What You Need to Know Before Buying an In-Wall Air Conditioner and Heater

If you are in the market for a new air conditioner and heater, you may be considering an in-wall unit. These units have many benefits, including taking up less space than traditional window units and being more energy efficient. However, there are a few things you need to know before making your purchase.

In this blog post, we will discuss the key factors you need to consider when shopping for an in-wall air conditioner and heater.

1. Size:

Before buying an in-wall unit, make sure you measure the space where it will be installed. Most units come in standard sizes, so you’ll want to choose one that fits the dimensions of your wall or ceiling.

You also need to consider whether the unit is powerful enough to cool and heat efficiently for your particular size room.

2. Installation:

Installing an in-wall air conditioner and heater requires the services of a professional HVAC technician.

This is due to the complexity of installation, as well as any local regulations or codes that must be followed when installing such equipment. Make sure you factor this cost into your budget before making a purchase.

3. Efficiency:

In-wall air conditioners and heaters are designed to be more energy efficient than their window counterparts.

However, not all units are created equal in terms of efficiency – some have higher SEER ratings (Seasonal Energy Efficiency Ratio) than others.

Make sure you compare the energy costs associated with different models before making your final decision.

4. Noise Level:

Some in-wall air conditioners and heaters can be quite loud when running. This is something you should consider if your unit will be installed near bedrooms or other quiet areas. Consider models with lower decibel ratings for a more peaceful experience.

5. Maintenance:

Like all home appliances, regular maintenance is important for keeping your unit running at peak efficiency. This includes changing air filters, cleaning coils and fins, and inspecting drain pans.

Make sure you factor routine maintenance into your budget to keep your in-wall unit running properly.
