Signs You Need a New AC

Over time, your air conditioner’s components wear down. Before your AC fails entirely, consider replacing your unit to avoid unnecessary utility and repair costs.

Homeowners should lean toward replacement instead of repair if:

  • Your air conditioner is over 10 years old: Older units are prone to refrigerant leaks, compressor failures, and
  • Your cooling costs have increased: If you’re flagging higher-than-average energy bills without a change in usage, an inefficient AC may be to blame.
  • You need frequent AC repairs: If the repair cost exceeds 50% of the unit’s value, you’re better off investing in a replacement.
  • Your air conditioner is too big or small for your home: Save on utilities and feel more comfortable with an AC model that’s properly sized for your household.

Benefits of AC Replacement

Although there is a perceived cost and hassle to upgrading your home’s air conditioner, there are countless payoffs. Homeowners who invest in a new AC unit enjoy:

  • Reduced risk of breakdowns
  • Fewer repairs
  • More reliable home comfort
  • Increased home value
  • Lower utility costs
  • Reduced carbon footprint

We’re ready to install your new AC. Call Len The Plumber Heating & Air at (800) 950-4619(800) 950-4619 to schedule an air conditioner replacement for your Mid-Atlantic home.

  • Your budget: Consult us on your price range so that we can meet your goals. We offer financing options on approved credit to make the process as easy as possible.
  • SEER rating: All AC systems are assigned a Seasonal Energy Efficiency Rating. A higher rating means a more energy-efficient unit.
  • Home size: Your property’s square footage impacts the unit capacity you’ll need to stay cool. Unit size is measured in British Thermal Units.
  • Home layout: If you have a two-story home, you may need two smaller air conditioners for zoned cooling. You could also consider ductless mini-splits if you don’t have room for ductwork.
  • Compressor speed: Enjoy greater temperature control with single-stage, two-stage, or variable-speed compressors.

Frequently Asked Questions

What steps do I need to take to replace my AC?

  • Call for an air conditioner evaluation to determine if replacement is best
  • Work with your HVAC team to choose your new air conditioner model
  • Determine payment — whether that’s paying upfront or taking advantage of financing options
  • Clear the area around your indoor air handler and outdoor unit to prepare for installation day

From there, your HVAC team will:

  • Disconnect ductwork, wiring, and refrigerant lines
  • Remove and dispose of your old system
  • Prepare the installation site
  • Install your new system
  • Connect ductwork, wiring, and refrigerant lines
  • Test your unit for proper function

Are there alternatives to central AC?

Yes! Ductless mini-splits offer customizable control over temperature zones without ductwork. Heat pumps are the most energy-efficient HVAC option, offering dual cooling and heating for year-round comfort.

Does a new AC increase home value?

You can get a 35% to 50% return on investment when you upgrade your air conditioner. If you’re selling your home, new HVAC replacements attract buyer interest with substantial energy cost savings. It’s one less expense and inconvenience they have to worry about.

Can I replace my AC myself?

No, not unless you’re a licensed HVAC professional. An air conditioner is a complex system that requires electrical wiring and refrigerant lines. Without qualified training, you risk injury and may void your manufacturer warranty.

How can I extend my AC’s lifespan?

Regular tune-ups are the key to extending the life of your air conditioner. You should schedule air conditioning maintenance every spring to help keep your unit in peak condition.
