🌡️ HVAC Systems Explained: What’s Best for Your Home

🧱 Introduction

When it comes to home comfort, few systems matter more than your HVAC (Heating, Ventilation, and Air Conditioning) system. It controls your indoor temperature, air quality, and energy efficiency year-round.

But with so many options — from traditional split systems to ductless mini-splits — choosing the right HVAC setup can feel overwhelming.

At Nail & Hammer Construction Corp, we help Los Angeles homeowners select, install, and maintain the best HVAC solutions for their space, climate, and budget. Here’s what you need to know before making your next investment.

❄️ Split Systems, Mini-Splits, and Central Air Options

Understanding the main types of HVAC systems helps you match performance with your home’s design and comfort goals.

🔹 Split System (Traditional Central Air)

The most common setup for single-family homes, featuring an outdoor condenser and an indoor air handler connected by refrigerant lines.

Pros:

• Consistent cooling and heating through ductwork

• Can pair with gas or electric furnaces

• Works well for medium to large homes

Cons:

• Requires existing ductwork

• Can lose energy through leaky ducts

💡 Best For: Homes with existing ducts and traditional layouts.

🔹 Ductless Mini-Split Systems

Mini-splits offer zoned comfort with individual air handlers installed in each room — no ducts required.

Pros:

• High efficiency and quiet operation

• Zoned temperature control (cool one room, save energy in others)

• Ideal for additions, garages, and ADUs

Cons:

• Higher upfront cost per unit

• Wall-mounted units may not fit every aesthetic

💡 Best For: Homes without ductwork or with remodels/ADUs needing flexible temperature zones.

🔹 Packaged or All-in-One Systems

Everything — compressor, coils, and air handler — is housed in one outdoor unit.

Pros:

• Compact design, great for small homes or rooftops

• Simplifies maintenance

Cons:

• Less efficient than split or ductless systems

• Shorter lifespan in harsh outdoor conditions

💡 Best For: Small homes or multi-family units with limited indoor space.

⚙️ How Tonnage and SEER Ratings Affect Performance

🔹 HVAC Tonnage Explained

“Tonnage” doesn’t refer to the system’s weight — it measures cooling capacity.

• 1 ton = 12,000 BTUs per hour

• Most homes range from 2–5 tons, depending on square footage, insulation, and exposure to sunlight.

💡 Pro Tip: Oversized systems short-cycle (turn on/off too quickly), while undersized systems run constantly — both waste energy and shorten equipment life.

🔹 SEER Ratings (Seasonal Energy Efficiency Ratio)

The SEER rating measures how efficiently an AC or heat pump cools over an average season.

• Older units: SEER 10–13

• Modern minimum (California): SEER 15–16

• High-efficiency systems: SEER 20+

Higher SEER = lower utility bills and reduced carbon footprint.

💡 Pro Tip: For Los Angeles’ mild climate, a 16–18 SEER system often offers the best balance of performance and cost.

🌿 Energy-Saving Upgrades and Maintenance

Regular maintenance and small upgrades can greatly extend your HVAC system’s lifespan and reduce energy use.

🧰 Smart HVAC Upgrades:

1. Programmable or Smart Thermostats

   • Adjust temperatures automatically for daily routines.

   • Integrate with Alexa or Google Home.

2. High-Efficiency Air Filters

   • Improve air quality and reduce system strain.

3. Zoned Dampers or Smart Vents

   • Control airflow to specific rooms, saving energy.

4. Duct Sealing & Insulation

   • Prevent air leaks that can waste up to 30% of system output.

5. Annual Tune-Ups

   • Clean coils, test refrigerant, and check airflow for peak performance.

💡 Pro Tip: Combine HVAC upgrades with solar power or battery backup systems to create a sustainable, low-cost energy ecosystem.
