Signs You Could Benefit From Air Conditioning Installation Services

Is your old air conditioner giving you constant trouble? It might be time to consider a new A/C installation. Here are some signs that you need our air conditioning installation services:

  • Inefficiency: If your energy bills have been soaring and your cooling system struggles to maintain a comfortable temperature, it could be a sign that your A/C unit is no longer efficient and needs to be replaced by a professional A/C replacement contractor.
  • Frequent Repairs: Constant repairs can be costly and frustrating. If your air conditioner requires frequent fixes and the A/C repair costs are adding up, it might be more cost-effective to invest in air conditioning replacement services.
  • Age of the System: As air conditioners age, their efficiency declines. If your system is over 10 years old, it’s worth considering an A/C installation or replacement from our pros in Lewes, DE, to take advantage of the latest energy-efficient technologies.
  • Uneven Cooling: If certain areas of your home feel significantly warmer or cooler than others, it could indicate an issue with your air conditioning system. A new central air installation can help you achieve consistent and balanced cooling throughout your home.

If any of these issues sound all too familiar, don’t hesitate to reach out to our A/C installation and replacement company in Lewes, DE, for professional solutions. In addition to Lewes, we proudly serve Rehoboth Beach, Dewey Beach, Harbeson, Milton, Georgetown, Millsboro, Bethany Beach, Ocean View, Fenwick Island, Dagsboro, Selbyville, Millville, and Frankford, DE.

Protect Your Central Air Installation With Preventive Maintenance

Running your air conditioner without maintenance is akin to driving your vehicle without oil changes. As time passes, your risk of a breakdown increases substantially. Although it’s an upfront cost, preventive A/C maintenance is an investment that helps you avoid high cooling costs, frequent breakdowns, and premature replacements. Remember to schedule A/C maintenance at least once a year — preferably in the spring.


How often should I replace my air conditioning system?

On average, A/C units last around 10-15 years. However, the lifespan can vary depending on factors such as usage, maintenance, and the quality of the unit. If your A/C system is older and showing signs of inefficiency or frequent breakdowns, you may want to consider an air conditioner replacement to improve your home’s comfort and reduce energy costs.

Can I install a new A/C unit myself?

A/C installation is a complex process that requires specialized knowledge and skills. It’s always best to hire a professional A/C installation company like Alltemp Air to ensure optimal performance and warranty coverage for your new A/C unit.

What brands of A/C systems do you install?

Alltemp Air is an American Standard Customer Care Dealer and a Mitsubishi Ductless Pro Preferred Dealer.

How much does an A/C installation or replacement in Lewes, DE, cost?
