Why Would You Install a Window AC with Heat
Window air conditioners are intended to provide comfort during summer. After summer, most homeowners would not use them until the next season. When winter creeps in, you’ll need a space heater to provide the warmth. That means you’ll have two separate units for both summer and winter.
A window unit with heat is a good investment because it’s a two-unit in one. It will cool your room during the sweltering summer season and keep it warm during the cold winter. However, I’d recommend a window heat pump for people that experience moderate temperatures both in the summer in winter.
Here are other benefits of investing in a heating and cooling window unit.
This is the first major advantage that you get from window ac with heat – they’re both fairly expensive to purchase and operate every month.
While some units cost as low as $100, others would go as high as $2000. However, the average cost of a typical window unit for a medium room would cost $300 to $500.
That means it’s way low than what you’d spend on installing central air or ductless air conditioners that require over $1000 to purchase and install depending on the brand, BTU capacity, and the features associated with the device itself.
Ideal for Small Spaces
Even if you have a central cooling system installed, some rooms may not get the full benefit. They’ll always be hotter or colder than the rest of the house, no matter what you set your thermostat to.
Installing a window air conditioner with heater in these rooms can transform the rooms from being neglected during extreme temperatures to offering the perfect comfort all year round. Moreover, you’ll have few rooms to heat or cool using your primary heating and cooling system, reducing energy costs.
Easy to Install
Most window units are portable and easy to set up, even to a person with the least DIY skills. Manufacturers always include the installation materials and manuals to help you through the installation process.
After installation, you don’t have to worry about noise. These units operate quietly than most portable air conditioners or evaporative coolers that produce so much noise that conversation in the room.
Here is an easy DIY installation video that describes how to set up your AC in no time
Space heaters are one of the major causes of house fires. And no matter how cautious you are, the risks of using portable space heaters are still high. On the other hand, window air conditioners are much safer and don’t require constant monitoring, even if used in rooms with small children or pets.
Factors to Consider when Choosing a Window AC Unit with Heat
Before you go ahead with purchasing a window air conditioner, you need to keep certain things in mind. The most significant considerations include:
The primary and most obvious factor is the cost. You must have decided on a budget when you set out to buy an air conditioner, and your aim should be to determine the perfect balance between your budget and your cooling and heating needs. Since the price of air conditioners ranges from $100 to $2000, there are a lot of models to choose from based on price alone.
Low-cost appliances offer only basic features, and their heating and cooling capacities are comparatively low, making them suitable for smaller spaces.
On the other hand, high-end, expensive units come with plenty of features and additional functions. However, that doesn’t mean you should only go for them; you should realize that you can get more benefits if you spent a little more.
Besides the initial purchase, you have to take into account regular maintenance, and the associated energy costs. Air conditioners are major contributors to hefty energy bills. If you’re particularly concerned about getting an energy-efficient model, look for an Energy Star rated model.
Cooling and Heating Capacity
The size of your room determines cooling and heating capacity. Selecting the right unit requires you first to measure the space you want to install it in. Based on this measurement, you should search for a unit that is capable of serving that room.
For instance, if you’re looking for an air conditioner for a small room, a unit with a low BTU rating will suffice, but when it comes to cooling or heating larger rooms, high BTU units with more power will are necessary.
Convenience in Use and Maintenance
For many people, the convenience of using an air conditioner is among their top priorities. The more complicated the controls are, such as adjustment of the timer, thermostat, etc., the more problematic the unit will be.
While most air conditioners feature simple configurations, not all of them offer the full-function remote control option. If you wish to keep all the AC’s controls at your fingertips, look for the unit that can be fully programmed using a remote control.
Likewise, ease of maintenance and the associated costs are equally important. The costs and complications involved in cleaning an air conditioner vary from unit to unit. You now have the slide-out chassis feature in many air conditioners that makes cleaning super easy by making them more accessible.
You wouldn’t want to buy an affordable air conditioner that offers tremendous quality and performance, but malfunctions outrageously soon.
