Why it is Important to Examine Your Ducts Before a New AC System Installation in San Diego

March 15th, 2012

For most homeowners in San Diego the day of a new air conditioner installation is a great one. It means you can look forward to plenty of days of cool comfort, sheltered from the blistering summer heat that would otherwise make you feel sticky and sluggish.

Before that installation can take place, however, there are many smaller tasks that must be performed. You have to do some research, shop around, consult with a contractor and finally decide on the best system for your home. Finally, you should have your ducts examined.

Your ducts are the pathway by which cooled air will be distributed through your home. Without regular maintenance, ducts are less efficient in transferring air and can cost you money, not only in electricity but in air quality control. Like any major component of your air conditioning system, they need to be properly maintained to work properly.

So, you want your ducts to be in tip top shape for your new AC system. Having a professional inspect them thoroughly prior to installation will identify any damage, dirt, debris, leaks, corrosion or other trouble spots that could impede your air conditioning.

This gives you the opportunity to get any of those problems fixed before the new system is installed. Plus, a professional inspection is an important part of routine duct maintenance anyway. Having it done at this juncture is easier and ensures you know will have a smooth running air conditioner for some time to come.

Having duct work in good repair is vital to the operation of your HVAC system, including the new AC system you want to install. If you are contemplating having a new air conditioning system installed or even if you are not, now is the time to call Cal-West Air Conditioning for full inspection of your ductwork. Especially if you have a forced air heating system and those ducts are used year round, you want to know for a fact that they will work properly in the future, no matter what is hooked up to them.

Furnace Control Boards for Temecula Homes

March 7th, 2012

One way to be a truly responsible Temecula homeowner is to familiarize yourself with the major systems and appliances in your home. By having at least some understanding of how, say, your refrigerator or toilet work, you gain understanding of how to use them efficiently and detect when something goes wrong.

The same is true of your furnace, which can appear to be a complicated piece of machinery. In order to help you get acquainted with your furnace, we will discuss one of its main control components, the furnace control board.

As the name suggests, furnace control boards are responsible for governing the operation of the furnace. At a minimum, a simple furnace control will control the furnace ignitor (e.g., a spark generator or glow coil), the gas valve and the furnace thermocouple, also called a flame sensor.

More complex furnace control boards will also have control over the blowers and/or the built-in diagnostic system.

To simplify things, you can think of the furnace control board as being a driver and the furnace as its car. Just as the driver oversees all the functions and operation of the car from ignition to shutting off the engine, likewise does the control board for the furnace.

A typical operation sequence for a furnace control board goes something like this:

1. The control board receives a signal from the thermostat that the temperature is too low.

2. It starts the ignition system, whether that be a spark generator, glow coil or pilot light.

3. Once the ignitor is hot, the furnace control board initiates the flow of gas through the burners, where it is ignited.

4. The control board keeps the furnace running until it is signaled by the thermostat that the temperature is now high enough, or until it detects something is wrong.

(An example of a malfunction where the control board would get involved is a thermocouple that is not detecting enough heat. In this case, the control board would shut off the gas flow to prevent a leak into the home.)

Furnace control boards are an essential part of your home’s HVAC system. And now, as a responsible homeowner, you know just how important.  If you have any questions please call Cal-West Air Conditioning.

How to Check if Your HVAC System is the Right Size in Pacific Beach

February 28th, 2012

Do you ever feel that your home just doesn’t get cool enough during the warm months or warm enough during the cold months in Pacific Beach? You have tried to adjust your thermostat to the right comfort level but it just never seems right. And on top of that, you notice that your utility bills keep going up and up. Even when you dial up the thermostat in the summer and dial it down in the winter to saving on energy usage, your bills are still about the same.

You could try adding fans and shedding clothes during the warm months or wearing sweaters and crawling under a pile of blankets in the cold months. But do you really enjoy living that way? There must be another solution as to why your heating and cooling (HVAC) system is just not keeping you comfortable – and affordable.

That air conditioning condensing unit sitting in your backyard and the furnace in your basement should be making your home as comfortable as possible. But in many cases, they are not.  That’s because whoever installed those HVAC system components didn’t do their homework on your home. The components were sized incorrectly. If a furnace or air conditioner is sized incorrectly, it usually cannot keep up with the demand for heat or cold and often puts such a burden on the equipment. As a result, regular failures and repair bills are commonplace.

