Benefits of Installing 3.5 Ton Gas Package AC Units for Homes in Las Vegas

Introduction to 3.5 Ton Gas Package Units

With summer temperatures frequently exceeding 100 degrees Fahrenheit, having a properly functioning air conditioning system is crucial for homes and businesses in hot climates like Las Vegas. One popular type of cooling system is the packaged unit, which contains the major HVAC components in a single cabinet. For medium-sized homes and commercial spaces, a 3.5 ton packaged gas unit can provide efficient cooling and heating.

What is a 3.5 Ton Package Unit?

The tonnage refers to the cooling capacity of an HVAC system. One ton of cooling equals 12,000 BTU (British Thermal Units) per hour. Therefore, a 3.5 ton packaged unit has a cooling capacity of 42,000 BTU per hour. This is suitable for cooling spaces between 1,500 and 2,000 square feet. Most package units range from 1.5 tons to 5 tons in capacity.

Package units get their name because all the major components - compressor, evaporator coil, condenser coil, and blower - are packaged into a single metal cabinet. This makes installation simpler compared to split systems. Goodman, Trane, and Carrier are popular brands for packaged units.

Benefits of a 3.5 Ton Gas Package Unit

There are several advantages to choosing a 3.5 ton packaged gas unit:

• All-in-one convenience - With a packaged unit, there is no need to install separate components.
• Energy efficiency - Newer gas pack units have efficiency ratings of 80% AFUE or higher.
• Lower installation costs - Package units require minimal ductwork and wiring.
• Versatility - Most units provide both heating and cooling.
• Quiet operation - New models are designed to operate more quietly.
• Cost-effective - Packaged systems generally cost less upfront than split ductless systems.

Key Components of a 3.5 Ton Gas Package Unit

Here are the main components found inside a typical 3.5 ton packaged gas heating and cooling unit:

• Compressor - The compressor circulates refrigerant and is driven by an electric motor. It generates hot, high-pressure vapor refrigerant.
• Condenser coil - The condenser coil allows hot refrigerant to dissipate heat, condensing it into a liquid state.
• Metering device - The metering device like a thermostatic expansion valve regulates the flow of refrigerant to the evaporator.
• Evaporator coil - Refrigerant absorbs heat and evaporates in the evaporator coil, creating a cooling effect.
• Blower - The blower pulls air across the evaporator coil and circulates conditioned air through ductwork.
• Gas Burner - Heating is provided by burning natural gas or propane to heat air blown across a heat exchanger.
• Controls - The thermostat, sensors, and switches help monitor and regulate system operation.

Typical Installation Process for 3.5 Ton Gas Package Units

Proper installation of a packaged unit helps ensure energy efficient operation and long equipment lifespan. Here are the key steps involved in installing a new 3.5 ton gas packaged AC unit:

1. The old AC unit is removed and disconnected from ductwork and electrical.
2. The new packaged unit is placed on a sturdy pad outside the home or on the roof.
3. The unit is connected to gas and electrical lines.
4. Ductwork is attached to direct airflow in and out of the packaged unit.
5. Condensate drainage lines are installed.
6. The thermostat and control wiring are connected.
7. The refrigerant lines are checked for leaks.
8. The gas and electrical supplies are turned on.
9. The unit is tested to ensure proper airflow and operation.
10. Any permits and inspections are finalized with the city.

When installed properly by experienced HVAC technicians, a new efficient 3.5 ton packaged gas unit can provide reliable cooling and heating for many years. Annual maintenance helps keep the system running at peak performance.

Cost to Install a 3.5 Ton Packaged Gas Unit

For a typical single family home, installing a new 3.5 ton packaged gas heating and cooling unit usually costs between $4,500 - $8,000. The final price depends on:

• Unit size and features
• Ductwork modifications needed
• Natural gas or propane fuel
• Hiring an HVAC contractor vs DIY install
• Local labor and material rates

Shopping for deals from reputable HVAC companies and getting quotes for the project cost can help find the best value. Many contractors offer financing options to help spread out the expense over time.

Maintenance Tips for 3.5 Ton Packaged Units

Regular maintenance is crucial to ensure efficient operation and long equipment life. Here are some important maintenance tips for 3.5 ton packaged AC units:

• Change air filters every 1-3 months during peak cooling season.
• Have a professional technician service the unit in spring and fall.
• Clean debris and vegetation away from the outdoor unit.
• Inspect refrigerant levels and duct connections annually.
• Check the condensate drain line is clear.
• Verify proper airflow at registers and vents.
• Monitor unusual noises or smells that could indicate a problem.
• Fix minor issues immediately to prevent bigger problems.

With proper installation, maintenance, and care, a new energy efficient 3.5 ton packaged gas heating and cooling unit can keep a home comfortable for over 15 years. Investing in HVAC upgrades like a new packaged unit adds value and reduces energy costs for years to come.
