FAQs About HVAC – Heating, Ventilation & Air ConditioningFAQs

HVAC – Heating, Ventilation & Air Conditioning — buying, delivery, and installation

We carry central HVAC systems built for whole-home comfort — from 2-ton heat pumps to 5-ton A/C and gas combos. Browse heat pump split systems (up to 18.1 SEER2), A/C and gas combos, packaged units, and hybrid setups from MRCOOL, Goodman, and Senville. Whether you're replacing an aging system or starting fresh, all systems ship free to the contiguous US. Financing is available on qualifying orders, and our HVAC experts are on live chat to help you size and choose the right 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.

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.

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.

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.

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.

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.

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.
