These Facts Will Change the Way You Think About Air Conditioning

Monday, July 30th, 2018

Air conditioning is a standard part of life in So Cal. Most modern homes here are built different-ac-componentswith ACs in mind, and the regular hum of an air conditioner’s compressor is as much a part of the soundtrack of the summer as the crash of waves on the beach.

But people often don’t know much about the marvels of contemporary air conditioning. We’d like to share some facts about air conditioning that may alter how you look at them.

Problems With an Air Conditioner’s Condensate Pan and Drain

Monday, July 2nd, 2018

ac-unit-insidesAn air conditioning system doesn’t use water to cool off the inside of a house—but water condensation is a part of the AC’s heat exchange process. If you listen to the air conditioner’s indoor cabinet when the system is running, you’ll occasionally hear the drip of water. This is the vapor from the air that gathers along the evaporator coil. As the coil evaporates the cold refrigerant moving through it to draw heat out of the air, it also draws out moisture in the air, where it condenses on the coil.

What happens to this water? It drips off the coil and falls down into a shallow condensate pan. A pump then removes the water through a drain and removes it from the house. For the most part, you won’t have to think about it. Unless…

Help, My Thermostat Is Broken!

Monday, June 4th, 2018

hand-setting-thermostatYour house starts to heat up to uncomfortable levels as the outdoor summer temperatures soar. What do you do? You probably go to the central thermostat in your home to make adjustments to it. You set a comfortable temperature (we recommend 78°F as an energy-saving setting) and then let the AC handle the rest.

But what if nothing happens? The thermostat screen is blank, or the AC compressor/fan doesn’t turn on. If your thermostat is not working, you may need the assistance of HVAC professionals to take care of the problem.

Spring Reminder: AC Maintenance Is Vital!

Monday, March 26th, 2018

checkmark-greenWe’ve had an unusually cold and rainy end of winter and start of spring. True, our idea of “cold” is mild compared to most other places in the U.S., but you probably got more use out of your heater in the last three weeks than in all of the winter season.

But the hot days are coming—and in Southern California the hot weather means serious business. Having your air conditioner properly maintained in early spring is essential for getting the best from your AC through the middle of the year and into our often hot fall season.

Warm October: Treat Your AC So It Doesn’t Trick You

Monday, October 23rd, 2017

air-conditioner-on-leavesOctober is when most places start to experience the cool of fall, when the leaves begin to turn. By Halloween, the true autumn chill has set in.

We don’t live in “most places.” Southern California experience warm and sometimes hot Octobers, and we’re in the middle of one of those right now. Because of this, you want to make sure that the “trick” part of “trick or treat” isn’t your air conditioner tricking you and failing its job. The scariest things you want to encounter during Halloween are old horror movies on TV, not a busted AC that’s turning your home into a heated nightmare.

The Importance of Working with Professionals for HVAC Service

Monday, June 12th, 2017

Air-conditioner-repairmanYou can’t enjoy a comfortable lifestyle in Southern California unless you have a working air conditioning system. And to have the most reliable air conditioning system, you must turn to trained professionals for all air conditioning services and HVAC services in general. This includes installations, replacements, repairs, and maintenance.

We understand homeowners are looking for places where they can save money on their annual budget. But attempting to shave off costs by going with amateurs for HVAC services can backfire—and probably will. Be cautious of amateurs who make big promises about what they can do for only a small amount of money.

The Problem with Coil Leaks in ACs and Heat Pumps

Monday, November 2nd, 2015

One of the most common repair issues that an air conditioner or heat pump might encounter during its lifetime is a leak in the refrigerant coils. The indoor coil of your AC/heat pump is one of the most important components of the system: it’s the location where an air conditioner removes heat from the air by evaporating the refrigerant within the coil. The coil does the same function in heat pumps when in cooling mode, and when in heating mode the coil releases heat by condensing the refrigerant inside it.

