Signs It’s Time for a New Air Conditioning Installation
Is your old air conditioner giving you constant trouble? It might be time to consider a new A/C installation from our team in Lewes, DE.
Here’s a closer look at the signs you need 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.
- Frequent Repairs: 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 a new installation 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. An upgraded unit can help you achieve consistent cooling throughout your home.




How to Choose the Right Air Conditioner for Your 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:
- Size of Your Home: Air conditioners are measured in BTUs (British Thermal Units), which determine how much space they can effectively cool. A unit that’s too small will struggle to keep your home comfortable, while one that’s too large can cycle on and off too frequently, leading to uneven temperatures and higher energy costs.
- Energy Efficiency Requirements: Energy-efficient units might cost more upfront, but they can save you a lot in the long run. Plus, your installation of a high-efficiency HVAC system may qualify for available tax credits and rebates. We’ll help you choose a unit with an appropriate SEER (Seasonal Energy Efficiency Ratio) rating that effectively keeps your home comfortable without breaking your budget. We can also help you determine if upgrades such as variable-speed motors or smart thermostats are necessary.
- Home Layout and Existing Ductwork: For central systems, we’ll make sure your ductwork is in good condition to avoid losing cool air through leaks. If your house (the space you are trying to cool) doesn’t have ducts, a ductless mini-split might be a more practical option.
Based on this information, we’ll recommend the perfect system for your needs. Contact our A/C installation team in Lewes, DE, for a consultation, and we’ll guide you through the selection process.
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.

Our 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.
