Package Unit Installation
Your single system for both heating and cooling — expertly installed and financed.
All-in-One Comfort Solution
A package unit delivers complete home comfort in one compact, all-in-one outdoor system. Instead of separate indoor and outdoor air conditioning components, a package unit contains the compressor, condenser, evaporator coil, and furnace (or electric heating) all in one weatherproof cabinet. They’re efficient, space-efficient, and built for homes where space is a priority — especially single-story homes, mobile homes, or properties with limited outdoor placement options.
At Reliable Comfort Services, our team brings 50+ years of combined experience installing package systems across Middle Tennessee. Tempstar is our primary install brand for package units, offering a reliable platform with strong warranty coverage and available extended warranties. We’re also an LG Pro Dealer, and we partner with Wells Fargo, TVA Financing, and Synchrony so you can upgrade affordably. Our certified technicians understand the unique installation and maintenance needs of package units and ensure every system is configured for years of reliable operation.
Why Choose Us
Our team specializes in package unit installation and understands the engineering, efficiency, and space-saving advantages of all-in-one systems. When you choose us, you’re partnering with a team with deep, hands-on experience installing package systems and knows how to maximize their performance and lifespan.
Tempstar is the equipment we install most for package units and split systems, chosen for its reliable platform and strong warranty coverage.

We’re also an LG Pro Dealer, and Carrier and Trane equipment is available and serviced as well.
A package unit’s performance depends on proper ductwork routing from that single outdoor location to all areas of your home. We design and coordinate duct placement to ensure balanced air distribution, no pressure imbalances, and optimal efficiency. We seal ducts to prevent energy waste and test airflow from every register.
We hold a Tennessee Mechanical (HVAC) and Refrigeration Contractor License, full bonding and insurance, and a Better Business Bureau A- rating. Your package unit installation is backed by genuine credentials and the industry experience they represent.
As a Tennessee Valley Authority EnergyRight Quality Contractor, we’re committed to installing systems that reduce your heating and cooling costs. We understand package unit efficiency ratings and help you choose equipment that minimizes energy use while delivering comfort year-round.
Because a package unit is a complete heating and cooling solution, you’re replacing two separate systems in one installation, which appeals to budget-conscious homeowners. We work with Wells Fargo, TVA Financing, and Synchrony to offer flexible terms so financing fits your budget.

Our Process
We begin by understanding your home’s unique heating and cooling needs and evaluating your property for package unit placement. Our technician measures square footage, assesses insulation quality, checks window placement and sun exposure, and identifies any existing ductwork that can be reused or modified. Package units require careful outdoor siting — we look for level ground with proper drainage, adequate clearance for airflow, and positioning that minimizes noise while protecting the unit from weather exposure.
We also perform a detailed heating and cooling load calculation to determine the right-sized system. An undersized unit can’t keep up with Tennessee winters or summers; an oversized unit cycles inefficiently and wastes energy. This assessment is where proper engineering prevents costly mistakes later.
Once we understand your heating and cooling loads, we present package unit options — led by Tempstar, our primary install brand, with Carrier and Trane also available. We discuss fuel type (natural gas furnace, electric heating, or heat pump for maximum efficiency), AFUE ratings for heating efficiency, and SEER ratings for cooling efficiency. Choosing the right system involves balancing upfront cost against long-term energy savings.
We help you understand the trade-offs between a standard efficiency package unit and a high-efficiency model, and we review all financing options from Wells Fargo, TVA Financing, and Synchrony so cost doesn’t delay your comfort upgrade.
Before installation day, we prepare your site and coordinate any necessary permits, utility notifications, or electrical upgrades. We plan the ductwork routing from the package unit location throughout your home, schedule the removal of old equipment (if applicable), and ensure all necessary materials are on hand. We confirm the installation timeline with you in advance so there are no surprises.
If you’re upgrading from separate heating and cooling systems, modern refrigerants and ductwork may require modifications. We identify these during planning and discuss them clearly with you. Our goal is to ensure installation day is efficient, professional, and disruption-free.
On installation day, our certified technicians set the package unit on its outdoor pad with vibration isolation, route all refrigerant and ductwork connections, wire the thermostat and safety controls, and test every component to ensure optimal performance. This detailed, precision work requires expertise in both heating and cooling systems — we take the time to get every connection right.
Our team performs a complete startup sequence: cycling through heating and cooling modes, verifying that the thermostat controls temperature accurately, testing all safety shutdowns, and measuring airflow from every register. We take pressure and temperature readings to verify the system operates at design specifications.
Before we leave, we spend time with you so you understand how to operate your new package unit system. We show you how to use your thermostat, explain warranty coverage in detail, discuss filter replacement schedules, and outline seasonal maintenance basics. We answer any final questions and leave you with all documentation.
We also explain why annual maintenance is critical for package units — a fall heating tune-up before winter and a spring cooling tune-up before summer keep your combined system running efficiently, catch minor issues before they cause failures, and keep your warranty valid. Our maintenance plans make staying on schedule easy.
Protect Your Package Unit Investment
Once your new package unit is installed, staying on top of maintenance is critical for both heating and cooling performance. A fall heating tune-up and spring cooling tune-up keep your integrated system running efficiently, catch minor issues before they become failures, and keep your warranty valid.
Our maintenance plans make staying on schedule easy — and they offer repair savings if issues ever do arise.

