HVAC Glossary
- SEER (Seasonal Energy Efficiency Ratio): Measures cooling efficiency. Higher SEER = lower energy bills.
- HSPF (Heating Seasonal Performance Factor): Measures heating efficiency for heat pumps. Higher HSPF = better energy savings in winter.
- AFUE (Annual Fuel Utilization Efficiency): Indicates how efficiently a furnace converts fuel to heat. Higher AFUE = less wasted energy.
- Zoning: Allows different areas (zones) of your home to be heated or cooled independently. Great for multi-level homes or rooms with different comfort needs.
- Smart Thermostat: Wi-Fi enabled thermostat that can learn your habits and be controlled remotely for added convenience and energy savings.
- Tonnage: Refers to the cooling capacity of an AC system. One ton = ability to cool 12,000 BTUs per hour. Sizing your system correctly in tons is critical for efficiency and comfort.
- BTU (British Thermal Unit): A measure of energy. Used to describe how much heating or cooling a system can provide.
- Load Calculation (Manual J): A professional assessment that determines the exact heating and cooling needs of your home based on size, layout, insulation, and other factors.
- Heat Pump: A system that provides both heating and cooling by transferring heat, rather than generating it. Heat pumps are ideal for Arizona’s mild winters and hot summers.
- Indoor Air Quality (IAQ): Refers to the quality of air inside your home. IAQ solutions like air purifiers and upgraded filters can reduce allergens and improve health.
- Energy Star® Rated: Products certified by the EPA to meet strict energy efficiency guidelines. Often eligible for rebates and can reduce utility costs.
Step 1: Evaluate Your Climate and Home’s Needs
Every home is different, and so is every climate. Living in Arizona, we know that our hot summers and mild winters require cooling power we can count on, along with heating that doesn’t break the bank during those cooler months. The Gilbert area is no stranger to summers over 110+ degrees and winter lows dipping close to freezing. That means dependable system are essential.
Next, consider your home’s size, layout, and insulation. Larger homes or those with multiple stories may need more powerful systems or even zoning options to maintain consistent comfort. Home layout matters too — a sprawling single-story home may need different air distribution than a compact two-story home.
- 1,000–1,500 sq. ft. – Typically needs a 2–2.5 ton system
- 1,500–2,000 sq. ft. – Typically needs a 3–3.5 ton system
- 2,000–2,500 sq. ft. – Typically needs a 4–5 ton system
Step 2: Assess Your Current Setup
To make the most informed decision, start with a quick evaluation of your current system and home setup:
- Insulation Check: Poor insulation leads to energy loss and overworked systems.
- Windows and Doors: Drafty windows and doors allow conditioned air to escape. Seal any leaks for better efficiency.
- Current System Performance: Is your current system meeting your needs? How old is it? Frequent repairs or inconsistent comfort may signal it’s time for an upgrade.
- Energy Bills: A steady rise in your utility bills often means your system is losing efficiency.
- Ductwork Condition: Leaky or poorly sized ducts can drastically reduce system performance. If possible, have your ducts inspected.
Avoid These Common Mistakes When Choosing an HVAC System
- Skipping a Professional Load Calculation: Relying on rough estimates or your current system size can lead to inefficiency. That’s why our team uses a Manual J Load Calculation to make sure the perfect fit for your home.
- Choosing the Wrong Size: A system that’s too large will cycle on and off too frequently, reducing efficiency and lifespan. Too small, and it won’t keep you comfortable.
- Ignoring Ductwork: Old, leaky, or poorly designed ductwork can reduce your new system’s performance by up to 30%.
- Overlooking Future Needs: Planning a remodel or addition? Choose a system that can adapt to future changes.
What Is a Load Calculation and Why Does It Matter?
A Manual J Load Calculation is an industry-standard method for determining exactly how much heating or cooling your home needs. It takes into account:
- Square footage
- Window types and placement
- Insulation levels
- Sun exposure
- Number of occupants
By performing this calculation, we make sure your system isn’t over- or under-sized, both of which can lead to higher energy bills and wear on your system. Our team offers load calculations as part of our consultation process to help you make the best choice for long-term comfort and efficiency.
With these details in hand, you’re ready to choose a system that fits your home and comfort needs perfectly.
Now that you have a better idea of what your home needs, let’s explore the different types of HVAC systems and how they might work for you.
Step 3: Know Your Options – Choose the Right Type of HVAC System
Choosing the right HVAC system starts with knowing your options. Let’s take a look at the most common types of systems, their benefits, and how to determine which one fits your home best.
Central Air Conditioners
Central AC systems are widely used in Arizona homes, particularly those with existing ductwork. These systems deliver consistent, whole-home cooling and pair well with programmable thermostats and zoning configurations to help maintain stable indoor temperatures even during peak summer heat. Because of their ability to distribute cool air evenly throughout multiple rooms, they remain a practical solution for larger or multi-level homes.
- Pros: Provides uniform cooling, integrates with existing duct systems, and supports energy-saving features like smart thermostats.
