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, Milford, 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, a Mitsubishi Ductless Pro Preferred Dealer, and an Armstrong Air Dealer. Although these are our primary brands, we do install other brands depending on your space and cooling requirements.

What should I do to prepare for my air conditioner replacement?

Getting a new air conditioner is exciting, and our professional technicians are here to help make the installation process seamless. With that said, there are a few things you can do before our experts even arrive:

  • Clear the Area: Make sure the area around your current air conditioning unit is clear of any obstructions. This gives our air conditioning installation technicians easy access to the equipment and provides them with plenty of space to work in.
  • Have a Plan for Kids and Pets: Keep your loved ones safe by having a plan for them on installation day. Let your kids know to stay clear of the work area and keep your pets on leashes or in their kennels.
  • Prepare Access Points: Our professionals will need clear access to your home, so make sure the driveway is clear for their vehicles and create an unobstructed path to the furnace or air handler, as well as the breaker box. If there are any locked gates or doors, unlock them ahead of time or make sure someone is available to grant access.
  • Make a List of Questions: Prepare a list of questions about the new system that you can ask your technician on the day of installation. Our technicians will be happy to address your concerns and provide you with all the information you need.

How do I know which cooling system is right for my home?

With so many options available, it can often feel like selecting the right air conditioner for your home is an impossible task. Fortunately, our professionals are here to help. Our HVAC Installation Specialist will evaluate several factors, including the size of your home, your cooling needs, and energy efficiency preferences. Based on this information, we’ll recommend the perfect system for your needs. Contact our home A/C installation team in Lewes, DE, for a consultation, and we’ll guide you through the selection process.

Where is the best place to install an air conditioning unit?

Location is not just important in real estate! For A/C units, the ideal spot is somewhere with good airflow, out of direct sunlight, and away from debris. Typically, this means the side or back of your house. Our HVAC technicians in Lewes, DE, will determine the right spot for your unit so that you can rest assured your system will operate efficiently for the extent of its life.
