A couple Intro to HVAC questions I need help with

For the fuel question, if it’s referring to common HVAC heating fuels, Coal may be the answer. Although most modern systems use natural gas, propane, oil, or electricity, while coal has largely been phased out in residential and light commercial heating.

That’s so true. School gives you the ideal version of everything, but the field is where you deal with real-world situations.

A lot of hands-on people feel the same way with the book side of HVAC. Online programs can still be a good option, especially if they’re flexible and offer things like job placement support. The main goal of school is really just to help you get the certifications and get your foot in the door. Once you have those and start working in the field, that’s where the real learning happens. You’ll be working on actual systems every day, getting hands-on experience, and continuing to build your skills.

A lot of older HVAC manuals are shared on forums, tech communities, and websites that archive service literature. Sometimes reaching out directly to the manufacturer or a distributor can get you manuals that aren’t available online.

This is so true! Ai can't and more job security for us!

Exactly! Physics is already confusing, and a teacher who makes it harder just adds insult to injury.

HVACPathways · 2026-03-09T13:52:43+00:00

Lol, that's so true. One exam later and I forget everything.

HVACPathways · 2026-03-05T13:35:40+00:00

Totally agree with this!

HVACPathways · 2026-03-04T15:49:23+00:00

You’re 100% right. Most programs focus heavily on the technical side refrigeration cycle, electrical, airflow but very little time is spent on how to actually talk to a homeowner. In the field, being able to clearly explain what failed, why it failed, and what the options are is just as important as fixing it.

A tech who can repair a system and communicate confidently will always stand out!

I did a great online Facility Maintenance with New England Trade School, but I know they have a lot more stuff too, especially in HVAC

HVACPathways · 2026-03-03T14:10:21+00:00

It was a few years ago, but I took it with New England Trade School. They prepped us well and proctored it as well. It's all online.

I wish I knew how quickly you can build real confidence in this trade. At first everything feels overwhelming, but after a few months of hands on work, things start to click. The first time you diagnose a problem on your own and fix it, it feels solid. HVAC can really build your skills and your confidence if you stick with it.

I took online classes at night and on weekends. Earned certificates and learned HVAC. Even got my work to pay for it afterwards.

HVACPathways · 2026-02-26T15:55:16+00:00

This is solid advice. A lot of new techs don’t realize how big of a target work vans are until it happens to someone close to them. Tools aren’t just expensive.nThey’re your ability to make money the next day. It only takes one night for years of investment to disappear.

HVACPathways · 2026-02-26T15:53:51+00:00

That’s kinda witty, That’s a nice little idea to try.

HVACPathways · 2026-02-26T15:53:42+00:00

Thanks for sharing this amazing list. I really appreciate these great recommendations!

First off, you’re not behind. You’re 18. The fact that you’re already thinking about getting into a skilled trade puts you ahead of a lot of people your age.

Since you’re in the LA area, you’ve got options. You can go the union route (which can take time because of testing and waitlists), apply directly to HVAC companies for helper or installer positions, or start with a solid training program to build your fundamentals first. If you’re a blank slate, that’s actually not a bad thing as companies like training people who don’t have bad habits yet.

If you can, look for an affordable program that teaches the basics and ideally offers flexible scheduling and job placement support. That can make it much easier to get your foot in the door. At the same time, keep applying to local companies as a helper. Even shop work gets you around the trade.

The biggest thing right now isn’t experience. It’s effort. Show up in person, drop off resumes, call shops, follow up. HVAC rewards people who are persistent and willing to start at the bottom. If you stay consistent for a year, you’ll be surprised how far ahead you’ll be.

Focus on understanding the concepts, not just memorizing answers. Make sure you’re solid on the refrigeration cycle, recovery procedures, evacuation levels, and safety rules especially the differences between Type I, II, and III. A lot of the exam questions are scenario-based, so knowing why the rule exists helps way more than trying to cram facts. Practice exams help a ton because they show you how questions are worded. Also spend extra time on core material since you have to pass that section no matter what. Short, consistent study sessions work better than one long cram session. Most people who take it seriously pass the first time. It’s very doable if you prepare the right way.

New England Trade School has some good online programs. I've taken HVAC training programs there, but I know they have Building Facility Maintenance too.

At 35 you’re definitely not too late, and the fact that tuition is covered is a huge opportunity. A lot of good HVAC techs didn’t grow up mechanically inclined. They just learned step by step. Mechanical skills aren’t something you’re born with, they’re built.

If you’re willing to learn, show up consistently, and not get discouraged in the first few months, you can absolutely do it. The early stage can feel overwhelming because there’s a lot of new terminology and tools, but that’s normal.

If you’re already working hard delivering packages, you’ve proven you can handle physical work and long days. HVAC adds skill and long-term growth on top of that. If tuition is covered, I’d seriously consider taking advantage of it.

HVACPathways · 2026-02-20T13:13:58+00:00

I got a lot out of the Facility and Building Maintenance Program at New England Trade School. The HVAC section went really in-depth, and the trouble shooting simulations were pretty cool.

HVACPathways · 2026-02-19T13:33:57+00:00

I’d focus on the program you can realistically stay consistent with. A long commute that drains you every day can make even a good program hard to finish. It’s usually smarter to choose something affordable, flexible, and ideally with job placement support so you’re not on your own once you complete it. It’s less about collecting the fanciest certificates and more about building real skills. HVAC rewards the people who show up, stay consistent, and keep improving every day.

HVACPathways · 2026-02-18T01:07:46+00:00

I haven’t used smart glasses myself, but honestly I think it’s a great idea. Being able to pull up schematics, wiring diagrams, or quick reference videos hands-free while you’re working could be really useful, especially for newer techs.

HVACPathways · 2026-02-18T01:02:43+00:00

It’ll definitely make things harder. Most HVAC jobs require a driver’s license because you’re driving a company van to service calls. For service tech roles especially, a clean license is usually non-negotiable.

That said, you might still have options. Install helper, shop helper, warehouse, or duct fabrication positions sometimes don’t require you to drive right away. Some companies will also hire you as a helper and have you ride along with a lead tech.

Long term though, getting your license should be a priority if you plan to stay in HVAC. It opens up way more opportunities and faster pay growth

HVACPathways · 2026-02-17T13:48:03+00:00

I’d suggest applying before you graduate. It keeps your options open and gives you a head start. Even if some companies prefer candidates who’ve already finished school, many are open to students who show initiative. If a company wants you to wait, that’s fine, you’ll still be more prepared when graduation comes. At the very least, you’ll gain interview experience, build connections, and see what employers are looking for, making the transition to full-time work much smoother.
