How old is your HVAC system? If the answer is somewhere north of 15 years, or if you have been calling for repairs more often than you would like to admit. It might be time to start thinking about a replacement before the next winter makes that decision for you. But what does a new HVAC installation in Idaho Falls actually involve? What should you ask and prepare for? RSJ Mechanical has been answering those questions for homeowners since 2017. This post breaks the whole process down so you know exactly what you are getting into.
Step 1: The In-Home Assessment
A proper HVAC installation in Idaho Falls starts well before anyone shows up with equipment. The first step is a visit to your home so we can take measurements and evaluate your existing ductwork. We will also figure out what size system your home actually requires.
This step matters more than most people realize. An oversized system will short-cycle. This means it turns on and off too frequently without completing a full heating or cooling cycle. An undersized system will run constantly. It will still fail to keep up on the coldest or hottest days. Neither option is good for your comfort, your energy bills, or the lifespan of the equipment. Idaho Falls winters can push temperatures well below zero. Our summers are no walk in the park either, so getting the sizing right is not optional.
During the assessment, we also look at the condition of your ductwork. Old, leaky ducts can rob a brand-new system of up to 30% of its efficiency. That’s before the air even reaches your living spaces! We will let you know, honestly, whether your existing ductwork can support a new system. Or whether repairs or modifications would help you get the most out of your investment.
Step 2: Equipment Selection
Once we know what your home needs, the next conversation is about choosing the right equipment. This is where homeowners often have the most questions, and rightfully so.
For most Eastern Idaho homes, we are talking about a matched system. A furnace and air conditioner that are designed to work together for peak efficiency. Some homeowners are also great candidates for a heat pump. This handles both heating and cooling in one unit and can be surprisingly effective. Even in colder climates, when paired with a backup heat source.
We install industry-leading brands built for reliability and energy savings. We will walk you through efficiency ratings (SEER for cooling, AFUE for heating). Our technician will explain what the numbers mean for your monthly utility bill. We help you find the right balance between upfront cost and long-term savings. RSJ Mechanical offers flexible financing options, so a quality system is within reach. Even if the timing is not ideal.
Step 3: Preparing for Installation Day
Once you have selected your equipment, we will schedule your installation and give you a clear timeline. Most residential HVAC installations in Idaho Falls take one full day. More complex projects involving ductwork modifications may take longer. We will always be upfront with you about what to expect.
On your end, the main preparation is making sure the area around your furnace and the space where your outdoor unit will sit are accessible and clear. We take care of the rest.
Step 4: The Installation Process
On installation day, our technicians arrive on time and get to work. Here is a general outline of what happens:
Removing the old system. We disconnect and carefully remove your existing equipment. If your old unit contains refrigerant, we recover it properly in compliance with EPA regulations.
Installing the indoor unit. The new furnace or air handler is positioned, leveled, and connected to your existing ductwork. Any duct modifications identified during the assessment are completed at this stage.
Installing the outdoor unit. Your new air conditioner or heat pump condenser is set on a pad outside. It is properly spaced from the structure and secured. Refrigerant lines are run and connected.
Electrical and gas connections. All wiring is connected to your existing AC disconnect. If no AC was previously there, then an electrician is needed to install an AC disconnect. Gas lines are connected and pressure-tested for the furnace. Safety is not rushed at this stage.
Thermostat installation and programming. If you are upgrading to a new thermostat (which we often recommend alongside a new system). We install and program it for you. A properly configured thermostat is one of the easiest ways to improve efficiency and comfort right from day one.
Step 5: System Testing and Walkthrough
Before we consider the job done, we run the system through a complete operational test. This includes checking airflow at every register. Confirming that the furnace ignites and runs through a full cycle. Make sure the thermostat communicates correctly with both the heating and cooling functions.
Once everything checks out, we do a walkthrough with you. We show you how to operate your new system and thermostat. Walk through filter replacement schedules (typically every one to three months). Lastly, answer any questions you may have. You will also receive documentation for your manufacturer’s warranty, and we will explain what it covers.
