The Challenge: An Aging Heat Pump with a Refrigerant Leak

A homeowner in Hanover, Maryland, contacted Capital Heat Pumps after experiencing problems with her air conditioning system.

The home was equipped with an older Airtemp heat pump that had experienced recurring performance issues. Over time, these problems had caused the homeowner to lose confidence in the system’s reliability.

Our team was initially called out for a no-air-conditioning service call.

During our diagnostic inspection, we discovered that the system was losing refrigerant due to a leak in the indoor evaporator coil.

Refrigerant leaks can cause several performance and reliability concerns, including:

• Reduced cooling capacity and inconsistent indoor comfort.
• Longer system operating times.
• Reduced energy efficiency.
• Increased stress on the compressor.
• Additional repair expenses as the system ages.

While replacing the leaking coil was an option to consider, the homeowner was concerned about continuing to invest money into equipment that had already caused repeated problems.

She wanted a more dependable, long-term solution rather than another repair that would leave the rest of the aging system in place.

Our Recommendation: Repair or Replace the Existing Heat Pump?

At Capital Heat Pumps, we believe homeowners should understand their options before investing in major HVAC repairs or replacements.

After identifying the refrigerant leak, we discussed the condition of the existing Airtemp system and the available repair and replacement options.

Although repairing the leaking coil could address the immediate refrigerant issue, it would not eliminate the age-related concerns associated with the remaining equipment.

The homeowner considered the potential cost of future repairs, the reliability of the existing system, and her long-term comfort needs.

Rather than continuing to put money into a system she no longer trusted, she decided to move forward with a complete heat pump replacement.

After reviewing our recommendations, the homeowner selected Capital Heat Pumps and a new Trane heat pump system for the project.

Our Solution: Complete Trane Heat Pump Installation

1. Replacing the Aging Airtemp System with Trane Equipment

Our team removed the existing Airtemp heat pump equipment and installed a new Trane heat pump system.

Trane was recommended as a replacement option to provide the homeowner with modern heating and cooling equipment backed by established manufacturer support.

The new heat pump provides both heating and cooling through one integrated system, allowing the homeowner to maintain year-round indoor comfort.

By replacing the entire system rather than repairing only the leaking coil, the homeowner could start fresh with updated equipment instead of continuing to rely on aging components.

2. Upgrading the Outdoor Equipment Pad and Support Legs

An important part of this installation involved improving the outdoor heat pump’s mounting structure.

We installed a new equipment pad and support legs to provide a stable, properly elevated foundation for the Trane outdoor unit.

These improvements were intended to:

• Provide stable support for the outdoor equipment.
• Elevate the unit above the equipment pad.
• Improve clearance beneath the heat pump.
• Help reduce prolonged exposure to standing water and ground-level moisture.
• Support proper drainage and long-term equipment maintenance.

Proper outdoor equipment placement is particularly important for heat pumps because they operate during both the heating and cooling seasons.

During winter heating operation, heat pumps periodically enter defrost cycles, producing water that needs to drain away from the outdoor unit.

Providing suitable elevation and drainage clearance helps support reliable operation throughout the year.

3. Installing a New Attic Drain Pan

Because the indoor HVAC equipment was located in the attic, condensate management was another important consideration.

We installed a new auxiliary drain pan beneath the indoor equipment to provide an additional layer of protection against potential condensate leaks.

Attic HVAC installations require special attention because a blocked drain line or condensate overflow can cause water damage to ceilings, insulation, and other finished areas below.

The new drain pan helps contain water if a condensate drainage problem occurs, reducing the risk of water escaping directly into the attic.

4. Adding a Moisture Safety Sensor for Additional Protection

Along with the new drain pan, we installed a moisture safety sensor designed to detect water accumulation.

If water reaches the sensor, the safety control can interrupt system operation to help prevent continued condensate production and reduce the risk of an overflow.

This provides an additional safeguard for the homeowner, particularly because the indoor equipment is installed above finished living space.

The combination of a new auxiliary drain pan and moisture safety sensor helps protect the surrounding property from condensate-related water damage.

While these components cannot prevent every possible leak, they provide valuable protection when properly installed and maintained.

Planning Ahead Instead of Continuing Costly Repairs

One of the most important aspects of this project was the homeowner’s decision to plan for the future.

The original service call began as a cooling problem caused by a leaking indoor coil. However, the homeowner recognized that repairing one component would still leave her with an older system that had already experienced reliability issues.

Instead of continuing to invest in equipment she had little confidence in, she chose to replace the complete system.

The new Trane installation also provided an opportunity to improve supporting components that contribute to long-term reliability, including the outdoor mounting structure and attic condensate protection.

This project wasn’t simply about replacing a leaking coil. It was about helping the homeowner move forward with a heating and cooling system she could feel more confident in.

The Results: A New Trane Heat Pump with Improved Equipment Protection

The completed installation provided the homeowner with a new heating and cooling system and several important supporting improvements.

Project highlights included:

• Diagnosed a refrigerant leak in the existing Airtemp system’s indoor coil.
• Replaced the aging Airtemp heat pump with a new Trane heat pump system.
• Installed a new outdoor equipment pad.
• Added support legs to elevate and stabilize the outdoor unit.
• Installed a new auxiliary drain pan beneath the attic HVAC equipment.
• Added a moisture safety sensor for condensate overflow protection.
• Addressed both immediate cooling concerns and long-term equipment reliability considerations.

By combining new equipment with improved installation details, Capital Heat Pumps provided a more comprehensive replacement solution designed around the homeowner’s needs.

Why Proper Heat Pump Installation Matters

Choosing a quality heat pump is only one part of a successful HVAC replacement.

Proper installation practices, equipment support, condensate drainage, and safety controls all play important roles in long-term system performance.

For homes with HVAC equipment located in the attic, condensate protection is especially important. A simple drainage failure can potentially cause significant property damage if water is allowed to accumulate unnoticed.

Similarly, outdoor heat pump equipment should be installed on a stable foundation with appropriate clearance and drainage provisions.

At Capital Heat Pumps, we evaluate these installation details as part of our replacement recommendations because a properly installed system involves more than just the equipment itself.
