Frequently Asked Questions
How do I know if I should repair or replace my air conditioner?
How long should an air conditioner last?
There isn't one answer that fits every home. If your system is older, requires frequent repairs, struggles to cool evenly, or your energy bills continue to increase, replacement may provide better long-term value. Our technicians explain both options honestly so you can make the decision that's right for your home.
Most central air conditioning systems last between 12 and 18 years when properly maintained. Actual lifespan depends on installation quality, maintenance, usage, and environmental conditions.
How much does a new air conditioner cost?
Every installation is different because every home is different. Factors that affect investment include:
• Home size
• System capacity
• Efficiency rating
• Existing ductwork
• Electrical requirements
• Indoor equipment compatibility
After evaluating your home, we'll provide straightforward pricing with multiple options whenever appropriate.
How long does an AC installation take?
Most residential installations are completed in one day. More complex projects involving ductwork, electrical upgrades, or additional equipment may require additional time.
What size air conditioner do I need?
Can I replace only the outdoor AC unit?
Bigger isn't always better.
Oversized equipment cycles on and off too frequently, while undersized equipment may struggle during hot weather.
We perform a proper system evaluation and sizing calculation to recommend equipment designed specifically for your home's needs.
Sometimes, but not always.
Modern systems are designed to work as matched indoor and outdoor equipment. Replacing only one component can reduce efficiency, performance, and warranty coverage.
We'll explain whether replacing one component or the complete system makes the most sense.
What SEER rating should I choose?
Do you offer financing?
Higher SEER ratings provide greater energy efficiency but also come with a higher initial investment.
We'll explain the differences between available efficiency levels and help you determine which option provides the best value for your home and budget.
Yes. Financing options are available for qualifying repairs and system replacements. We'll help you explore available options so you can choose a payment solution that fits your needs.
Will a new air conditioner lower my electric bill?
Do I need to replace my furnace at the same time?
In many cases, yes.
Newer systems are significantly more efficient than equipment installed 10–20 years ago. Actual savings depend on your existing equipment, home insulation, thermostat settings, and overall system condition.
Will you remove my old air conditioner?
Yes.
We'll safely disconnect, remove, and properly dispose of your old equipment as part of the installation process.
Not always.
If your furnace is relatively new and compatible with the new air conditioner, replacement may not be necessary. If both systems are nearing the end of their service life, replacing them together often provides better efficiency and long-term value.
Do new air conditioners come with warranties?
Yes.
Manufacturer warranty coverage varies depending on the equipment selected. We'll review available warranty information before installation so you understand exactly what's included.
How soon can my new system be installed?
Installation timing depends on equipment availability and scheduling. We'll always work to complete your installation as quickly as possible while maintaining the quality of our work.
What happens during an installation appointment?
typical installation includes:
• Removal of existing equipment
• Installation of new components
• Electrical and refrigerant connections
• System startup
• Performance testing
• Thermostat verification
• Complete cleanup
• Homeowner walkthrough
People Also Ask
Is it worth replacing a 15-year-old air conditioner?
Many homeowners find replacement worthwhile once systems reach 15 years of age, especially if repairs become frequent or cooling performance declines. We'll help you compare repair costs versus replacement value.
What is the average life expectancy of a central air conditioner?
Most systems last between 12 and 18 years with regular maintenance.
What size AC unit does a 2,000-square-foot house need?
Square footage alone isn't enough to determine sizing. Proper equipment selection considers insulation, windows, ceiling height, orientation, and many other factors.
Why is professional installation important?
Even premium equipment can underperform if installed incorrectly. Proper airflow, refrigerant charge, electrical connections, and commissioning all play an important role in efficiency and reliability.
