What Should I Know Before Buying a New Air Conditioner?

Yes, choosing the right air conditioner requires careful consideration of size, efficiency, cost, and installation. The wrong AC unit can lead to high energy bills, poor cooling performance, and frequent repairs. Here's everything you need to know to make the best decision for your home.

How much does a new air conditioner cost?

Expect to pay between $4,500-$10,000 total for a new AC system. This includes two separate costs: the unit itself ($3,000-$7,000) and professional installation ($1,500-$3,000). You can save money by purchasing wholesale units, but installation costs may be higher due to additional labor requirements.

What size air conditioner do I need for my home?

The correct AC size depends on your home's square footage, insulation, and cooling load requirements. An undersized unit won't cool your home effectively, while an oversized unit wastes energy and creates humidity problems.

Get a professional load calculation

A certified HVAC contractor must perform a load calculation to determine the proper size. This assessment considers your home's dimensions, insulation levels, window placement, and local climate conditions to recommend the ideal AC capacity measured in BTUs or tons.

What SEER rating should I look for in an air conditioner?

Choose an AC unit with a SEER rating between 14-22 for optimal energy efficiency. The minimum required SEER rating is 13, but higher ratings (14+) significantly reduce energy costs. Energy-efficient units with 16+ SEER ratings can cut cooling costs by 20-30% compared to older models.

Are split-system air conditioners better for harsh weather?

Yes, split-system air conditioners are designed to withstand severe weather conditions without additional protection. These outdoor units are built with weather-resistant materials and don't require covers during storms or winter months. In fact, covering outdoor units can damage the system by restricting airflow and trapping moisture.

How often does my new air conditioner need maintenance?

Schedule professional maintenance annually to maintain warranty coverage and optimal performance. Most AC manufacturers require yearly maintenance to keep warranties valid. Professional HVAC maintenance prevents small issues from becoming expensive repairs and extends your system's lifespan by 5-10 years.

How do I find a qualified air conditioner installer?

Research local HVAC contractors through referrals, online reviews, and Better Business Bureau ratings. Choosing the right HVAC installer is as important as selecting the unit itself.

What to ask potential installers

Request quotes from 2-3 contractors that include specific makes and models, installation details, and warranty information. Verify licensing, insurance, and manufacturer certifications before making your decision. Compare total costs, not just unit prices, as installation quality affects long-term performance.
