Repair vs. Replace: Making the Right Decision
Deciding whether to repair your current AC or invest in a new one can be challenging. We help Richmond Heights homeowners make an informed choice by considering factors like:
- Age of the System: Systems older than 10-15 years are often less efficient and more prone to breakdowns.
- Frequency of Repairs: If you're facing constant repair bills, replacement might be more cost-effective in the long run.
- Cost of Repair: A major repair that costs a significant percentage of a new unit's price might indicate it's time to replace. A common guideline is the "$5000 Rule": If the age of the system multiplied by the cost of the repair exceeds $5,000, it may be more financially sensible to replace the unit rather than repair it.
- Energy Efficiency: Older units have lower SEER ratings, leading to higher energy bills. A new, high-efficiency system can offer significant long-term savings.
We'll assess your current system, discuss your comfort needs and budget, and provide a recommendation that makes sense for your Richmond Heights property.

Energy Efficiency & Cost Savings in Richmond Heights
Upgrading to a high-efficiency air conditioning system is one of the best ways Richmond Heights homeowners can reduce energy consumption and lower their utility bills. Understanding SEER (Seasonal Energy Efficiency Ratio) and the newer SEER2 ratings is key to maximizing savings. Higher SEER/SEER2 ratings indicate greater efficiency.
Investing in a high-efficiency AC system can also make you eligible for various financial incentives.
Access Local Rebates and Financing
We help you navigate available options to make energy-efficient upgrades more affordable:
- Ameren Missouri Rebates: Ameren Missouri offers rebates for residential customers who install eligible high-efficiency HVAC equipment, including central AC units and heat pumps meeting specific SEER2, EER2, and HSPF2 requirements. Rebate amounts vary based on the equipment's efficiency level. We can help you understand which systems qualify for these valuable local rebates.
- Federal Tax Credits: Federal tax credits, like the potential $600 credit mentioned on our site, may be available for installing qualifying energy-efficient HVAC systems.
- Inflation Reduction Act (IRA) Rebates: While specific Missouri IRA rebate programs are still being developed and rolled out, the act is intended to provide future opportunities for significant rebates on energy-efficient home upgrades, including HVAC systems, for eligible households. We stay informed about these developments to help our customers take advantage of future savings.
In addition to rebates and tax credits, we offer Financing options to help you manage the cost of a new AC installation or replacement, ensuring you can achieve the comfort you need without financial strain.
Types of AC Systems We Service & Install
Finding the right cooling system for your home depends on factors like size, layout, existing ductwork, and specific comfort needs. We service and install various types of systems suitable for Richmond Heights properties:
- Central Air Conditioning: The most common type, using ductwork to distribute cool air throughout the entire home. Ideal for homes with existing duct systems.
- Heat Pumps: A versatile system that provides both cooling in the summer and heating in the winter, operating as a highly efficient electric heater by transferring heat rather than generating it. A great option for efficiency, especially in milder climates or where natural gas isn't the primary heating source.
- Ductless Mini-Splits: Perfect for cooling individual rooms, additions, or older homes without existing ductwork. These systems are highly energy-efficient and offer precise temperature control in specific zones.
