What our customers say

We have much experience with HEP HVAC service and we have been beyond thrilled! We have just recently replaced our 5 ton heating and air unit and HEP installed a TRANE unit at a very fair price with spectacular warranties! Our old humidification system had a problem that was discovered during the new install and there was mold in our humidifier lines. The HEP installers removed all the moldy tubing and cleaned and removed everything. Even adding some insulation where the old humidifier was attached. This was going way beyond the call of the job. It was doing RIGHT even when nobody was looking. We were alerted to the concern and we fixed it together! Sure we pay for the service but it feels more like teamwork than just purchasing an item. HEP is on our family TEAM! Thank you HEP for doing right (making things right) even if it makes the job more difficult at the time. You all seem to keep your eyes on the long term good of your customer.

Tami B.

A fast and quick diagnosis of our HVAC problems and very helpful.

I had hep come out and do service on my unit. The tech was very knowledgeable in what he does and explained what was going on with my unit.

Nathan S.

John Smith did a wonderful job! He came out and did an efficient and thorough job checking out our unit.

Makaylia B.

Had HEP do heat and air system maintenance on 2 units at my house yesterday. The technician showed up when he said he would and seemed very knowledgeable and thorough. I would definitely use HEP again!

Rodger M.

We paid for HEP's Preventative Maintenance Agreement when selling a deceased family member's home and we then transferred the agreement to our home once the house was sold. We just received our first HVAC inspection and Ben Ferguson was our technician. He provided excellent service and advice for our aging units and I felt that he had our best interest in mind versus maximizing profit for the company by suggesting unneeded repairs for items that will be obsolete in a view years time. I can assure you that this long term view of retaining customers through honesty and integrity will be much more profitable compared to a short-term repair that we may or may not need. Ben was professional, thorough, and answered any questions that I had throughout the process. HEP should be proud to have him as an employee and I hope they see him as a valued team member. Service order 092004 on 07/29/15.

Alton W.

Our original call to Hep was a year ago when our air conditioner wasn't cooling properly. It was also on a weekend when it is difficult to get a repairman to even talk with. We called Hep, and they made an appointment with us immediately. They showed up as scheduled and had our problem fixed very quickly. The most recent visit was last week when they came for a routine yearly check up. They called ahead and set up the appointment, then they showed up as scheduled. Very good service, and I would highly recommend them to others!

Comprehensive Heating, Ventilation, and Air Quality Solutions in Blountville

Blountville’s four‐season climate demands robust, reliable heating and cooling systems—but comfort involves more than simply adjusting the thermostat. Clean indoor air, balanced humidity, and efficient airflow all contribute to a healthier living environment. HEP specializes in heating, air conditioning, ventilation, and air quality services tailored to the unique needs of homes and businesses across Blountville.

Why Indoor Air Quality Matters in Blountville’s Climate

Blountville experiences hot, humid summers and chilly, damp winters. These fluctuations can elevate indoor pollutant levels, encourage mold growth, and strain HVAC systems if ventilation is inadequate. The region’s pollen counts and occasional temperature inversions further trap airborne contaminants indoors. Quality ventilation combined with targeted air purification combats:

Allergens such as ragweed, pollen, and dust mites
Mold spores nurtured by high humidity
Volatile organic compounds (VOCs) emitted by paints, flooring, and household cleaners
Excess carbon dioxide and stale air in tightly sealed modern homes

Improving indoor air quality (IAQ) reduces respiratory irritation, supports restful sleep, and helps HVAC equipment operate efficiently year‐round.

Key Components of HEP’s Ventilation and Air Quality Services

Comprehensive air quality assessments
Mechanical ventilation system design
Advanced air filtration and purification installation
Humidity management through dehumidifiers and humidifiers
Ductwork inspection, cleaning, and sealing
Ongoing maintenance plans for sustained performance

Each component works in unison, ensuring that heated or cooled air circulates freely, remains contaminant‐free, and maintains ideal moisture levels.

Detailed Look at HEP’s Ventilation Approach

Modern construction practices often create airtight building envelopes. While energy losses decrease, natural air exchange diminishes dramatically. HEP counteracts this by integrating mechanical ventilation systems engineered for Blountville’s seasonal swings.

Mechanical Ventilation Explained

Mechanical ventilation actively introduces fresh outdoor air while exhausting stale indoor air. Systems range from simple exhaust fans to energy recovery ventilators (ERVs) and heat recovery ventilators (HRVs). These solutions balance indoor pressure, dilute pollutants, and recover energy otherwise lost.

