Here are a few of the many air conditioning replacement services in Sussex County, DE, that we provide:

Central Air Conditioning Installation

A central air conditioning system uses a duct system to regulate the air throughout a designated space. It is one of the more expensive and time-consuming air conditioner options but proves highly effective when complete. To install a central air conditioner, you will need to schedule an initial consultation with our Sussex County team. Central AC installation can be a complex process since the system must attach to your existing ductwork while the indoor unit is replaced.

We will inspect your space and make assessments to ensure we can install everything according to your specifications.

Heat Pump Installation

If your ancient central air conditioning system is sucking up your time and money without providing any actual comfort, it may be time to consider a different type of AC unit. A heat pump system serves as both an air conditioner and a heat source in your home, eliminating the need to install dual HVAC systems. Not only do heat pumps provide the convenience of a combined cooling and heating unit, but these sophisticated systems offer some serious energy efficiency benefits as well. Most importantly for homeowners, these units are extremely low-maintenance, easy to install, and require minimal service or repair. To learn how our efficient new heat pumps can help you save big bucks, contact our Sussex County HVAC team now for a free estimate!

Ductless Mini-Split System Installation

As its name states, a ductless mini-split air conditioner system requires no ducts, unlike a central AC unit. This efficient type of air conditioner can go on the wall or ceiling in multiple areas, providing “zoned” cooling. Like with all systems, you can control the temperature through the thermostat, but with this type of system, you can monitor and change the temperature in a few rooms at once. You will be able to manage many spaces and achieve comfortable temperatures to your liking with a convenient and effective ductless split system!

Wall Unit Installation

These units also do not require ducts but have no wall-mounted thermostats to control temperatures like ductless systems do. Wall unit systems have manual controls and work well for new room additions. As their name suggests, they are typically wall mounted, but can sometimes be placed in other locations. Many modern wall unit models provide a cost-effective option for strict budgets while sharing many benefits of more expensive air conditioning systems. Our team can quickly and easily help you and your family with wall unit installation and offer competitive, affordable pricing for your new AC unit.

6 Signs It’s Time for a New AC Unit

What do heat pumps, central AC systems, and ductless AC systems have in common? Their limited lifespans. Unfortunately, no AC system can provide cooling power forever. And after an air conditioning unit has exceeded its service lifespan, it begins costing you more money than it’s worth to keep it alive.

Is it time to think about a new AC installation? There are several issues that your AC unit may develop that point to severe problems. Book service ASAP with our Sussex County residential air conditioning installation and replacement company if you notice any of the following danger signs:

  • Your unit is 15 years old or older, and it is increasingly hard to find compatible parts for repair.
  • Your AC system struggles to cool your home during the summer months or doesn’t blow cool air at all.
  • The SEER (Seasonal Energy Efficiency Ratio) rating of your unit is below 13 (this indicates that your unit is inefficient). A modern new air conditioner will save you a significant amount of money on energy bills.
  • The cost of air conditioning service is becoming equivalent to the cost of purchasing a new unit or the cost to install a replacement.
  • During the spring or summer, you spend more money and time on AC repair or maintenance than you do enjoying a working AC unit.
  • You are tired of using a central air unit or depending on a portable AC unit. In this case, we can recommend other AC units that may or may not connect to your existing ductwork. Ductless split systems are particularly advantageous if you are interested in not having to install ducts or lug a portable unit around through multiple rooms of the house.

Frequently Asked Questions (FAQs)


Should I repair or replace my air conditioning system?

If you’re trying to decide between air conditioner replacement or repairs, your best choice is to consult an established heating and air conditioning installation company in Sussex County. Most air conditioning units last 10 to 15 years, depending on annual routine maintenance checks and careful attention. One person’s central AC unit might last nine years while another person’s heat pump might last 16, so it’s important to speak with technicians about your options. We can help you discover the best options for your air conditioner and remove your old unit safely.

What is the average cost for air conditioning replacement?

Much like how we can’t provide you with a quote for repair or maintenance service until we actually see your HVAC unit, we cannot provide an “average cost” of replacing your air conditioning system either. All air conditioners are slightly different, therefore no two AC installation costs will be the same. Your AC system has its own quirks and qualities, and the price of air conditioner replacement will also depend on the type of new system you are interested in since some cooling systems are more expensive than others.

