Here we look at five more common HVAC installer mistakes:
1. Not calculating adequately
When you fail to do the maths properly, you will inevitably provide a poor service to your customer. If you carry out jobs in the same way that you did 30 years ago, this is helping no one. Being on top of the numbers involved as technology progresses is key.
2. Not looking at the building system as a whole
All HVAC contractors should look at the whole building as a functioning system, seeing the HVAC system as one amongst many.
Think about pushing up airflow in an area where heat-generating equipment such as servers will be installed; making sure that air intakes will not be in a place where unpleasant smells or toxic gasses could occur; and planning a system to allow easy updates should alterations to the other building systems occur.
Amongst the parts you may need is a cartridge filter, which is available from stockists such as https://www.dustspares.co.uk/filters/.
3. Failure to ensure fire safety
Any type of a fire has the potential to be dangerous, particularly if carbon monoxide is produced. Ventilation system designs must be altered to stop carbon monoxide accidentally entering occupied spaces. It is vitally important to prevent excessive negative pressure around a central heating unit for safety reasons.
4. Using in-house estimating
If a small HVAC firm offers its own estimating services, the quality of work and turnover time can be affected. Modern estimating is complicated, involving state-of-the-art software; therefore, you should hire a firm that uses professional HVAC estimating.
5. In-house duct manufacture
Traditionally, HVAC contractors have used their own in-house shops to make ductwork. This has traditionally ensured quality, timely delivery and direct control of production; however, this has not worked so well recently because:
– Skilled labour is not readily available.
– Poor purchasing power amongst small companies means higher-cost materials.
– An infrastructure is required for maintaining equipment and inventory.
– Keeping in-house shops busy is difficult when the economy falters.
– Contractors have marketed their shops for outsourced projects, but others prefer going to the supplier.
– Contractors come to realise their key competency is installation, not manufacture.
– Inefficient in-house manufacturing eats up profit.
– There is a mix of labour problems, materials procurement problems, inventory problems and project management problems.
Thank you for sharing a detailed post. Fire safety installation is important to step to maintain home safety. Make sure to check the professional website beforehand to choose the right services of right expert.
Yes we sometimes ignore the HVAC installers when they are working. A common person with zero knowledge of how the HVAC is installed cannot find any defect but after reading your blog I think anyone can pinpoint the problem if they can see during HVAC getting installed.
