Most of us would rather DIY everything because it’s cheaper, but did you know that some jobs are better left in the hands of the professionals?

Yes, there are tons of YouTube videos on how to do this and that, and they make it look so easy. But do you think you can install an exhaust ventilation system on your own? If you think you can’t handle it, it’s best to call the experts.

Before going to the nearest hardware store, check this list out and learn why it’s better to hire professional home ventilation and other services instead.

Ventilation

Home ventilation is not just about determining the window size and number. Underneath this seemingly straightforward term is a complex network of wires and cables. More than that, there’s a need to determine which design works best for your house. Some systems are not appropriate for humid places or cold climates, and may not be cost effective at all.

Some other systems need the right mix of indoor and outdoor air to reduce or prevent drafts in cold season. Exhaust ventilation system may also cause back drafting if you have combustion appliances. Improperly installed ventilation may also attract molds and cause moisture problems in your home.

Cooling System Installation, Repair, or Upgrade

While air conditioning systems seem more straightforward to install than a ventilation system, it’s still best left to the experts. Perhaps, the only type of air conditioner you can install by yourself is the portable one, which you can put anywhere in your house. The rest requires the experience and knowledge of the pros.

Just like the ventilation systems, ACs have specific requirements. You need to know the right cable that will run from the power source to the AC because they have different wattage, voltage, or amperage. The wrong cable may not be able to handle the power that will go through it this can cause a variety of electrical problems.

In addition, if you’re planning to buy the split or central type of air conditioning system, you should find the right space for your condensing and evaporative units.

Wiring or Cabling

Anything related to electricity is best left to those who understand it, whether it’s installing new lighting, a dimmer switch, or a GFCI (ground fault circuit interpreter) switch. Handling electrical cables is not only complicated but also dangerous. The Consumer Product Safety Commissions reported that from 2004-2013, about 48 people die every year due to electrocution. Most of these incidents are associated with installing large and small appliances and using ladders. These fatalities occurred during repair work.

The number may seem small, but when a current—even a small one—enters our body, it may severely damage our nerves, tissues, or organs. If it travels through our skin, it can cause burns. In addition, repetitive electrocution may lead to permanent neuropathy, not to mention improperly installed cables may start a fire.

These mishaps usually happen because the wiring is hooked up on the wrong side, or the safety features are not activated. The GFCI, for example, may come into contact with moisture if not installed properly. You know what happens when water and electricity mix.

No matter how simple home improvement projects seem to be, the experts should handle some of them. These projects require ample knowledge of how things work, as well as a mixture of science, math, and art.
