HVAC Engineers share their 5 top tips and tricks to make their job easier

Have you ever looked back and realised how many tips and tricks you have picked up over the course of your career? Every tradesperson knows that each job is different and some things just have to be learnt the hard way, but as an apprentice this can sometimes seem like a big hill to climb.
Aspen Pumps Group speaks to experienced HVAC installers for their best “nuggets of wisdom” and things they wished someone had told them when they were starting out.
1 – The trouble with flare joints
“Cut out flare joints on mini split wall mount units and solder the piping onto them – they are so awkward to get at once installed! Another option is to braze the flare joints on instead which will remove the potential of future leaks from that area.”
2 – Support your pipework correctly
“Aspen and other manufacturers offer an array of pipe work supports for every installation scenario so there should be no excuse not to do this every time and make life easier for the next engineer to work on the unit.”
3 – Think about future access
“I often see split type outdoor units hung externally on wall brackets with an insufficient gap behind the unit. This prevents the next engineer from being able to correctly clean the coil and also reduces performance. I also frequently see BC boxes hung tight to concrete slabs. With access to inside most BC boxes being from the top, it becomes a massive job to get in and diagnose a fault if this is done incorrectly.”
4 – Use the right tools 
“I think every install engineer should have a torque spanner. There may be fewer and fewer flare nuts these days but where there is one it’s important to ensure you create a good flare and tighten to the correct torque setting as stated by the manufacturer. I often see quarter inch flare nuts over-tightened which causes the flare to deform.”
5 – Don’t skip the commissioning stage! (Even if it’s ‘only’ a single split!)
“As well as the obvious checks like condensate drains, temperatures, operational data etc, there are now often many settings to fine tune the system. Settings for various indoor unit heights for example ‘high ceilings’ and varying settings for static pressure on ducted type indoor units will massively effect the units’ performance if not set correctly. Thermistor reading location is also another important decision to make. If the system is not set up correctly you can almost guarantee you will be getting called back to site to rectify it. Taking simple steps at initial set up to ensure the system is running optimally will help ensure you build and maintain a good reputation.”
6. Take pride in your work. “I was told as an apprentice, “You’re only as good as your last job” and I still carry this thought with me every day.”
