very nice. Wish you would send alvan Foust for every HEP call gor me. Thank you for Hep services.

Trudy G.

My heating and air unit completely quit on me the other day. I called HEP as they were the only ones who could come out on a moments notice. Unfortunately I had to get a whole new heating and air system (the writing was on the wall for some time, I was just waiting for the inevitable). I was financed the same day (at 8pm!!) and set up the installation. I was told it would take 6 to 8 hours estimate for the work to be done. The gentlemen that came to install the unit (Javi and Eric(?)) came on time and were very friendly and courteous and knowledgeable. They had the old system removed and the new one installed in just a little over 3 hours. I was all around very impressed with the work that was done...from the person that took my phone call the other day, to the technician that came out to diagnose the problem and helped me get financed and the gentlemen that installed the new system. Everyone was personable and knowledgeable throughout the whole process. I would definitely recommend HEP to anyone that is in need of home service that you can't do yourself.

David F.

Reuben was professional and thorough—I will ask for him again! He arrived to install and was thorough and quick’

Step-by-Step HVAC Unit Replacement Process with HEP Company

Replacing an HVAC unit is a structured endeavor that demands planning, technical expertise, and attention to detail. HEP company follows a multi-phase framework to guarantee successful outcomes.

1. Comprehensive Assessment

Technicians perform an on-site evaluation, gathering information about:

Current equipment type, age, and performance history
Insulation levels, ductwork condition, and airflow balancing
Window orientation, occupancy patterns, and special comfort requirements

2. Precision Sizing and Equipment Selection

Using manual load calculations, the team selects an appropriately sized system. Factors considered include:

Square footage and ceiling heights
Local design temperatures
Solar gain and shading
Desired efficiency ratings and available fuel sources

3. Safe Removal of Existing Unit

Before installation begins, technicians:

Recover refrigerant in accordance with EPA regulations
Disconnect gas lines and electrical wiring
Protect flooring, walls, and surrounding areas from debris

4. Installation of New System Components

This phase includes:

Positioning indoor air handler or furnace on vibration-isolating pads
Setting outdoor condenser or heat pump for optimal airflow clearance
Connecting refrigerant lines with precise brazing and leak testing
Integrating compatible thermostats, smart sensors, and zoning controls

5. System Commissioning and Performance Verification

To confirm correct operation, HEP company technicians:

Verify refrigerant charge with subcooling and superheat measurements
Calibrate airflow to manufacturer specifications
Test safety controls, limit switches, and drain lines
Program thermostat schedules for energy savings

6. Job-Site Clean-Up and Client Orientation

Upon completion, the crew removes packaging and old equipment for proper disposal, then walks the client through:

Filter replacement intervals
Routine maintenance tasks

Common Challenges in Sequatchie Homes and How HEP Company Addresses Them

Sequatchie’s geographical location and housing stock present unique obstacles. HEP company’s experience ensures effective solutions that prevent future problems.

Mountainous Terrain and Elevation Changes

Uneven terrain can restrict airflow around outdoor units. HEP company installs elevated pads and specialized mounting brackets to promote proper ventilation and protect equipment from runoff.

High Humidity and Seasonal Rainfall

Excess moisture can rust components and foster microbial growth. Dehumidification add-ons and corrosion-resistant materials safeguard system longevity.

Older Homes with Limited Duct Space

Many Sequatchie properties feature tight crawl spaces or outdated duct designs. Technicians employ compact air handlers, ductless mini-split additions, or retrofit ductwork to fit space constraints without sacrificing comfort.

Power Outages and Voltage Fluctuations

Storms and rural grid limitations occasionally disrupt electricity supply. HEP company offers surge protection devices and recommends compatible backup power solutions to keep critical HVAC components safe.

Maintenance Tips After a New HVAC Unit Installation

A freshly installed HVAC system operates at peak performance when paired with diligent upkeep.

Essential Post-Installation Care

Replace or clean filters every one to three months.
Keep outdoor components free from leaves, grass clippings, and debris.
Inspect condensate drain lines for blockages and algae growth.
Schedule professional tune-ups twice annually—before summer and winter seasons.
Monitor thermostat settings to avoid excessive temperature swings.
Maintain clearance around indoor and outdoor units to enable proper airflow.
Record utility bills and note any significant changes in consumption as early warning signs of potential issues.

Sustainable Practices Followed by HEP Company

Environmental stewardship is integral to modern HVAC unit replacement. HEP company implements responsible practices throughout each project.

Green Initiatives

EPA-compliant refrigerant recovery and recycling prevent ozone depletion.
Proper disposal of old equipment in certified recycling facilities reduces landfill waste.
Recommendation of ENERGY STAR® qualified products limits greenhouse gas emissions.
Optimization of ductwork and sealing minimizes energy loss through leaks.

The Role of Proper Sizing and Load Calculation

Incorrectly sized HVAC systems can lead to short cycling, temperature inconsistencies, and premature wear. HEP company relies on industry-standard software and Manual J protocols to calculate heating and cooling loads.

Variables Considered

Local design temperatures for Sequatchie County
Insulation R-values of walls, ceilings, and floors
Window type, orientation, and shading characteristics
Number of occupants and internal heat gains from appliances
Infiltration rates based on building envelope tightness

Accurate sizing ensures that new equipment operates within manufacturer specifications, maximizing efficiency and lifespan.

Safety Standards and Codes Followed by HEP Company

HVAC unit replacement involves gas lines, high-voltage electricity, pressurized refrigerant, and combustion byproducts. HEP company upholds stringent safety measures to protect clients and technicians alike.

Safety Protocols

Adherence to International Mechanical Code (IMC) and local Sequatchie County building regulations
Proper combustion venting to prevent carbon monoxide accumulation
Use of calibrated instruments to verify gas pressure and airflow
Secure electrical connections with appropriate breakers and grounding
Consistent personal protective equipment (PPE) usage on job sites

Timeline Expectations for HVAC Unit Replacement Projects in Sequatchie

Project duration depends on system complexity, site conditions, and potential duct modifications; however, most residential replacements follow a predictable schedule.

Typical Sequence

Day 1: Assessment and load calculation
Day 2–3: Equipment procurement and staging
Day 4: Removal of old system and installation of new components
Day 5: Commissioning, performance testing, and client orientation

HEP company coordinates each phase efficiently to minimize downtime and disruption.

Insulation and Ductwork Upgrades That Complement a New HVAC Unit

To unlock the full potential of a high-efficiency system, a well-sealed building envelope and optimized ductwork are essential.

Recommended Enhancements

Attic Insulation Top-Off: Increasing R-value mitigates heat transfer through the roof structure.
Duct Sealing with Mastic or Aeroseal Technology: Prevents conditioned air loss into unconditioned spaces.
Insulated Duct Sleeves: Maintain consistent supply air temperatures in crawl spaces or attics.