- Cons: Installation costs can be higher if ductwork is outdated; may be less efficient for smaller spaces or single-room use.
- Best For: Homes already equipped with ducts, especially those with multiple rooms or floors.
- Maintenance Needs: Includes seasonal inspections, regular air filter changes, and periodic duct services to maintain efficiency and air quality.
- Typical Lifespan: AC replacement is typically needed after 12–15 years, depending on usage and maintenance routines.
A well-maintained central AC system can keep your home comfortable and efficient through even the hottest Arizona summers! For homeowners who also want efficient heating along with cooling, a heat pump might offer more year-round value—especially in the areas mild winter climate.
Heat Pumps
Heat pumps have become a popular choice in the Valley thanks to their ability to efficiently handle both heating and cooling needs in one system. Instead of generating heat, they transfer it, making them especially energy-efficient and well-suited for our area’s mild winters and long, hot summers.
- Pros: Provides energy-efficient heating and cooling in one system.
- Cons: Can be less efficient in freezing conditions, though this rarely affects homes in the Valley.
- Best For: Homeowners looking for a dual-purpose system that performs well in warm or temperate climates.
- Maintenance Needs: Recommends biannual maintenance—typically before the cooling and heating seasons—and regular air filter replacements.
- Typical Lifespan: 10–15 years with consistent maintenance and proper usage.
For added flexibility, some homeowners pair a heat pump with an electric furnace for supplemental heating during cooler months. This setup helps maintain comfort and efficiency, especially when weighing different factors, such as system performance, energy use, and long-term costs in our unique climate.
Electric Furnaces
In our climate, electric furnaces are rarely used on their own. Instead, they’re typically paired with a central air conditioner or serve as a backup heat source to a heat pump system. These electric units provide reliable, low-maintenance heating and are known for their compact design and clean, electric operation — ideal for homeowners who want to avoid gas or oil.
- Pros: Affordable installation, no risk of carbon monoxide, compact size, and easy to integrate with existing AC or heat pump systems.
- Cons: Higher energy usage than heat pumps for heating, which may increase operating costs if used frequently.
- Best For: Homes with central AC needing a dedicated heating source, or as a heat supplement in systems with heat pumps.
- Maintenance Needs: Annual inspections, air filter replacements, and occasional cleaning of internal components to maintain performance.
- Typical Lifespan: 15–20 years until furnace replacement is needed with proper care and moderate usage.
While oil furnaces are less common in the Valley, some homeowners still compare oil and electric for heating performance. However, if you’re looking for a versatile system that offers both heating and cooling without the need for ducts, there’s another option worth considering.
Ductless Mini-Splits
No ducts? No problem. Ductless mini-splits are perfect for adding comfort to specific areas, like garages, sunrooms, or additions, without the need for major renovations.
- Pros: No ductwork needed, zoning control for individual rooms, highly energy-efficient.
- Cons: Higher upfront cost per unit; may not be ideal for very large spaces.
- Best For: Homes without existing ducts, garages, add-ons, or individual room control.
- Maintenance Needs: Regular filter cleaning, annual servicing for refrigerant and system checks.
- Typical Lifespan: 12–20 years with proper maintenance.
Integrating ductless mini-splits with existing HVAC systems can enhance home comfort, especially in areas that are difficult to cool or heat evenly. In fact, combining the two can improve energy efficiency and provide greater control over specific zones of the home without requiring major modifications to existing infrastructure.
Air Handlers
An air handler is responsible for circulating conditioned air throughout your home, helping your HVAC system run more efficiently and maintain even temperatures in every room. It’s commonly paired with heat pumps or central air conditioners and is especially important in larger homes or multi-level properties where consistent airflow is key.
- Pros: Enhances system efficiency, helps maintain consistent indoor temperatures.
- Cons: Needs to be matched correctly with your HVAC system.
- Best For: Homes using heat pumps or central AC systems.
- Maintenance Needs: Filter changes, coil cleaning, blower inspection.
- Typical Lifespan: 10–15 years.
So, what do air handlers actually do? Beyond moving air, they help regulate humidity, support air quality, and ensure your HVAC system isn’t working harder than it needs to. With a clearer understanding of your system options, the next step is narrowing down what features and priorities will make the biggest difference for your home and comfort.
Step 4: Prioritize What Matters to You
Now that you know your options, it’s time to think about what really matters to you in a system. Here are a few other key factors that can help you make your final decision.
Efficiency Ratings
When shopping for HVAC systems, look at efficiency ratings like SEER (check out our SEER calculator!) for cooling and HSPF (Heating Seasonal Performance Factor) for heating. Higher ratings usually mean lower energy bills.
Budget and Long-Term Value
While some systems may have a higher upfront cost, they could save you money over time with lower operating costs. Think about your long-term comfort and utility bills, not just the initial price tag.
Smart Features and Zoning
Modern systems often come with smart thermostats, remote control features, and zoning capabilities. These can help you customize your comfort and cut down on energy use.
