What’s Included With Air Conditioner Installation?

Installing an air conditioner starts with choosing equipment that fits your home. An oversized or undersized system can lead to comfort problems, frequent cycling, poor humidity control, and unnecessary energy use.

Heritage provides air conditioner installation in New Hampshire for homeowners replacing existing equipment or adding central cooling.

Your installation may include:

• Evaluating your home’s cooling needs
• Reviewing existing HVAC equipment
• Checking accessible ductwork
• Determining appropriate system capacity
• Removing old AC equipment
• Installing the new indoor and outdoor equipment
• Making refrigerant and electrical connections
• Installing or connecting compatible controls
• Testing system operation
• Checking airflow and cooling performance
• Reviewing basic system operation with the homeowner

The exact installation depends on your house and existing HVAC setup. Homes without central cooling may require additional work compared with a straightforward replacement.

What Are the Signs You Need a New Air Conditioner?

An air conditioner does not always need replacement simply because it has stopped working. Some problems can be corrected with a repair, especially when the equipment is otherwise in good condition.

Replacement may become worth considering when:

• Your AC needs repairs frequently
• The system struggles to cool your entire home
• Some rooms remain much warmer than others
• Cooling costs have increased
• The system runs for long periods without reaching the thermostat setting
• The equipment is getting older
• A major component has failed
• The system uses outdated equipment or technology
• You want to add cooling to a home that does not currently have it

A licensed HVAC professional can inspect your current system before recommending replacement.

Repair or Replace Your AC?

The right choice depends on the condition of the equipment, the type of repair needed, and how well the system meets your home’s needs.

Repair may make sense when:

• The problem is limited to a repairable component
• The system has otherwise been performing well
• Repairs have not become frequent
• The equipment still meets your cooling needs

Replacement may make sense when:

• Breakdowns happen repeatedly
• A major repair is needed on aging equipment
• The system cannot cool the house properly
• You are already planning other HVAC upgrades
• Your current system no longer fits your comfort needs

Heritage can explain the available options and provide upfront pricing before you decide how to proceed.

Why Does AC Sizing Matter?

Air conditioners are not chosen based only on the square footage of a house. Several parts of the home affect how much cooling it needs.

An HVAC professional may consider:

• Home size
• Layout
• Insulation
• Window quantity and condition
• Sun exposure
• Existing ductwork
• Ceiling height
• Air leakage
• Current HVAC equipment

An oversized AC can reach the thermostat setting too quickly and shut off before removing enough indoor humidity. An undersized unit may run for long periods and still struggle to cool the home.

New Hampshire’s summer humidity makes proper sizing particularly important. The goal is to install equipment that can maintain both comfortable temperatures and appropriate moisture levels.

What Happens During an AC Installation?

Knowing what to expect can make replacing your cooling system easier.

1. Home and System Evaluation

The HVAC professional reviews your current equipment and discusses any comfort problems you have experienced. This is also a good time to mention rooms that stay too warm or other concerns.

2. Equipment Selection

System options are based on the home’s needs and existing HVAC setup. You can review the proposed equipment and upfront pricing before installation.

3. Old Equipment Removal

For replacement projects, existing AC equipment is disconnected and removed as appropriate.

4. New Equipment Installation

The indoor and outdoor components are installed and connected. Necessary refrigerant, drain, electrical, duct, and control connections are completed.

5. System Testing

The completed system is started and checked for proper operation. Airflow, temperature, controls, and other operating conditions can be reviewed before the installation is finished.mit-related requirements when necessary.

FAQs

• How do I know what size air conditioner my home needs?

  System size depends on more than square footage. Insulation, layout, windows, sun exposure, ductwork, and other factors can affect cooling needs. A professional assessment helps determine the appropriate capacity for your home.

• Can I replace only the outdoor AC unit?

  It depends on your existing HVAC equipment and the compatibility of the components. Indoor and outdoor equipment are designed to work together, so an HVAC professional should evaluate the complete system before recommending a partial replacement.

• How long does an air conditioner installation take?

  Installation time varies based on the home, equipment, and amount of work required. Replacing an existing system may be more straightforward than adding central AC to a home that does not already have the necessary infrastructure.

• Should I replace my furnace when I replace my AC?

  Not automatically. The age, condition, compatibility, and expected service life of both systems should be considered. If both pieces of equipment are aging, discussing them together may help you plan future HVAC work.

• When is the best time to install a new AC?

  You can replace an air conditioner whenever the existing system no longer meets your needs. Planning replacement before the hottest part of summer can reduce the chance of being without cooling during a heat wave.

Recently I ran out of water at home which, I believed was my well pump. Contacted Gelinas, now Heritage, and shortly after the technicians were at my home. Ben quickly assessed the problem, found it was my pressure tank. He replaced my tank and by early afternoon my water was restored. Ben was very professional and his work was exceptional.
