keep your home cool and comfortable.

Fast and Reliable AC Repair in Lemay
A malfunctioning air conditioner can quickly turn a comfortable home into an unbearable one, particularly during the hottest months. If your AC is showing signs of distress – perhaps it's blowing warm air, making strange noises, cycling on and off frequently, or causing your energy bills to spike unexpectedly – it's time to call for AC repair. Ignoring minor issues can often lead to more significant, costly breakdowns down the line.
Common AC problems we address in Lemay include:
- Refrigerant Leaks: Low refrigerant levels mean your system can't cool effectively. This often indicates a leak that needs professional detection and repair, not just a simple "recharge."
- Frozen Evaporator Coils: Restricted airflow (often due to dirty filters) or low refrigerant can cause the indoor coil to freeze, preventing cooling.
- Drainage Problems: Clogged condensate drains are common and can lead to water damage or system shutdown.
- Electrical Issues: Problems with capacitors, relays, or wiring can prevent the unit from starting or running correctly.
- Sensor Problems: The thermostat or evaporator coil sensor can malfunction, causing the system to cycle improperly.
- Worn Components: Belts, motors, or other moving parts can wear out over time, reducing efficiency and potentially causing breakdowns.
Our technicians arrive equipped to diagnose the issue quickly and accurately. We explain the problem clearly and provide transparent options for repair. We understand that some AC issues can't wait, which is why we offer 24/7 emergency repair services to the Lemay community, ensuring you're not left without cool air for long.
Professional AC Installation and Replacement in Lemay
While repairs can often extend the life of your current system, there comes a time when AC replacement is the most cost-effective and beneficial option. If your air conditioner is more than 10-15 years old, requires frequent or expensive repairs, or is simply not keeping your home comfortable anymore, investing in a new unit makes sense.
Upgrading your air conditioning system in Lemay offers numerous benefits:
- Improved Energy Efficiency: Modern AC units boast significantly higher SEER (Seasonal Energy Efficiency Ratio) ratings than older models, leading to lower energy consumption and reduced utility bills.
- Enhanced Comfort: New systems provide more consistent temperatures, better humidity control, and quieter operation.
- Increased Reliability: A new unit comes with the peace of mind of fewer breakdowns and potentially comprehensive warranty coverage.
- Environmental Benefits: Lower energy consumption reduces your home's carbon footprint.
At Hely Heating and Air Conditioning, we specialize in AC installation for a variety of system types suitable for Lemay homes, including:
- Central Air Conditioning: The most common system, using ductwork to distribute cool air throughout the home.
- Heat Pumps: Efficient systems that provide both cooling and heating, ideal for Missouri's climate where both needs are present.
- Ductless Mini-Splits: Perfect for homes without existing ductwork, additions, or for zoning specific areas for cooling.
Our installation process begins with a thorough assessment of your home's size, layout, insulation, and cooling needs. This allows us to recommend the appropriately sized and most efficient system for your specific situation. We handle the entire installation process, from removing the old unit to expertly installing the new one, ensuring all connections are secure, the system is properly charged, and everything is tested for optimal performance. We work with trusted manufacturers like Goodman and Daikin, known for their reliability and impressive warranty options, including Limited Lifetime Warranties on key components for certain models.
The Importance of AC Maintenance in Lemay
Regular AC maintenance is not just a recommendation; it's an essential investment in the longevity and efficiency of your cooling system, especially given the demands placed on units during Lemay's hot summers. Just like changing the oil in your car, routine AC tune-ups help prevent unexpected breakdowns, improve performance, and extend the lifespan of your equipment.

Financing Options and Potential Rebates
We understand that investing in a new AC system is a significant decision. To help make comfort affordable for Lemay residents, we offer various financing options.
