Common HVAC Mistakes To Look For


Air Conditioners

Having a reliable HVAC system in Southern Florida is a must any time of the year. High heat, excess humidity, and stale indoor air are all problematic, exacerbated even further if your system does not work properly.


As a homeowner, you want to ensure that your HVAC system is working correctly to avoid the discomfort that comes with high temperatures. How do you know that you’re set up for success? As most of us are not equipped to handle HVAC system repair and diagnosis, calling a technician to regularly assess your system is always a good idea. What to do in the meantime?


Simple mistakes you can look for

The good news is, there are clear indicators of system success….and system failure. Taking note of these issues and knowing who to call will be vital to maintaining cool, comfortable temperatures all year long. Even with limited experience, you can still diagnose a potential problem and call in a trusted technician to take care of it before it becomes a costly repair. Look for these signs of trouble:

  1. An improperly sized AC--An air conditioner that is too large or small for your living space is one of the most common HVAC mistakes one can avoid. A unit that is too small can never quite catch up to the cooling demands of your home, while one that is oversized will cycle on and off, never quite controlling humidity levels or cycling air properly. The constant stress on your unit will shorten its life span and age it prematurely. Ask an HVAC professional about your needs according to the square footage and layout of your home. He will then provide expert guidance through the process of selecting the right unit for you.

  2. A restrictive air filter--Air-filter manufacturers may sell you the line that you need an ultra-restrictive filter to make your unit perform more efficiently. Still, some of these “efficient” filters are so small that they can actually trap bacteria and viruses, circulating them throughout your home. The primary function of your air filter is to protect your blower from debris that will damage the system. Talk to your installer about your filtration needs, and find a filter that can protect your system while also protecting your health.

  3. Installing outdoor coils too close to obstructions--The outer coil of an air conditioning unit needs to stay at or near the ambient air temperature around it. If you attempt to disguise your unit with landscaping or other types of covers, it can cause your unit to run much hotter than is considered safe. This hot-running system will cost you more money to cool your home while becoming a safety hazard at the same time. Make sure your outer coils are far away from walls, shrubbery, retaining walls, and other obstructions that could cause it to run harder than it normally would.

  4. The presence of refrigerant additives--Some companies peddle refrigerant additives to homeowners, claiming that these products work to make your system run more efficiently. In actuality, the manufacturer of your unit has designed it to work optimally with specific products. Adding outside refrigerant or other additive chemicals is extremely risky business, as most of these refrigerant chemicals are highly volatile if not handled properly. Don’t be tempted by these third-party sellers; stick to what your manufacturer and HVAC technician suggest when it comes to boosting energy-saving efforts.

  5. Using cleaner on the coils--Keeping your HVAC system clean is the most efficient way to preserve its optimal performance. Standard cleaners that introduce acidic or alkaline chemicals are another common mistake that homeowners make. You can clean most debris off of outer coils with a stream of low-pressure water. Make sure you turn your unit off first, then use your garden hose and a bit of finger pressure to gently wash down both coils and cooling fins.
