Is your HVAC unit summer ready?

With summer on the horizon, it’s a good time to ask: Is your HVAC unit summer-ready? HVAC, which stands for Heating, Ventilation, and Air Conditioning, refers to a complete home comfort system that keeps you cool in the summer and warm in the winter, while also improving indoor air quality.

Before the heat arrives in full force, it’s a smart idea to check on your HVAC’s readiness. If you’re not sure if your system is ready to face the heat, don’t worry – we’ll break down the key steps to get it summer-ready and explore the different types of HVAC systems available

Is your HVAC unit summer ready?

Before we explore ways to ensure your HVAC unit is summer-ready, let’s understand what an HVAC system is. Think of it as your home’s climate control system, working together to keep you comfortable year-round. The heating part keeps you warm in winter, ventilation brings in fresh air, and air conditioning (AC) cools you down in summer. Now that you know what an HVAC is, here are some easy ways to ensure yours is ready for the summer:

1. Yearly checkups: Schedule a professional inspection by an HVAC technician at least once a year. They’ll examine the entire system, identify any potential issues, and make sure everything is running smoothly for peak summer performance.

2. Air filter replacement: The air filter is sort of like the lungs of your HVAC system, trapping dust and allergens to keep your air fresh. A clean filter also allows the system to function efficiently. To maximize airflow and avoid problems during hot summer months, be sure to check the filter monthly and replace it as and when needed.

3. Clean the outdoor unit: The outdoor condenser unit is the part that removes heat from your home. Over time, dirt can accumulate, leading to reduced airflow. A blocked condenser forces the unit to work harder, thus leading to inefficiency. To ensure proper airflow, clear away any clutter from around the unit regularly.

4. Seal leaks: Tiny cracks and air leaks around windows and doors can force your HVAC to work extra hard. Take some time to seal any leaks you find. This will help keep cool air inside and hot air outside.

5. Block the sun: South-facing windows get hit by the sun the most. Consider adding shade, blinds, or window tinting to deflect sunlight and keep your home cooler naturally. This will also reduce the workload on your HVAC system.

Types of HVAC systems

With your HVAC prepped for summer, let’s dive into the common types of HVAC systems available in the market:

1. Split systems (central air conditioning and furnace)

This is the most popular choice, consisting of two separate units: an outdoor air conditioner and an indoor furnace. The outdoor unit cools air with refrigerant, and the furnace distributes cool or heated air through ducts throughout your house. Furnaces typically use natural gas or oil to generate heat, making them effective for most climates. However, they might struggle in areas with extremely cold winters.

2. Heat pumps

These act like a two-in-one system, providing both heating and cooling. In the summer, they work like an air conditioner, pulling heat out of your home. In the winter, they reverse the process, extracting heat from the outside air and pumping it inside to warm your space. Heat pumps are very efficient, especially in moderate climates where it doesn’t have to work as hard in the winter.

3. Ductless mini-splits

These systems are ideal for single rooms since they don’t require ductwork. This not only eliminates energy loss from ducts but also simplifies overall installation. Ductless mini-split systems consist of a wall-mounted indoor unit and an outdoor compressor. Each indoor unit can be controlled independently with individual remote controls, allowing for customized comfort in different zones.

4. Geothermal heat pumps

The ultimate in energy efficiency, geothermal HVAC systems harness the constant temperature of the earth (geothermal energy) to heat and cool your home. A network of pipes buried underground transfers heat to or from the earth depending on the season. While the initial installation requires a larger investment, geothermal systems become very cost-effective in the long run.

5. Other types of HVAC systems

i. Packaged systems: These combine the heating and cooling units into a single, compact outdoor unit and are often used in smaller homes.

ii. Hydronic heating systems: These use hot water instead of air to distribute heat throughout your house. Baseboard heaters or radiant floor heating are common examples.

iii. Portable AC units and space heaters: While not ideal for whole-house comfort, these can be temporary solutions for spot cooling or heating-specific areas.

Ultimately, choosing the right HVAC system depends on your climate, home size, budget, and individual needs. If you have one already, make sure to check up on your HVAC unit from time to time to prevent costly repairs and ensure optimal performance.