Benefits of Professionally Designed Ventilation

Consistent delivery of fresh air without sacrificing energy efficiency
Reduced indoor humidity in summer months
Enhanced furnace and air conditioner longevity thanks to optimized airflow
Lower pollutant concentrations for improved occupant health

Typical Ventilation Equipment HEP Installs

Kitchen and bathroom exhaust fans with low‐sone ratings for quiet operation
HRVs that reclaim heat from outgoing air during cooler months
ERVs for simultaneous heat and moisture exchange in humid summer conditions
Whole‐house balanced ventilation systems tied into existing ductwork

Air Filtration and Purification Strategies

Ventilation alone cannot neutralize every contaminant. Filtration and purification form the second line of defense against microscopic particles and microbial threats.

Filtration Options

Standard pleated filters for everyday dust control
High‐efficiency media filters capturing smaller particulates, including pollen and pet dander
HEPA‐level filtration integrated within dedicated air cleaners

Purification Technologies

Ultraviolet germicidal irradiation (UVGI) lamps to inactivate bacteria, viruses, and mold spores
Photocatalytic oxidation (PCO) units targeting VOCs and odors
Ionization systems that cause particles to clump and fall from the breathing zone

Selecting the Right Combination

HEP technicians evaluate property size, existing HVAC capacity, occupant sensitivities, and budget to tailor filtration and purification solutions. The goal is a balanced system that traps physical particles while neutralizing biological and chemical contaminants without restricting airflow.

Humidity Control: Balancing Moisture for Comfort and Health

Blountville’s hot summers invite excessive indoor humidity, while winter’s dry air can irritate skin and sinuses. HEP implements precise moisture control via:

Whole‐home dehumidifiers removing latent heat and moisture during muggy months
Bypass or fan‐powered humidifiers reintroducing moisture when heat sources dry the air
Smart controllers monitoring relative humidity and adjusting equipment automatically

Balanced humidity:

Inhibits mold and dust mite populations
Preserves wooden furniture and flooring
Reduces static electricity
Enhances overall comfort at lower temperatures, saving on heating costs

The Role of Ductwork in Air Quality

Even a high‐efficiency HVAC system falters if ductwork leaks, harbors debris, or remains improperly sized.

Duct Inspection and Testing

HEP employs video scopes and pressure testing to locate:

Loose or disconnected joints
Dirt accumulation and microbial growth
Crushed, kinked, or undersized sections restricting airflow

Duct Cleaning

Specialized agitation brushes and high‐capacity vacuums remove years of dust, pet hair, and construction debris lodged within duct walls. Sanitizing agents neutralize mold and bacteria after cleaning.

Duct Sealing and Insulation

Mastic sealant or aerosolized polymer coatings close gaps, preventing conditioned air from escaping into unconditioned spaces. Proper insulation maintains temperature as air travels through attics or crawlspaces.

Energy Efficiency and System Performance

Quality ventilation and air purification do not have to inflate utility bills. Correctly sized equipment, smart controls, and recovery mechanisms ensure minimal energy waste.

Energy Recovery Ventilators (ERVs)

ERVs transfer both heat and moisture between intake and exhaust streams. During summer, humid outdoor air relinquishes moisture to cooler, drier exhaust air, safeguarding indoor comfort while trimming dehumidification load on the air conditioner.

Heat Recovery Ventilators (HRVs)

HRVs excel in cold weather, reclaiming thermal energy from outgoing air to pre‐warm incoming fresh air. Furnaces cycle less often, saving fuel and extending equipment life.

Efficient Fan Motors and Controls

Electronically commutated motors (ECMs) adjust fan speed dynamically for optimal airflow
Demand‐controlled ventilation based on CO₂ sensors ventilates only when needed
Programmable thermostats integrate with humidity sensors for holistic climate management

Common Indoor Air Issues Resolved by HEP

Allergy and Asthma Triggers

High‐efficiency filters and UV lamps remove airborne allergens, providing relief to sensitive occupants.

Persistent Odors

PCO and activated carbon layers neutralize smoke, cooking, and pet odors at a molecular level.

Visible Dust Accumulation

Leaky ducts and undersized filters often contribute to dust buildup on surfaces. Sealing ducts and upgrading filtration reduce housekeeping burdens.

Condensation on Windows

Excess humidity frequently condenses on cool glass panes. Balanced ventilation with ERVs and dehumidifiers addresses moisture before it becomes a problem.

Seasonal Maintenance Tailored for Blountville Residents

Regular tune‐ups help equipment perform flawlessly despite rapid temperature shifts between seasons.

Spring and Summer Checklist

Inspect refrigerant charge and coil cleanliness
