Central Split System FAQs
What is a central HVAC system?
A central HVAC system uses a network of ducts to heat and cool your entire home from a single unit. It typically consists of an outdoor condenser (or heat pump) and an indoor air handler connected by refrigerant lines, distributing conditioned air through vents in every room.
What's the difference between a heat pump system and a traditional A/C system?
A heat pump can both heat and cool your home by reversing its refrigerant cycle, making it a year-round solution without a separate furnace. A traditional central A/C system only cools — you'd pair it with a gas furnace or electric air handler for heating. Heat pumps are generally more energy-efficient in moderate climates.
What size central HVAC system do I need?
Sizing depends on your home's square footage, insulation, climate zone, and ceiling height. As a general rule: 1 ton of cooling covers roughly 400–600 sq ft. A 2,000 sq ft home typically needs a 3–4 ton system. Use our live chat to speak with an HVAC specialist who can help you size correctly.
Can I buy a central HVAC system online and install it myself?
You can purchase central HVAC equipment online and save significantly versus buying through a local contractor. However, installation must be performed by a licensed HVAC technician in most states — the refrigerant handling and electrical work require certification. We recommend buying the equipment here and hiring a local installer separately.
What SEER2 rating should I look for?
SEER2 (Seasonal Energy Efficiency Ratio 2) measures cooling efficiency — higher numbers mean lower energy costs. Federal minimums are 14–15 SEER2 depending on your region. For the best long-term savings, look for systems rated 16 SEER2 or higher. Many of our MRCOOL and Senville systems reach 17–18 SEER2.
Does Home Outlet Direct offer financing for central HVAC purchases?
Yes. Financing is available on qualifying orders, making it easier to invest in a high-efficiency central HVAC system without paying everything upfront. See our financing page for details on terms and eligibility.
Do central HVAC systems from Home Outlet Direct come with a warranty?
All systems come with the manufacturer's warranty. We also offer extended warranty and protection plans for added peace of mind. Brands like MRCOOL and Goodman are backed by industry-leading coverage.
What is a Goodman split system?
A Goodman split system is a central HVAC setup with an outdoor condenser and an indoor air handler or furnace. Together they provide whole-home heating and cooling, offering better efficiency and quieter operation than window units.
What SEER2 ratings do Goodman split systems come in?
Goodman central split systems range from 14.3 SEER2 up to 22.5 SEER2 depending on the model, with higher ratings meaning greater energy savings on monthly utility bills.
Do Goodman split systems come with a warranty?
Yes. Goodman offers industry-leading limited warranties — typically up to 10 years on parts when registered — giving homeowners long-term peace of mind on their investment.
What size Goodman split system do I need?
Sizing depends on your home's square footage. For example, a 1.5-ton system typically covers 600–1,000 sq. ft., while a 4-ton system suits 2,200–2,600 sq. ft. An HVAC professional can perform a Manual J load calculation for accuracy.
What refrigerant do Goodman central split systems use?
Current Goodman split systems use R-32 refrigerant, which has a lower global warming potential (GWP) than older R-410A systems, making them a more eco-friendly choice.
Can I install a Goodman split system myself?
Goodman split systems require professional installation by a licensed HVAC technician, both for safety and to keep the manufacturer's warranty valid.
Does Home Outlet Direct offer free shipping on Goodman split systems?
Yes, Home Outlet Direct offers free shipping on Goodman central split systems along with wholesale pricing, making it one of the most affordable ways to purchase a full HVAC kit online.