A heating and air conditioning window unit is indeed a massive investment, and if it can’t serve you in the long run, then that model isn’t worth buying. While there are slight variations in the lives of different units, the frequency of use, proper storage, and maintenance significantly impact their longevity.
Generally, air conditioners with the highest durability are those that come with extended warranties and after-care services. Certain models on the market are more reliable in terms of durability than others.
Another factor that determines the window unit you select is the type of your windows. There are different types of windows, but a typical window unit is usually installed in a double-hung window.
If you have casement, vertical, horizontal, or crank windows, then a casement or horizontal window air conditioner would be ideal for your room.
Electrical Requirements and Ease of Installation
The reason why electrical requirements should be carefully considered is that air conditioners require a higher amount of voltage than other household appliances.
Hence, the electrical system in your home should correspond with the power requirements of the unit you plan to install. In the case that the unit doesn’t get the power it needs, it will not function to its full potential, or even worse, its fuse may blow.
You’ll need to check the electrical requirements of the unit, such as the voltage, watts, and amps. The NEMA (National Electrical Manufacturers Association) classification and plug face type are other vital elements to check as well.
An air conditioner with a cooling capacity of 15,000 BTUs or above will require 220-volt, while those that have BTUs less than 15,000 can operate on 115 to 125-volt, the standard residential voltage. In the case of any confusion, seek help from an electrician.
Features of a Good Window Air Conditioner Heater Combo
If you’re going to spend a considerable amount of money on one of the best window air conditioners with heat, you need to get one that offers the most bang for your buck. Most modern window ACs provide extra features that simplify their use and maintenance. Check whether the unit you have chosen has these features or not:
While most window heating and cooling units come with a remote to control the functions, many of them have limitations in terms of the number of functions you may be able to control. Those offering full-function remote controls are the most convenient. Even if you don’t need full control, check whether the AC’s remote control includes temperature controls, timer adjustments, and selection of the operating model.
This feature helps you program your AC to maintain the precise temperature you want. Most people like their room temperature to reach and stay at a certain level. A programmable thermostat serves as a solution to this problem. As soon as the room temperature reaches your desired level, the AC senses this and stops heating or cooling the room.
While traditional air conditioners would require you to adjust the temperature through mechanical controls, most contemporary models come with a programmable feature that automates this function for you. Their digital display depicts actual and desired temperature readings for transparency. This not only makes the AC convenient but also helps you save energy as the AC will not be running all day long.
Energy Star Rating
As discussed earlier, energy bills are a major concern in the case of ACs. Buying an Energy Star rated AC is the best way to minimize how much you spend on your energy bill. This is because these units can are 10 to 30% more energy efficient than most other air conditioners.
Another tremendous feature to look for in a window ac with heater is the programmable timer. Through this feature, you can program your window AC to automatically switch on or off at specified times based on your schedule. With traditional ACs, you would have to arrive home and switch on your AC manually. Modern units feature a programmable timer that allows you to program the AC to switch on earlier so that you come home to an already cool room.
Automatic adjustments also help reduce energy costs as the unit will run only when required. This, with minimum interference, you can efficiently control your AC according to your requirements and save energy costs.
Adjustable Fan Speed
When cooling isn’t needed, you can use this feature to blow the cold air from the window air conditioner and heater combination unit or circulate air when cooling isn’t required. You can adjust the fan to varying speeds, depending upon how quickly you want to cool down your room. If your region experiences hot summers, switching to a higher speed will help cool your room quickly.
To sum up, this window air conditioner with heat reviews is intended to help you make an informed decision. Not all units are created equal, so it’s wise to find the best ac heater window unit that fits both your needs and budget.
Even when buying the best window air conditioner with heat, you still need to consider both the cooling and heating capacities. Check the size of the room the AC cools, and heater warms because it’s not always the same.
Besides checking the basic features, make sure you go through the additional features as well. If there’s a model that balances all your requirements, then that’s the one that you should go for.