Answering Your Questions
A package unit combines heating and cooling in one outdoor cabinet. Instead of an outdoor air conditioner and an indoor furnace, one integrated system handles both. They’re popular for space-saving, simpler installation routing, and lower maintenance costs since there’s one service point instead of two.
Modern package units offer efficiency ratings (SEER for cooling, AFUE for heating) comparable to separate systems. High-efficiency package units with heat pump technology can actually exceed the efficiency of gas furnace and air conditioner combinations, especially in mild climates. We help you compare options.
That depends on your home’s heating and cooling load — calculated from square footage, insulation, windows, sun exposure, and Tennessee’s climate. Oversizing wastes energy; undersizing can’t maintain comfort. Our load calculation determines the right size for your home and usage patterns.
Often yes, but ductwork must be modified to route from the single outdoor package location to all areas of your home. We assess duct condition, routing, and sealing needs during your estimate. Sometimes ductwork improvements enhance efficiency and comfort significantly.
We remove them safely and dispose of them responsibly. Refrigerant is captured and recycled, and metal and other materials are recycled where possible. Removal is included in our installation service with no additional cost.
Package units come with natural gas furnace heating, electric resistance heating, or heat pump technology (which heats by moving outdoor heat inside even in cold weather). Heat pumps are most efficient for Middle Tennessee winters but cost more upfront. We’ll discuss which option makes sense for your budget and climate.
Most package unit installations take one to two days, depending on whether you’re replacing an existing system or installing in a home without one. We’ll confirm the exact timeline during your estimate based on your ductwork requirements.
Yes. We work with Wells Fargo, TVA Financing, and Synchrony to offer flexible payment terms. Since a package unit replaces both heating and cooling, the combined investment appeals to many homeowners seeking financing options. We discuss terms before you commit.
A new package unit can be backed by three layers of coverage. First, a manufacturer parts warranty of up to 10 years when the equipment is registered — we handle registration and keep your documentation, since coverage varies by equipment and many warranties require it. Second, an optional third-party labor warranty of up to 10 years, covering repair (labor) costs for up to a decade. Third, No-Hassle equipment replacement on qualifying, select equipment, which replaces the unit rather than repairing it if a major component such as the compressor or coil fails within the coverage period. We also offer service agreements that extend coverage beyond the manufacturer’s terms.
Yes. Beyond the manufacturer parts warranty of up to 10 years when the equipment is registered, we offer an optional third-party labor warranty of up to 10 years, covering repair (labor) costs for up to a decade. Select equipment also qualifies for No-Hassle equipment replacement on qualifying, select equipment if a major component such as the compressor or coil fails.
With proper maintenance, package units typically operate reliably for 12–18 years. The key to longevity is annual heating and cooling tune-ups, regular filter changes, and prompt repair of any issues. Our maintenance plans help you maximize your system’s lifespan.
Yes. We service all brands and models of package units. If you need repair or maintenance after installation, we’re here to keep your system running smoothly. Our technicians understand the integrated design and can diagnose and repair heating or cooling issues efficiently.
Absolutely. Package units require both heating and cooling maintenance to operate efficiently and maintain warranty coverage. A spring cooling tune-up and fall heating tune-up catch problems early, reduce energy bills, and extend equipment life. Our maintenance plans include both seasonal checkups.
