Let’s make a tough decision easy

Choosing your thermostat prompts a bunch of “what if” scenarios into your head. This is quite like being a new home owner that is understandably worried about their next purchasing decision. 

What if my RV is not compatible with my new thermostat, can I install it myself? What if it doesn’t fix my issue? Lets put most if not all of that to rest so we can get back to what matters, our comfort. 

This section will cover the common questions that we ask ourselves concerning RV thermostats.

Can you use any thermostat in an RV?

First things first, your traditional home thermostat will not just magically work in your RV. Most home thermostats run on 24V and RV thermostats run on a 12V power supply. 

That being said, it is very possible to get that same thermostat installed into your RV but for the sake of simplicity and ease-of-use, we will be focusing on thermostats specifically meant for RVs. Temperature in the RV will be controlled by your new upgrade so think of it as your access to comfort. 

Your air conditioner and RV temperature are so important for your comfort that when choosing a new thermostat, we need to keep in mind that there is a specific model that will cover the issue we might be having.

Types of Thermostats

Analog thermostats vs. Programmable digital thermostats is a great place to start . Analog thermostats are simple to use and cost-effective on the front end but they will cost you money down the line seeing as they aren’t very energy efficient. 

If your bills are running high and you suspect the thermostat to be the issue, consider a new thermostat as an investment that will pay itself off. While a programmable thermostat does offer a high level of convenience than other models, each holds their own merit. 

Not all digital thermostats are programmable either but they do provide more clear readings than analogs.

How do I know if my RV thermostat is bad?

Lets talk about some of the issues that cause us to make the switch to a new thermostat. Many of the positive user reviews that come with these four thermostats above can be reversed to the issue they were facing before the switch. Obviously comfort is the number one issue but let us delve deeper. 

Flexibility is another issue that directly ties in with programmable thermostats. The switch to a newer programmable models will provide you with a range of settings to meet your needs. 

Most older RV units are equipped with analog thermostats and for many, that controls temperature perfectly for them. If you do notice your air conditioner isn’t operating at the levels set by your thermostat, you have an issue. If the thermostat will not power on or the AC/heater wont turn on, there is an issue. 

Similarly if the unit runs constantly and never achieves the target temperature/won’t stop running for other reasons there are issues. One thing to keep in mind is that some of these issues can be beyond upgrading the thermostat.

Can I replace my thermostat myself?

We wish we could come install your thermostat for you but how about the next best thing? RV thermostat upgrade is not rocket science and so we should not treat it like so. While all four of these thermostats offer some unique value, the one factor they all share is an easy install. 

Each with their own guides online and plenty of community support to make this process as painless as possible. That being said if you do face any difficulties, check in with an expert from the respective company or an HVAC professional. 

Now to get a little technical and look back at what we talked about earlier, there are ways to make thermostats not meant for RVs into thermostats for RVs but this should be done by a professional who knows what they are doing. You do not want to cause harm to yourself or your RV air conditioner unit.

What is the best RV thermostat?

The best RV thermostat will be directly linked to your personal needs! We believe that certain products fit the needs of a wide variety of consumers. 

There is merit in the metrics of energy consumption when speaking on which RV thermostats to choose. Once all personal needs are met or even possibly before, energy consumption should be taken into consideration. Which do your prefer? 

A battery powered system or hard-wired? Extra wires is sure to have an impact on the install time and provide complications especially if there is a compatibility issue. 

Picking an upgrade that will save you more than the current model you are using is part of the appeal and we understand that price is a factor in this buying process. More popular among users is a programmable RV thermostat so you can set it and forget it as they say! 

Most of all, we want something that is user-friendly and works to our specific comfort needs. We checked many indicators while researching these thermostats but we always refer back to “the big four“. How easy is it to install? 

How easy is it to operate? How accurate is it? And last but not least, how durable is it? Let’s take a look at these upgrades and figure out which best suits your specific needs.

Does the unit control heat and air?

Most smart thermostats for RV control both heat and air. However, some cheap models will control only heat. Carefully check the device specifications before buying to ensure that it offers both hear and air conditioning control.

Again, there are digital thermostats that are not programmable but come with a horde of features and buttons to confuse buyers. Check that your unit can be programmed.
