While not every HVAC service company is equal, myths and misconceptions have been around since the first air conditioning unit was invented. There’s information that’s not accurate, half truths, or plain wrong. The endeavor of this educational article is to set the record straight.
1. For instance, one of them is that the unit is fine because it sounds fine. Perception isn’t helpful in this case; internally the unit may be showing signs of a breakdown without warning. A qualified technician will diagnose any issues that aren’t obvious to the eye and make the needed repairs.
2. Another one is that the AC unit needs a new shot of Freon every summer or/and winter. If the unit is a closed-type, it should never have any leaks. All things being equal, the unit should always run on the original Freon that was first installed. Most modern AC units have safeguards that prevent any leakage.
3. Maintenance plans aren’t cheap. In the long run, maintenance plans are less expensive than if there was a major repair to be performed in the first place. This is because with a good plan from a reputable company, any preventive work is done to eradicate any future damage. This saves money, time, and plenty of headaches.
4. For sealing ducts, duct tapes work best. In reality, the opposite is true in that mastic tape, used properly only by HVAC professionals, will effectively seal any duct. Duct tape doesn’t work well in dirty environments.
5. Blocking off some of the air vent will save in the long run. This is an old wives’ tale that has no credibility. Blocking off a vent makes the unit work much more harder, using up more energy. Because the unit has to work overtime, the likelihood of damage is much higher.
6. My home warranty covers any HVAC expenses during construction. Such a warranty only covers construction materials or problems during the construction and installation aspect. Homeowners are on the hook for any HVAC repairs.
7. Fiberglass insulation will keep the heat inside in winter. This is akin to placing a Band-Aid in a major injury. Heat from the unit is still required; it could be dangerous and energy-wasting if an opening where heat escapes isn’t sealed properly. A professional will prove helpful.
8. HVAC systems are inexpensive to operate. Buyer beware! A home’s energy bill is usually around 50% HVAC usage. Depending the time of the year, the type of unit, and square footage of the home, energy usage will vary. Having a maintenance plan will save money.
9. All technicians are male. Over the last 10 years there has been an increase of women who attend HVAC school. They perform the job as well as their male counterparts. Furthermore women homeowners may be more comfortable with a woman servicing their unit.
10. Leaving a fan running in a room when it’s empty will cool the unit faster. A fan will move the air against an occupant. Therefore the air temperature isn’t lowered; rather, valuable energy is wasted. It’s best for fans and AC units to be used when there’s people in a room.
11. It’s best to purchase the biggest unit because they work best. This misconception is so wrong! HVAC units work more effectively if they’re specifically suited for the square footage of a home and the needs of the homeowner.
12. The temperatures vary from room to room because the main unit is old. In this case, it may be something small, such as replacing a thermostat, or taking measures to improve the air flow so the unit can cool rooms evenly.
13. Price is the most important factor when making a purchase. This is huge misinformation!The majority of HVAC units are affordable; payment plans are created. What’s most important is who makes the installation. Performance is reduced by as much as 30% due to incorrect installation.
14. My old unit isn’t strong enough; it needs to be replaced. This may not be necessary; a technician can do an air duct assessment and correct any issues; a well-running air duct will in turn, improve the efficiency of any old unit and extend its life.
Now the reader has seen the light with the correct information. Truth is really freedom!
