In some circumstances, your AC unit may be too damaged for repairs to be worthwhile, and it may make more financial sense to invest in a new unit rather than paying for replacement parts. These cases often include situations where an AC unit can no longer remove humidity effectively from the home, multiple components of the unit need to be replaced, or you’ve already spent a fortune on repair service with no progress made.

If it does turn out that your AC system needs to be replaced, don’t sweat it! The Top Flight team is more than happy to walk you through the entire AC replacement process, including assisting you with selecting the right unit for your house, providing advice on energy efficiency and recommended maintenance intervals, and explaining the cost of service honestly and transparently.

Keeping Your AC Unit Healthy: A Homeowner’s Guide

While we’re always here to help with any and all of your air conditioner problems, there are also ways you can take care of your own air conditioning system Whether your home has window units or central air units, taking the time to inspect your AC unit occasionally makes a big difference…and that leads to fewer repair calls you’ll have to make in the future!

Homeowners should regularly assess their AC units at least twice a year to ensure they are running effectively. As a part of any at-home HVAC assessment, we recommend that homeowners check up on:

Air Filters

Depending on the manufacturer and material, you should change your AC unit’s air filters between once a month to about every three months. Individual air filter packaging identifies how often you should change each type of air conditioner filter. Clogged air conditioner filters can lead to less air flow and poor indoor air quality; in addition, a dirty filter can also reduce the life expectancy of your heating and cooling unit. Plus, who wants to breathe in all the gunk and grime that can build up inside a dirty air filter?

Thermostats

Your unit’s thermostat should display temperatures accurately and be able to maintain air conditioner settings with little input from you. Improperly functioning thermostats make your AC unit work harder to cool the space, which makes it much harder to save money on your energy bills. While checking your air conditioner thermostat, be sure to inspect the unit’s batteries in case they need to be replaced. Replacing the batteries often solves thermostat problems instantly, so be sure to learn what type of batteries your thermostat requires and keep a few on hand in case it starts misbehaving!

Outdoor Units

As part of regular maintenance, outdoor AC units should be kept debris-free. Debris can clog system filters and ducts, reducing the efficiency of the AC unit or causing damage. Over time, your system can even develop a problem lurking under the surface, leading to more than just reduced cooling capabilities. If your AC unit is filthy, it’s crucial to have it cleaned ASAP. Our HVAC service pros would be more than happy to tackle this job for you!

Signs You Need a Residential Air Conditioning Repair Company

If your air conditioner develops a problem, it’s essential to contact a professional AC repair company sooner rather than later for air conditioning repair services in Sussex County, DE. Contact our home air conditioning repair professionals ASAP if you spot any of the following common unit issues:

Frequent Cycling

Your air conditioning unit should cycle on when the temperature in your home rises above the set cooling temperature. Then, it should automatically cycle off once it reaches the adequate temperature. This is how cooling units are designed to work… in theory, that is. However, without regular maintenance, you might run into a problem known as short-cycling.

Your cooling unit is working insufficiently if it regularly cycles on and off. Short-cycling leads to uneven cooling in the home and periods in which hot air blows into the house. Frequent cycling also leads to more wear and tear on the system, reducing its lifespan and overall energy efficiency. If this problem is happening in your living space, contact our technicians for repairs or to discuss installing a new HVAC system.

Uneven Cooling or Hot Air Blowing From AC Unit

Most HVAC units — both heating and cooling systems — utilize condenser coils and compressors. The compressor and condenser coils in an air conditioning unit work together to remove heat from the air entering your home and turn it into cold air. When these components aren’t working properly, they cannot adequately cool the air coming into your home. Not only is this uncomfortable for the people in your home, but it can also cost you more in energy bills. If you experience this issue frequently, it’s time to get in touch with our service technicians to discuss repair or replacement options for your air conditioner.

Unit Freeze-Ups

As the intense heat of the summer begins in Sussex County, it can be tempting to keep your air conditioner on for as long as possible so that your home’s indoor temperature remains tolerable.  However, constantly running the unit to keep the home cool can lead to the condenser coils freezing up. The unit can stop working when the condenser coils freeze over, resulting in a lack of cool air during the summer.

To prevent condenser coil freeze-ups, monitor the coolant in your system and keep the AC system temperature above 70 degrees Fahrenheit. During your annual tune-up appointment, our expert technicians can check your equipment for signs of this common cooling problem and recommend any system repairs or replacement options. We specialize in condenser coil cleaning and condenser replacement for all types of units, including heat pumps, ductless mini-splits, central air units, and much more.

Unexpected Noises or Smells

HVAC equipment is far from noiseless, so certain air conditioner noises and smells are normal to experience in your home. For example, you may hear the fan blade spinning when you turn on the air conditioning. In fact, not hearing the fan blade spinning can be an indicator that the HVAC unit is off or the system is not functioning.

However, if something sounds or smells unusual, your air conditioning unit may have a dirty air filter, mechanical problem, or electrical issue. These issues can be minor and easy to repair, but problems can worsen quickly if you don’t book professional air conditioning system service. Before you know it, you could end up with poor indoor air quality, a refrigerant leak, a blown fuse, or a few hundred dollars worth of other damages. Contact a Sussex County professional for AC repairs as soon as you notice your air conditioning system malfunctioning.

Finding the Right Air Conditioning Company for Service

There are dozens of air conditioning repair, installation, and maintenance companies to choose from in the Sussex County area. While each company may offer unique services and deals, finding the right air conditioning service company is essential.  After all, the last thing you want when you pay to repair your AC system or install a new one is to get scammed out of your hard-earned cash!

Ways to find the right company for you include:

  • Review local company websites
  • Read online reviews
  • Talk with family and friends
  • Check for license numbers

What Makes Top Flight Different Than The Rest?

We’re Fully Licensed

All AC servicing companies must be fully licensed by the state they work in to provide heating and air conditioning services. Every state has different licensing requirements, but in general, licensing ensures that the company employs thoroughly trained and qualified maintenance technicians. Licensure also proves experience and skill so that homeowners can choose an AC repair service team with confidence.

Bonded

A bonded air conditioning service company purchases protection for the homeowner for the work or services provided. In case AC repair service does not work or damage occurs, the homeowners can seek compensation (such as having damaged or faulty air conditioners repaired or replaced free of charge).

Insured

HVAC companies must be insured to cover expenses for equipment damages or employee injuries that occur on homeowner property. The difference between being bonded and being insured is that insurance protects the company, and bonding protects the homeowner.

Certified Technicians

If technicians complete additional repair service training, air conditioning companies can be certified by manufacturers to repair and sell their specific units. This means technicians have been approved to install, maintain, repair, and replace that manufacturer’s air conditioners and understand proper installation practices, common issues, and standard equipment repair techniques.

Air conditioning service companies are not required to be specifically certified; however, certification does say a lot about technical skills and experience. At Top Flight, we’re proud to say that our team is certified to work with several top HVAC unit brands, so you can call us with confidence anytime you need to install, repair, or replace HVAC equipment!

Professional and knowledgeable heat and ac company. Family operated company with family oriented values.

Best heat/ac company I have ever worked with while owning many homes throughout the years. Thank you Top Flight!

Top Flight exceeded our expectations. We had an unexpected issue with our 4 year old system over the weekend and we were able to make an appointment easily online. Tyler (our tech) showed up on time. He was professional, courteous, knowledgeable and kept us informed the entire time he was troubleshooting and maintenancing our unit. He answered any questions we had as well as recommendations to ensure our system runs top notch. With that said we signed up for a maintenance plan the same day and definitely recommend them if anyone is looking for a HVAC company.

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!