Help! My Air Conditioner Is On But No Air Comes Out

Monday, June 22nd, 2015


When ever the weather heats up we get a lot of air conditioning service calls. The common complaint is, “I can hear the air conditioner turn on but no air is coming out.” That’s because coil inside the AC unit is frozen. One reason for AC freeze-up is that the air flow coming into or out of your system is blocked at some point. You see the air conditioner operates when free flowing air passes through the inner components of your air handler, is cooled by the refrigerant filled coils, and then blown out into your living space.

When air is cooled condensation occurs.

Just like air produces condensation when it comes in contact with the outside of a cold glass, central AC units can generate around 20 gallons of water per day. If the air doesn’t move through the system properly, water can build up on the coil and freeze. More and more condensation will build up and freeze until your coil becomes a solid block of ice.

Here is what to do:

1. Turn the AC off

Nothing can be done until the ice melts, usually around 24 hours. Call and let us know that you need a service call at 818-780-0701. Once your AC defrosts we will be able to repair the problems and get you on a regular maintenance plan to make sure that problems like this never happen again.

2. Change or clean your air filter

Changing your air filter keeps the air in your home safer and cleaner, but it also saves energy, improves cooling performance and lengthens the life of your HVAC system. Filters should be cleaned or replaced at least every three months (or more often, depending on your system requirements). High-quality HEPA filters will yield the best results.

3. Keep A/C unit clear of weeds, vines and other debris

These materials can clog the unit and cause efficiency problems. This is a maintenance job you can do yourself in between professional routine maintenance for your HVAC system. It’s important every year to get a complete tune-up and clean out any dirt or grime that may be slowing things down.

4. Keep all vents clear and unblocked

Blocked vents will increase the pressure on your air conditioner and prevent the house from cooling consistently or evenly, so make sure vents aren’t blocked by furniture and remove any dust or debris that might be clogging them up.

The Most Common Air Conditioner Problems

Wednesday, October 1st, 2014

Air Conditioning System Not Cooling Properly

There are several common problems that could cause an air conditioning system in Los Angeles not to cool properly:

Refrigerant

Oftentimes air conditioning problems are a matter of low refrigerant charge, which means the AC unit could be leaking. The solution would be to find the leak, repair it, and recharge the system.

Thermostat Issues

Check your thermostat to make sure it’s properly set and that it is reading the correct temperature.

Drainage Problems

Sometimes the air conditioner’s condensate drain gets clogged and needs to be flushed out. Things that cause air conditioning condensate drainage lines to clog up are pet fur, dust, or something coming into the drain from the outside such as plants or dirt.

Dirty Filter

Many heating and cooling problems in Los Angeles can be solved by changing a dirty filter. Our Kilowatt main office is right at the interchange of the 405 and the 101 freeways in Sherman Oaks so we know how dirty the air in our city can be.  The air closer to freeways has been shown to carry more particulates. That makes sense, but it may surprise you to learn that indoor air is 30-40% dirtier than outdoor air! So HVAC filters in Los Angeles get clogged more frequently. A clogged filter restricts airflow through the AC system, decreasing it’s efficiency and reducing its ability to effectively cool the air.

If your air conditioner is not responding at all, there are a couple of issues that may be the cause:

Thermostat

If your thermostat is not working it may need new batteries, it could have a loose wire, or it may need to be replaced entirely.

Electronic Control Failure

Sometimes the electronic controls for the fan or the compressor wear out. The frequent turning on and off the the equipment can cause that tiny part to fail and need to be replaced.

Not Enough Air Flow

Sometimes the air conditioning is running and cooling but the flow of air coming out of the vents is weak and ineffective. Causes could be:

Problem with the Ducting

We have seen leaky ducts that have been crushed or broken by other workmen, rodents, or storage boxes pushed into an attic and accidentally into duct-work. Sometimes ducting becomes clogged or constricted.

Clogged Filter

Problems stemming from a dirty filter are so common we have to say it twice. A filter is usually placed inside the return air grill which is bigger than the other grills in your home. Sometimes a filter is near the blower motor of the furnace. All heating and air conditioning systems should have a filter to, at the very least, keep the interior components of the equipment from getting dirty. when filters get dirty they restrict the airflow and cause several different issues. Weak air flow is one of those issues.
