HVAC Frequently Asked Questions Answered

Many homeowners don’t think much about their HVAC systems until they break down. However, learning about your system and how it works can help you to feel more confident calling a technician for service.

Learn about zoning, air filter options, energy efficiency ratings and how to schedule routine duct cleaning. This information will also provide peace of mind when it comes time to replace your system.

1. What’s the difference between a ductless system and a central system?

The main difference between a central system and a ductless mini-split is that a central AC uses air ducts to distribute cooling throughout the home. A ductless system uses individual indoor blower units that connect to a single outdoor unit with a conduit, which carries a power cable and refrigerant line.

A ductless system is ideal for older homes that cannot accommodate air ducts, as well as new additions to your home such as sunrooms and garages. They’re also great if your family members have different comfort preferences, as they allow you to zone in your home with multiple indoor blower units that can be individually controlled.

Additionally, a ductless system is easier to install than a central system. Ductless systems require only a small hole in the wall for installation and can be easily connected to existing wiring, which makes them a cost-effective solution.

2. What’s the difference between a ductless system and a central system?

The main difference between a ductless system and a central system is that a ductless mini-split system does not use ducts. Instead, they move refrigerant between indoor units through a conduit running through the wall or ceiling of your home.

A ductless system also allows you to set temperature zones so different rooms can be cooled independent of each other. This prevents family squabbles over the thermostat and lets you save energy by shutting off units in rooms that aren’t being used.

Plus, ductless systems are much easier to maintain because there’s no need to clean air ducts that can harbor mold and mildew. If you’re adding a room to your home or remodeling an unfinished space into an en suite for an elderly relative, a ductless system is a great option.

3. What’s the difference between a ductless system and a central system?

Many homes in South Jersey and southeastern Pennsylvania still rely on traditional HVAC systems that utilize forced air with ducts to spread heated or cooled air throughout their properties. However, those in need of HVAC equipment expansion might be able to save on the cost of upgrading to a new centralized system by installing a ductless mini-split system instead.

A ductless system has an outdoor condenser unit and a smaller indoor blower we call a head, which is mounted either high on the wall or under the ceiling. They move refrigerant through slim tubing between the two units, and cool air blows out directly from the head—no ductwork required.

Ductless systems are highly energy efficient, and Carrier’s ductless models can even achieve ENERGY STAR qualification. Additionally, they offer zoning capabilities for precise climate control; easier installation compared to replacing ductwork; and a sleek appearance that doesn’t detract from your property’s interior design.

4. What’s the difference between a ductless system and a central system?

A ductless system (also known as a ductless mini-split) provides heating and cooling support for areas in your home that don’t have or can’t accommodate air ducts, such as sunrooms, bedrooms, garages and more. They’re also ideal for older homes that may have ductwork leaks that reduce efficiency and comfort.

Ductless systems use multiple indoor units that connect to a single outdoor unit via refrigerant lines. They’re available in a variety of designs to suit your home decor, with options for wall-mounted and floor models.

Ductless systems offer improved energy efficiency and lower utility bills, and many homeowners can qualify for tax credits or rebates. They’re more expensive upfront than traditional central systems, but are cheaper to run long-term. They also require less maintenance.

5. What’s the difference between a ductless system and a central system?

A standard central system consists of a network of ducts that deliver warm and cool air throughout the entire home. A ductless system, on the other hand, is an HVAC option that eliminates the need for ductwork.

The indoor units for a ductless system hang on the wall or stand on the floor, and you can choose from covers that blend in with your home’s decor. The outdoor unit, called a compressor, is located outside the home.

Ductless systems have the ability to utilize zoning, which allows different areas of the home to be set at different temperatures. This can reduce energy costs and increase comfort. It can also cut down on allergens like dust and pollen that can irritate your nose, eyes, and throat.
