Our Educational Approach to Changeouts
The goal of heating and air conditioning is comfort. In a humid climate with a wide range of weather extremes, Raleigh, North Carolina presents unique challenges for HVAC. Education is key to ensuring your home is as comfortable as possible.
For HVAC installations and changeouts, it is important for us to hear your heating and air conditioning challenges, and work with you to develop solutions to maximize the value of your investment, your home’s comfort level, and your home’s energy efficiency. If you are shopping for a new unit, we will help you understand:
- The Importance of Proper Load Calculation: Load calculation is the measure by which we determine the size of your new unit. It is a myth that oversizing an HVAC system increases efficiency. An oversized unit will short-cycle, engaging and disengaging more often than it should, which decreases its efficiency and shortens its lifespan. In contrast, an undersized unit will run more often than it should, which ultimately shortens its lifespan and increases your energy costs.
- The Benefits of Multi-Stage HVAC: As opposed to traditional units that run at full capacity whenever they are engaged, multi-stage heating and air conditioning systems are capable of running at lower capacities when demand is lower. Especially in Spring and Autumn, when temperatures are mild, owners of multi-stage HVAC systems see significant savings in energy costs.
- The Intricacies of Proper Thermostat Placement: It matters where your thermostat is placed. If your thermostat is in direct sunlight for a portion of the day, near a supply or return vent, or near large electronics (television, desktop computer, etc.), your home may be unnecessarily uncomfortable and your HVAC system’s longevity may be threatened. Irregular temperature fluctuations near your thermostat may cause your system to short-cycle, which hurts your unit’s energy efficiency and lifespan.
- The Benefits of Effective System Design: Proper airflow is vital to indoor air comfort. In order to design the most efficient and effective duct work system, we utilize state-of-the-art software that calculates the airflow CFM (cubic foot per minute) necessary to maximize your home’s comfort level. By calculating the CFM in each room, we can customize duct work and supply and return vents to maximize your system’s airflow.
- The Necessity of Regular and Proper HVAC Maintenance: Regular and proper HVAC maintenance will help lengthen the life of your system.
Regular Maintenance and Maintenance Agreements
Your heating and air conditioning system operates approximately 3,300 hours per year. If you drove your vehicle 3,300 hours per year, at 65 miles per hour, you would travel about 215,000 miles. You could not drive so many miles without changing the oil, replacing the brake pads, rotating the tires, etc. Similarly, your HVAC systems requires basic, routine maintenance. For example:
- Regularly (monthly) checking and changing the air filters
- Maintaining proper clearance around the outdoor unit and indoor vents
- Inspecting refrigerant lines for leaks
- Measuring the temperature of your supply and return vents (when the air conditioning is engaged air supplied should be about 20 degrees cooler than the temperature of the room).
- Inspecting the base pan, coil, fan motor, etc. for damage
All American Maintenance Agreements are a valuable alternative to homeowners performing their own maintenance. Maintenance Agreements ensure your unit is running at its peak efficiency and will last as long as possible. Additionally, all Maintenance Agreements include:
- Two Precision Tune Ups
- New Air Filters
- Priority Customer Service
- Discounts for Parts and Labor
- Refrigerant Pressure Tests
- Drain Line Cleanings
Your comfort is our goal. By improving energy efficiency through routine maintenance, homeowners can recuperate the cost of maintenance agreements in monthly energy savings. Additionally, expert HVAC installation and regular maintenance will maximize your home’s comfort level for the life of your system.
