An all-in-one HVAC unit heats and cools your property from a single system, so you get one installation, one thermostat, and one maintenance visit. For many homes and businesses, that means less equipment, simpler control, and lower upfront costs than buying a separate heater and air conditioner.
Indoor heating and air conditioning keep winter storms and summer heatwaves at bay. You’ll find furnaces and air conditioners in every make and model, plus systems that combine both. SM Mechanical Services is a family-owned, licensed and insured team that works on all makes and models. We help clients compare options honestly before they buy.
Key Points
- An all-in-one HVAC unit handles heating and cooling from one system instead of two.
- One outdoor unit means one installation session and less yard space.
- A single thermostat controls both heating and cooling.
- Buying one unit costs less upfront than buying a separate heater and air conditioner.
- Annual maintenance keeps an all-in-one system running efficiently.
What Is an All-in-One HVAC Unit?
An all-in-one HVAC unit is a single system that both heats and cools your property, in place of a separate furnace and air conditioner. Most all-in-one setups fall into one of three types:
- Packaged Unit: The heating and cooling components share one outdoor cabinet that connects to your ductwork, which frees up indoor space.
- Heat Pump: One outdoor unit moves heat into your home in winter and out of it in summer, paired with an indoor air handler. Learn more about heat pump installation and replacement.
- Ductless Mini-Split Heat Pump: An outdoor unit connects to wall-mounted indoor units, so it works in homes without ductwork. See our ductless AC installation and repair options.
A heat pump uses electricity to move existing heat from one place to another rather than generate new heat, according to the U.S. Department of Energy.
What Are the 6 Advantages of an All-in-One HVAC Unit?
An all-in-one HVAC unit saves on installation, space, energy, temperature control, upfront cost, and maintenance. Every system has advantages and drawbacks, so here are the main benefits first.
#1: Single Installation
An all-in-one HVAC unit needs only one installation session. The system uses a single outdoor unit, so technicians connect one unit to your ductwork instead of two, which reduces overall installation time. Ask your HVAC installer for an estimate of the installation time for your property.
#2: Improved Space Efficiency
An all-in-one HVAC unit takes up less space than a two-unit setup. All-in-one units are generally larger than units that only heat or cool, but they still save yard and garden space. A single unit is also easier to conceal behind fencing or another cover.
#3: Lower Energy Bills
An all-in-one HVAC unit is designed to limit energy waste. Engineers build modern units with improved compressors and more sensitive thermostats to cut waste as much as possible.
Multi-unit HVAC systems consume more energy than single-unit systems. Part of the reason is that the indoor thermostat and other components must communicate with two separate systems. The units in a multi-unit setup also may not be designed to work efficiently together.
#4: Convenient Temperature Control
An all-in-one HVAC unit runs on one central thermostat and remote. Separate heating and cooling units may need two different thermostats, which makes efficient temperature control harder. With one system, you switch between heating and cooling and set your temperature in one place.
#5: Lower Initial Costs
An all-in-one HVAC unit usually costs less upfront than a separate heater and air conditioner. If you live or do business where the seasons change, your property needs both heating and cooling. Buying one unit is cheaper than buying two, and you save on installation costs too.
Whatever system you choose, get an accurate estimate from experienced HVAC technicians before you buy a system or schedule service.
#6: Reduced Overall Maintenance
An all-in-one HVAC unit takes less time and money to maintain than a multi-unit system. Heating and air conditioning systems need regular upkeep to run efficiently. On a single unit, technicians inspect ductwork connections, motors, refrigerant, and more in one visit, so inspections, maintenance, and repairs cost you less.
What Are the Drawbacks of an All-in-One HVAC Unit?
An all-in-one HVAC unit is not the right fit for every property. Weigh these tradeoffs before you decide:
- When the shared system breaks down, you can lose heating and cooling at the same time.
- Replacing the unit means replacing your heating and cooling together.
- Outdoor packaged units sit exposed to snow, rain, and summer heat year-round.
- Heat pumps work harder in very cold weather, so some homes pair them with a backup heat source.
A licensed HVAC technician can look at your home, your ductwork, and how you use your system. That review helps you choose between an all-in-one unit and separate equipment, such as a new furnace installation paired with central AC.
Getting the Most Out of Your All-in-One HVAC System
You deserve to get the most out of your heating and air, no matter which system you choose. Keep up with scheduled inspections, maintenance, and repairs. Experienced HVAC technicians can change filters quarterly, inspect the ductwork for debris, clogs, or damage, and replace lost coolant during routine AC maintenance visits.
Don’t wait until your HVAC system stops working to call a professional. Regular maintenance is the best way to prevent breakdowns and damage. Call the experts if you notice any of these signs:
- Burning smells
- Rattling noises
- No cold air or hot air
- No air movement
- Failure to turn on or off
- Poor temperature regulation
Multi-unit and all-in-one HVAC systems are both a significant investment. Protect yours with annual maintenance and an inspection before the system’s first use in a while.
