Why Is My AC Unit Blowing Hot Air? Check These 6 Things First

December 18th, 2019

An air conditioner installed in a homeAren’t Hawaiian “winters” the best? We can save money on our electric bills by just popping open the windows to let those cool island trade winds blow through the house.

When that first scorcher of the season hits, that AC unit needs to work and it needs to work well. No one wants an AC unit blowing hot air in their face!

6 Reasons an AC Unit is Blowing Hot Air

1. The Settings Got Messed Up

It may sound simple, but you’d be surprised how many times we get to a customer’s home and realize someone has just bumped the settings and screwed things up.

Always double-check the settings first. Sometimes, they may need to be calibrated by a professional too.

Remember that if an AC unit is set to “on” rather than “auto,” it may keep blowing room temperature air when it’s not cooling – like a fan.

2. The Intake Vent is Blocked with Debris

If the unit is covered with leaves or dirt, that means it isn’t getting air which can lead to an AC unit blowing hot air. Cut off the electricity and clean off the intake vent.

3. The Coils are Dirty or Fins are Bent

Even if an AC unit looks clean, that doesn’t mean the coils aren’t clogged up with gunk.

For window units, cut off the electricity and pop open the back panel. Vacuum out any dust, hair, and dirt. Use a brush and some cleaner to wipe down the condenser fins. If they’re bent, use a special fin comb to straighten them out.

Make sure to wear leather gloves for this.

4. The Filter Needs a Change or Cleaning

While the AC is open, we recommend cleaning or changing the air filter. It’s important to clean your AC filter once a month during the summer when it’s running all the time.

5. The AC Unit Needs Refrigerant or Freon

For an AC unit blowing hot air, icing over, leaking, or triggering sky-high electric bills, freon might be the culprit. This is a fix best left to the professionals, so give us a call.

6. There’s an Electrical Issue

Power outages can lead to blown fuses and brownouts. Remember that AC units draw a ton of power!

Check the fuse box to make sure all the switches are on.

Inside the unit, faulty wiring is also common.

Whether an AC unit is tipping the circuit breaker or needs an internal wire fix, this is another job only a professional should handle.

AC Unit Still Blowing Hot Air?

In many cases, we can fix an AC unit blowing hot air with a simple tune-up so there’s usually no need to replace the whole thing. Our experts will conduct a 32-Point Safety Inspection & Tune Up to diagnose the specific problem and get your AC running icy cold again!

Why Is My House So Humid in the Summer?

December 18th, 2019

Water on a plant in a Hawaii homeHawaii is known for its ideal weather. Cool nights and sunny days.

It isn’t always humid on the island, but when that humidity kicks in, it’s bad. 

But I’m running the AC non-stop. Why is my house so humid?” We recommend looking at the AC unit first to see if that’s the problem.

What’s the Ideal Home Humidity Level?

For humans, 40% to 50% is the perfect humidity level for homes.

If the humidity level drops below 30%, it can cause viruses to spread, make dry skin, worsen eczema, or lead to respiratory irritation.

If the humidity level jumps over 50%, this can cause mold growth and dust mites, so bringing down the humidity level is critical.

Why Is My House so Humid in the Summer and How Can I Fix It?

Keeping the humidity level in a normal range is important to reduce the spread of mold and keep your house healthy. Check these three things first before you call us.

The AC Unit Is Too Big

With AC units, bigger doesn’t always equal better, whether it’s central air or a window unit.

AC units have something called an evaporator coil, which cools the air’s temperature and removes humidity.

The thing is, these processes happen simultaneously, and removing humidity from the air takes time. If an AC unit is really big and cools down the room within 10 minutes, that means it hasn’t had the chance to remove all the moisture from the air.

Schedule an appointment and we can get to the bottom of it.

The AC Coils Are Frozen or Dirty

Air conditioners need regular maintenance to function properly – just like a car! If an AC unit’s coils are clogged up with dust, dirt, hair, or frost, it can’t do its job dehumidifying the room.

Cut off the electricity to the unit and pop open the cover. Make sure the fins aren’t smashed, clean out or replace the filter, and ensure there’s no visible ice anywhere.

It’s Not the AC – It’s You

Many people don’t realize that moisture seeps into the air of their home from basic appliances and activities. Keep these things in mind:

  • Houseplants – especially when overwatered – can push moisture into the air.
  • Coffee pots, clothes dryers, and boiling water
  • Cracks in the walls and poor insulation – both notorious across the islands
  • Those signature Hawaii jalousie windows that lack an airtight seal
  • Steamy showers
  • Talking, heavy breathing, and parties (large groups of people)

How Often Should I Service My AC Unit? What You Need to Know

December 18th, 2019

Mini Split UnitIn Hawaii, most of us are lucky enough to enjoy cool breezy nights–even in the summer.

For those of us living in low-lying or humid areas, however, a high-functioning AC unit is necessary year-round.

One of the most frequent questions customers ask us at Island Comfort is “how often should I service my AC unit?”

Well, it depends! Let’s take a look…

How Often Should I Service My AC Unit and Why Does It Matter?

People living in a valley that doesn’t enjoy much wind or somewhere wet like Waialua get stuck running their AC unit 24-7 year-round. In that case, we suggest professionally servicing the AC unit every three-to-six months or so.

We recommend a 32-point Safety Check & Tune-Up. Our experts will pop open the AC and make sure everything is running smoothly, clear out debris, check the wiring, and implement changes on all the technical stuff that non-professionals should not be touching.

For anyone lucky enough to live upon a ridge where it isn’t necessary to run the AC all winter, an annual 32-point Safety Check & Tune-Up should suffice. Give us a call in the spring so we can make sure the AC is ready to handle the summer heat.

Why Is It Important to Service My AC Unit?

Air conditioners are delicate pieces of machinery.

Dirt, debris, and gunk cause them to overwork themselves and run hot which can drive up electric bills and lead to increased risk of breakdown, both of which are expensive, especially in Hawaii!

A dirty AC unit or filter also leads to dirty air. For anyone with allergies or sensitive skin, a slight increase in dust mites, mold, and microorganisms can make a massive difference.

Can I Service My AC Unit Myself?

Servicing your air conditioner isn’t as easy as it sounds.  Maintenance tasks like checking the wiring and freon leaks are definitely best left to an AC repair company that won’t risk your safety and/or cause damage to your unit. While you could help the health of your air conditioner by changing your filters regularly and other minor forms of maintenance, this will not increase the life cycle of your HVAC unit compared to what we provide in our 32 point safety check and tune-up. 

Let Us Do the Dirty Work