If you’d like a quote for replacing your air conditioner, contact our Sussex County HVAC company today. We can suggest models that suit your budget and keep your house comfortable,  and we stock a variety of high-efficiency systems that will reduce your energy bills. Just give us a call, and we’ll visit your home to provide you with information about the AC systems we offer, the approximate cost to install the HVAC system of your choice, and ways to keep your new system running for as long as possible.

Can I perform AC installation or repair myself?

If your air conditioner isn’t working properly, attempting DIY system repairs or maintenance to restore your system’s cooling capacity can be tempting. However, system repairs are more complex than you think. We know our customers love to save money, but replacing your system is a job best left to experts.

It is always better, safer, and more effective to leave air conditioning services to a company that specializes in them. Installing AC systems can be dangerous and expensive when done alone, and you will not have access to the same level of knowledge that licensed professionals do. Find the most up-to-date information, suggestions, and recommendations by hiring a trusted Sussex County air conditioning team to replace your HVAC unit.

It is not wise to replace or repair your AC unit yourself because:

  • It’s much easier than you think to make mistakes during the HVAC installation process — and often, these mistakes are costly ones. As a result, you may lose more money than if you hired expert technicians for service, or end up dealing with an uncomfortably hot home.
  • Performing HVAC repair or replacement takes time, strength, and energy you may not have. Installing AC units is a multi-person job that can be quite physically intense.
  • Cooling system repair or replacement requires parts and tools that are not available on the consumer market or are only available for a high price, meaning that DIY AC costs can mount quickly.
  • Without the personal protective equipment that technicians utilize, cooling system repair and replacement can be dangerous. Putting in a new AC system can expose you to gas lines, electrical components, circuit breakers, bulky overhanging ductwork, and other safety hazards.
  • DIY HVAC repairs or maintenance can result in decreased unit efficiency, costing you money and causing you headaches for many years to come.

Saving a few bucks up front on AC installation costs may seem appealing, but these and other drawbacks end up turning DIY into more of a burden than a benefit for almost all of the homeowners we’ve met. In summary, you should always leave HVAC system installation to the pros… trust us when we say you’ll be glad you did!

Professional and knowledgeable heat and ac company. Family operated company with family oriented values. Top flight saved the day for me when the company I originally hired to install my new ac central unit took off without completing the job. Top flight stepped right in, corrected and finished the job just as the weather was heating up. They also have improved the way I heat my house. Best heat/ac company I have ever worked with while owning many homes throughout the years. Thank you Top Flight!

The other day, when temperatures were in the teens, I woke up to 54 degrees in my house. I went on line to look up HVAC services and saw that Top Flight had many excellent reviews. So I called them. A couple of hours later, Isaiah and Tyler came to my house. I have to say that it was one of the best experiences, if not the best, that I have ever had with a contractor or service person. They were here all day. Isaiah explained everything to me in detail and encouraged me to ask questions. He was so patient and so nice. Of course, they fixed the problem and gave me some good advice. He was very professional but easy going and well-informed. Also, the prices are very reasonable. I highly recommend this company.

We were going through a total nightmare trying to find a company to fix our HVAC system. We tried 3 different companies that took our money and left us with a system that would stop working within a month after they said it was fixed. Top flight found the problem the 1st time they looked at it. It's now been running for almost a year with no problems. Isiah and this company are the best. We highly recommend them. Thank you Top Flight.

I Highly recommend Top Flight! I called for service at the beginning of the cooling season. Technician came on time, inspected and cleaned the main two heat exchanger zones, checked all the return filters, measured the temp at each supply output and then inspected and cleaned a mini split. He took his time but was really efficient, thorough, clean and knowledgeable. Had great air conditioning all summer! I signed up for their service plan and will be scheduling our heating/fall call after Thanksgiving.

Top Flight is exactly that! Tyler Powell was the technician sent to maintain my very old furnace. He was professional, informative and personable! He let me know what to expect from the furnace and I was pleased with his evaluation. There was no upselling. He, with the owner Ryan, came up with 7 quotes for different brands and efficiencies of furnaces that I requested.The ladies in the office did everything they could to fit me in the schedule!

I have Top Flight Heating & Air do my annual maintenance on both my central A/C inside the main house and the Mitsubishi A/C unit in our sunroom. Isaiah and Joey are really knowledgeable and listen to your needs. I had a severe attic condensation pipe break causing major ceiling repair in my living room. Isaiah found the leak and suggested redirecting it towards another area of the attic for a better flow to the outside. It has so far worked great. I'm very pleased dealing with Christina in the office. I highly recommend this company.
