• Repeated repairs whose combined costs approach 50% of a new system value

When one or more of these issues surface, HEP technicians conduct a detailed assessment to confirm whether repair or full replacement offers the better long-term value.

HEP's HVAC Replacement Process

Every successful installation follows a structured plan that leaves no variable unexamined. HEP’s methodical approach ensures the new system fits the home as precisely as a custom-tailored garment.

Initial Assessment and Load Calculation

A home evaluation starts the process. Rather than relying on square footage alone, HEP completes a Manual J load calculation that incorporates:

• R-value of existing insulation
• Window type, quantity, and orientation
• Air leakage rates identified by blower-door testing
• Occupant density and heat-generating appliances
• Shading from nearby trees or structures

This data underpins correct sizing, preventing the common pitfalls of oversizing (shorter life, humidity issues) or undersizing (inadequate heating/cooling).

Equipment Selection Optimized for Helenwood Homes

With load numbers established, HEP selects equipment meeting or surpassing the latest federal efficiency guidelines. Choices include:

• Two-stage gas furnaces with 96%+ AFUE for homes using natural gas or propane
• Variable-speed heat pumps capable of maintaining heat down to sub-freezing temperatures
• Dual-fuel systems automatically switching between electricity and gas for optimal cost efficiency
• High-efficiency air handlers equipped with electronically commutated motors (ECMs)

Selection extends to indoor air quality add-ons such as media air cleaners, UV lights, and whole-house dehumidifiers, all sized to integrate seamlessly.

Professional Installation and Testing

Installation day follows best-practice protocols:

1. Protective floor coverings and furniture shields are placed in work zones.
2. Old equipment is disconnected, evacuated (if containing refrigerant), and removed for environmentally safe disposal.
3. New pad or hanging brackets are set level to support the condenser or heat pump unit.
4. Refrigerant lines are brazed with nitrogen purge to prevent scale formation.
5. Duct connections are sealed with mastic or approved foil tape, then insulation is replaced or upgraded.
6. Electrical circuits are checked for proper amperage draw and breaker sizing.
7. Vacuum evacuation reaches industry-standard 500 microns or below before refrigerant release.
8. System starts under manifold gauge monitoring to verify correct superheat and subcooling.

Post-Installation Support

Upon completion, HEP provides system documentation, filter schedules, and demonstration of thermostat functions. Technicians collect performance data to create a baseline, ensuring future tune-ups can pinpoint deviations swiftly.

Energy Efficiency Advantages of a New HVAC Unit

Replacing an outdated system yields measurable efficiency benefits that show up on monthly statements.
