Residential Air Conditioning: Everything You Need to Know Before Installing or Replacing Yours. With summers getting hotter — including here in Massachusetts — air conditioning has gone from being a luxury to a necessity in many homes. But choosing the ideal system, knowing when it’s time to replace the old one, and understanding the costs involved still raise questions for many homeowners.
In this blog, we’ll answer the main questions about residential air conditioning and show you how to make the best decision for your home.
1. Types of Air Conditioning: Which One is Best for You?
– Window Units
• Simple installation and lower cost
• Ideal for small apartments or individual rooms
• Limited power and aesthetics
– Standard Split
• Outdoor + indoor unit
• Economical and quiet
– Mini-Split (Ductless)
• No ductwork needed
• Can cool multiple rooms, and individual rooms has their own thermostat
• Highly efficient — ideal for homes without central systems
– Central (Ducted)
• Cools the entire home
• Works with a thermostat, usually one per floor
• Requires ductwork (can be more expensive)
2. When Is It Time to Replace an Old Air Conditioner?
If your unit:
– Is more than 10 years old
– Consumes too much energy
– Makes excessive noise
– No longer cools as before
– Constantly needs repairs
…it’s time to consider replacement. New models are much more efficient and quieter, and many qualify for financial incentives such as Mass Save rebates.
3. How Much Does It Cost to Install an Air Conditioner?
Prices vary depending on the type of system, home size, and installation complexity. Here are some averages:
| Type | Estimated Cost (installed) |
| Window | $300 – $800 |
| Split | $2,000 – $4,500 |
| Mini-Split (1 zone) | $3,000 – $6,000 |
| Central System | $6,000 – $12,000 |
Tip: You may qualify for rebates of up to $10,000 with efficiency programs like Mass Save — especially when installing mini-splits or replacing old systems.
4. Energy Efficiency: Save in the Long Run
Look for ENERGY STAR® certified units, which consume less energy and deliver better performance. The higher the SEER (efficiency rating), the more efficient the equipment.
Additionally, when combined with smart thermostats, you can automate cooling and avoid waste.
5. Professional Installation: Why It’s Essential
Installing air conditioning is not just “plug and play.” A poorly done installation can cause:
- Refrigerant leaks
- Excessive noise
- Poor performance
- Higher energy bills
- Loss of manufacturer’s warranty
That’s why you should always hire a licensed and experienced company, such as The Power Pro Electrical Services.
