Why professional HVAC installation matters in Westerville
Westerville experiences humid, hot summers and cold winters, so your heating and cooling system must be matched to both the climate and the specific characteristics of your house. An undersized unit will run constantly and struggle to dehumidify in July. An oversized unit will short cycle, creating temperature swings and excess wear. Poorly installed ductwork or refrigerant charge can negate efficiency gains from even the best equipment. Best Service Heating & Cooling applies industry-standard sizing and installation practices tailored to central Ohio weather and Westerville building standards to avoid these pitfalls.
Common HVAC needs we address in Westerville homes
- Replacement of aging furnaces or air conditioners that no longer meet efficiency or reliability expectations
- Converting older systems to high-efficiency units to reduce energy costs during hot, humid summers and below-freezing winter nights
- Installing heat pumps or ductless systems in additions, garages converted to living space, or older homes without ductwork
- Upsizing or redesigning duct systems in renovated Westerville homes to improve airflow and comfort
- Replacing mismatched split systems where indoor and outdoor units are not properly paired
- Bringing systems up to current city of Westerville and state code, including permits and inspections
System options we install
We install and commission a full range of HVAC equipment, selected to fit your home and comfort goals:
- Furnaces: high-efficiency gas and electric furnaces sized by load calculation for consistent winter comfort
- Air conditioners: central AC and packaged systems with SEER ratings appropriate for Ohio summers
- Heat pumps: air-source and hybrid systems that provide both efficient heating and cooling through shoulder seasons
- Ductless mini-splits: zoned comfort solutions for additions, sunrooms, or homes without ductwork
- Multi-zone systems and zoning components for improved comfort control across multiple living areas
- Ventilation and indoor air quality components that integrate with new systems
Best Service Heating & Cooling focuses on matching the right equipment to your home, not selling the most expensive option. That match is determined through careful evaluation, not guesswork.
How we determine the right system: Accurate load calculations and diagnostics
The first step in any responsible HVAC installation is a detailed load calculation. We use Manual J load analysis to determine the heating and cooling requirement for each living space in your home. That calculation considers:
- Square footage and room-by-room layout
- Insulation levels in walls and attic
- Window types, orientation, and shading (important in Westerville neighborhoods with mature tree cover)
- Air infiltration estimates and recent weatherization work
- Number of occupants and typical internal heat gains
After the load calculation, we perform a Manual S equipment selection to choose the proper model based on efficiency, capacity, and expected operating conditions. If ductwork is present, a Manual D duct analysis is used to verify the system will deliver correct airflow. If ductwork is inadequate, we will outline necessary repairs or redesigns so the new equipment can operate at peak efficiency.

- Mechanical clearances and service access requirements
- Sealing and insulation requirements that impact energy code compliance
Working with a contractor who understands Westerville regulations reduces delays and ensures long-term safety and code compliance for your home.
Post-installation testing and commissioning
A new HVAC system must be tested under real operating conditions to verify performance. Our commissioning checklist includes:
- Verifying duct static pressure and supply/return airflow meets design values
- Checking refrigerant pressures and temperatures, and adjusting charge as needed
- Measuring temperature split across the evaporator to confirm efficient cooling
- Confirming proper operation of safety devices and controls

Energy efficiency and long-term savings — what to expect
Upgrading to modern, high-efficiency equipment typically reduces monthly energy consumption and improves comfort. Depending on the existing system and the chosen replacement, homeowners in Westerville can expect:
- Lower energy usage during long cooling seasons thanks to higher SEER-rated air conditioners
- Reduced natural gas consumption with high AFUE furnaces or hybrid heat pump solutions
- Better humidity control in summer months, improving perceived comfort while lowering thermostat setpoints
- Extended equipment life and fewer repairs with proper installation and routine maintenance
Accurate load sizing combined with well-executed ductwork and commissioning is fundamental to achieving these savings. A high-efficiency label alone does not guarantee results without professional installation.
Common problems a new installation resolves
A properly designed and installed HVAC system addresses many frequent comfort complaints seen in Westerville homes:
- Uneven heating and cooling between floors or rooms
- Short cycling of older units that leads to high utility bills and poor humidity control
- Noisy systems caused by undersized or poorly supported equipment
- Increased allergy and dust issues linked to leaky, dirty ductwork
- Systems that struggle in extreme temperatures due to incorrect sizing or refrigerant charge
By diagnosing the root cause and designing the system around your home, Best Service Heating & Cooling eliminates recurring issues rather than masking symptoms.
Considerations for older homes and historic Westerville neighborhoods
Many Westerville properties have older construction details, multiple additions, or limited mechanical spaces. These factors require thoughtful planning:
- Space constraints may necessitate compact units, ductless options, or creative layout adjustments
- Historic homes often have original ductwork or no ducts at all; ductless mini-splits or high-velocity systems can be practical alternatives
