We provide all types of air conditioning service and can work with any and all HVAC systems, including everything from older HVAC units to brand-new state-of-the-art ones. Whatever your cooling unit needs may be, our Sussex County team can get the cool air flowing again.

During each tune-up, our reliable heating and air technicians will clean and lubricate the components of your AC unit, ensuring that it runs smoothly and efficiently. We’ll recalibrate faulty thermostats, check your unit is operating safely, and install a new AC filter or clean your current filter so that your indoor air quality remains healthy. Our technicians can also recommend system repairs or new system installation as necessary.

The Importance of Routine Air Conditioning Tune-Ups

If you’ve never invested in air conditioning maintenance services in Sussex County, DE, you’re missing out on an ample opportunity to improve the lifespan of your HVAC unit and keep it working properly for as long as possible. Routine AC system maintenance is crucial because it offers these (and more) benefits…

Improved Energy Efficiency

If you aren’t having our expert technicians service your home’s cooling systems, you’re probably paying too much for cool air. A well-maintained air conditioner unit uses less energy to cool your home, significantly lowering your energy bills. In addition, an HVAC system that performs at its optimal capacity doesn’t waste refrigerant or cooling energy, which means you can count on it to reliably keep your Sussex County home cool.

Increased Equipment Lifespan

Regular maintenance services from an AC professional can help extend the lifespan of your AC system. By catching small problems early on and scheduling minor repairs before they become major issues, you can avoid costly emergency repairs or even premature replacement of your unit. Anyone who’s had their AC break down in the middle of a hot summer night already knows that a cooling emergency is no joke. Adding many years to the service lifespan of your system helps you avoid emergency breakdowns, which can wreak havoc on your everyday life.

Improved Indoor Air Quality

A dirty or clogged air filter can reduce indoor air quality and cause health problems for those with allergies or respiratory issues. During a tune-up, our heating and air conditioning technicians will replace or clean your air HVAC unit’s filter, improving the air quality in your home. Having your air filter regularly replaced will also put less stress on your system, which means you’ll require HVAC services less frequently.

Peace of Mind

Knowing that your central AC unit, heat pump, or other system has been professionally inspected and maintained by our technicians will give you peace of mind during hot summer days when you rely on it most. You’ll have confidence that your HVAC system is working properly and won’t break down unexpectedly or cause a comfort emergency.

Signs Your Air Conditioner Could Use a Tune-Up

Knowing if your air conditioner needs emergency repairs is usually simple, but it’s not always as easy to notice when your system could use maintenance services. Here are a few signs that your air conditioning unit might need tune-up services from our Sussex County professionals:

Poor Airflow

If you notice weak or inconsistent airflow from your vents, it could be a sign that your air conditioning unit needs maintenance. During your tune-up services appointment, one of our experienced technicians will inspect and clean the components of your system to ensure that air is flowing freely.

Air Conditioning Unit Blowing Warm Air

If your air conditioner is blowing warm air instead of cool air, there could be several issues at play. The cause of the heat is often low refrigerant levels, dirty coils, incorrectly programmed thermostats, or other common problems that can be addressed during routine HVAC services. We can also assess if your cooling system needs emergency repairs or should be completely replaced. If you aren’t sure what you are looking for, our HVAC services team is happy to help you select the most efficient heat pump or mini-split system for your needs.

Unexpected Noises

Unusual sounds coming from your air conditioner, such as rattling or banging, often indicate loose parts or other mechanical issues. If this HVAC emergency is happening to you, get in touch with us ASAP. Our affordable routine HVAC services can help you identify and fix these problems before they become more serious.

Unpleasant Odors

Does it seem like something died in your air conditioner, and the smell gets more pungent every week? Foul smells coming from your vents could mean mold or bacteria has grown inside your AC unit. Professional cleaning during a tune-up or emergency appointment can eliminate these odors and improve indoor air quality. Once your unit’s clean, we’ll follow up with a new filter installation to restore that “fresh” feeling once again.

Higher Energy Bills

If you’ve noticed an increase in your energy bills without any changes in usage habits, it could mean that your AC unit is working harder than it needs to due to inefficiencies caused by a lack of maintenance. If you’re interested in saving the maximum amount of money, our Sussex County cooling experts can also recommend efficient unit installation (such as heat pumps or mini-splits).

Frequently Asked Questions (FAQs)


How often should you have AC maintenance?

You should schedule AC maintenance twice per year. Book HVAC maintenance in the fall and spring to keep your unit working correctly during summer and winter.

What maintenance does your AC unit need?

Typically, each air conditioning unit needs different treatments depending on its wear and tear and lifespan. However, every unit needs a yearly check-in and tune-up. No matter what type of system you have, we will thoroughly clean it, including all coils, filters, and other important components.

How can I maximize AC efficiency?

The best way to maximize AC efficiency is to clean your system thoroughly. This way, every part functions at its prime.

