Frequently Asked Questions (FAQs)


How do I know when it’s time to replace my air conditioner?

If you notice that your energy bills are unusually high or if your system needs frequent repairs, it may be time to replace your air conditioner. Additionally, if your system is more than 10 years old, it is a good idea to consider replacing it with a newer model that will be more energy-efficient and reliable.

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 type of air conditioning system should I choose?

The best type of air conditioning system for your needs will depend on the size and layout of your home as well as the climate in which you live. A professional HVAC technician can help assess your needs and recommend the best option for you.

I’m sure that a lot of HVAC Companies are similar to Top Flight. I called them and ask the to come out on a weekend because I didn’t have heat. While they were on their way I figured out that I had a bad contactor. When the guy arrived, I showed him the contactor. He didn’t have one in his van. So he had to go get one. He replaced it and checked over the rest of the system and say I was low on refrigerant. He came back two days later and added 1/4 lb of refrigerant. I paid $1,488 for them to replace 1 contactor and a 1/4 lb of refrigerant. I was totally RIPPED OFF. I definitely would not recommend them!