Dirty or old air filters are a common culprit when AC units stop working at maximum efficiency. This is especially true if the filters have gone several years without being cleaned or have too many pleats for filtration. Our team knows how to choose the best filters for your unit and your personal needs, so give us a call today!

Do I need a yearly refrigerant top-up?

Most of the time, leaks result in needing refrigerant faster than usual. Therefore, if you constantly need to top up your refrigerant, you might have a leak on your hands. This depletion of refrigerant acts as a sign to call a technician to stop the leak at its source. Get a free service estimate from Top Flight today or schedule service online ASAP.

Tyler from TopFlight was fantastic. He earned a new service subscription customer.A prior tech from Air Temp solutions left the previously working system disabled and not working. Their follow up tech quoted $1,250 for a new thermostat and thermostatic board. Needless to say I searched for another company.Tyler diagnosed a simple but easily overlooked problem. The system was restored with only a service call.Big call out to Tyler and Top Flight!

Isaiah was my technician who performed a routine AC checkup. He was professional, knowledgeable, and polite. I was impressed with the service so I signed up for the annual plan and have high expectations if I ever run into any issues. Top flight was recommended by a friend who had issues and used several companies that couldn’t fix the problem before finding Topflight that did fix the problem.

We had Top Flight install a new HVAC system. Isaiah and Tyler were great at the installation. They cleaned up after the job which was nice. The plus is the system is nice and quiet compared to our old system and the balancing they did reduced the temperature extremes in our upstairs vs downstairs.

Very professional and explained everything. I love the fact that they gave me different quotes and I did not feel like they were just trying to get money from me. Our house is only 4 years old and have had nothing but problems with the company that put the system in the house. I FINALLY have peace of mind knowing it was done right. I also really liked the yearly maintenance contract and it was not a crazy amout of money. Thank you for your trained technicians.

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.

As new customers with Top Flight, we were visited by Ryan for an initial system inspection and a review of the various customer programs that Top Flight offered.While Ryan's extensive experience and knowledge of our HVAC system were clearly evident, his ability to explain and demonstrate issues or items in normal, understandable ways impressed us the most as a new customer.Top Flight's office staff has been equally helpful. Christina, in particular, has been exceptionally helpful with all our new customer setups and arrangements.We highly recommend that Top Flight be included in anyone's short-list of an Honest and Polite Customer-Focused service from a well-established local firm.

Average. (I don't give extra stars to companies who demonstrate basic professionalism in being on time or having reasonable customer service). This company is VERY EXPENSIVE! They offer a discount to customers to "become members," which makes their service (which includes way more service than I want or need) appear cheaper by charging smaller monthly payments which add up to much more over a year than others charge for 2 annual maintenance checks. ($420/year for an 1800 sf house, compared to $180/year for the same sized house in Maryland.) This monthly payment plan makes it very difficult to track what service is already paid for and what is being prepaid. Thus they have pioneered a way to keep their hand in your wallet for months after the service has already been provided. No thanks. I don't buy it. They did allow me to cancel -which is apparently unusual for them- although they did not provide a refund for payments I made already for service that I won't get.

What can I say.....BEST HVAC COMPANY EVER! Since moving to this area I have be unable to find a company to actually listen to me and do proper work. Upon a recommendation from a friend I tried this company out and I was not disappointed. Ryan was extremely professional in diagnosing and fixing my issue. He made the whole process easy and as painless as possible. He gave me many options on new systems and even informed me on state and federal rebates in our area. Isaiah is an excellent technician who loves this work and really did an amazing job. He is also by far the most polite server provider I've ever had in my house period. Taylor rounded out this trio and made this an amazing experience. I'd recommend this company to anyone who doesn't want to be pressured by pushy sales people, "know it all" technicians, and "I know better than you" owners.

One of the only companies in the county you can trust to do a honest job in the hvac industry. I had three companies out to try and fix my issue and they either failed to diagnose it properly or lied and said it was an expensive repair in order to upsell a brand new unit. Isaiah quickly identified a bare wire shorting out against a copper pipe in the fan unit and fixed it charging me the proper amount for the service . He is a young smart and determined technician, but most of all he is honest.

In a nutshell, this company is fantastic!If you're still reading I'm going to elaborate on just why that is. We opened a new small business here in Lewes, DE and when we went seeking a local company to take care of our system they came highly recommended. Ryan reached out to me directly on Facebook to introduce himself and the team. Vey quickly he set me up with Taylor who got the ball rolling. She listened to what we were looking for and sent Mike out to have a look. He was professional and knowledgable in his diagnosis of our newly installed system. For no charge they told me what needed to be repaired and we set a day to do so. Mike and Josh came back (sooner than the appointment time I might add) and did a thorough job gettin our system up and running. Ryan and I talked again about the work and he gave us a very fair price.I am now a subscribing customer and intend to be so long as we are doing business here. I have nothing but great things to say about the entire experience and strongly recommend this team to any business in the state!