And it may not be the fault of the installing HVAC contractor. Over the years your home may have undergone renovations including additions and new windows, which have increased the square footage or demand for more heating or cooling. Those renovations may not have included upgrades to your home’s HVAC system.

So how do you check for the right size? Call a professional HVAC contractor and ask for an energy audit for your home. The audit will include several key checks including a load calculation, which adds in the size of your home’s living space, number of door and windows where heat loss or gain could occur, and a check of heat loss or gain through leakage in cracks, roofs, crawlspaces, etc. An energy audit will determine what size of furnace or air conditioner is needed to meet the heating or cooling needs of your home and its own individual characteristics. Your HVAC contractor may also factor in the number of building occupants and normal usage patterns, i.e. having a home office or stay-at-home parent versus a working family where your home is occupied mostly at nights or on weekends.

All of these factors are considered when determining the equipment size. In air conditioning jargon, you will hear about tonnage of cooling capacity. An example may be a 2.5 ton air conditioning unit for a 2,000 square foot home. In furnace jargon, you will learn about Btu ratings, which are British thermal units. Most furnaces are sized in 20-25,000 Btu increments. Each is matched to the cooling or heating needs of your home. Your HVAC contractor will likely recommend using a programmable thermostat, too. That way, you can set the temperature of one or more zones in your home to when each zone is occupied.

Make sure you don’t hire someone who “guesstimates” how much cooling or heating capacity you need for your home. Find a qualified professional who will make the correct calculations and who will qualify their recommendations. A properly sized HVAC system will equate to manageable utility bills and above average indoor comfort. You can live with that.  Please call Cal-West Air Conditioning with any questions.

East San Diego Air Conditioning Tips: Things to Check on Your Broken AC Before Calling a Professional

February 22nd, 2012

A broken air conditioner in East San DIego is a stressful situation, especially since you’re considering whether you need a professional to come out. No one likes spending hundreds of dollars on air conditioning maintenance, so before you call anyone, make sure to check these problems. You may be able to fix the problem on your own without spending a dime.

Thermostat

The thermostat is one of the most common problems you’ll have with an air conditioner.  Make sure the thermostat wasn’t knocked out of position and the sensors near your coils are in the right place. Often times, a bumped sensor or a slightly off thermostat can cause this kind of problem and as a result, you’ll be left without steady cooling.

Check Your Filters

Another common problem that can cause issues with your air conditioner is filter clogging. While the system will continue to run with a clogged filter, there are a few issues that might pop up – it could smell funny or you might notice icing on the outside line (a major problem). If you allow the filter to get so clogged as to block the air flow from your system, you can expect a number of problems to crop up.

Blower Belts

Check the system’s blower belt for damage like cracking, excess slack or general wear. A blower belt that isn’t properly installed or that needs to be replaced will reduce air flow which can result in ice buildup or poor air flow – it will make it harder for your system to maintain a steady temperature.

Check the Outdoor Unit

Check to make sure nothing is blocking the outdoor unit. Clean the condenser coils and remove any debris that might have built up around the outdoor unit. Often, slowed air flow is caused by nothing more than leaves piled in front of your condenser.

If none of these problems is the culprit or if you fix them all and your system continues to struggle, it is time to call Cal-West Air Conditioning.

Important Things to Remember When Installing a Central Air Conditioner in San Diego

February 17th, 2012

A good central air conditioner is a huge upgrade for most homeowners. If you’ve been using window units for the last few years or have an older central unit that simply doesn’t get the job done any longer, a brand new central unit will feel incredible. But, before you run out and hire someone to install your new central air conditioner, there are a few things to remember.

  • Space – Make sure you have enough space for both the outdoor unit and the indoor evaporator coils.  If space is limited, there are smaller units that will use less and still provide a decent amount of cooling.
  • Supply Registers – Make sure there are enough registers in your home, in the rooms where you need the cooled air. Insufficient depositing of cooled air won’t keep you cool and will run up your energy bill.
  • Ducting – Check the duct work and make sure it can support an air conditioning system. Seal up any ducts leading into spaces you don’t want cooled like the attic or the basement.
  • Condensing Unit – Clear away a space outside where your condensing unit will be placed. It should be clear of debris and be easy to maintain throughout the year, even in the winter when snow might block it in. It should also be easy to access for installation and annual maintenance.
  • Sizing – When you call a professional, they should properly size your home and match it to a central air conditioner that fits your needs. Something too small won’t provide the level of cooling you need and something too large will cycle on and off frequently, costing you more money and putting unnecessary stress on the machine.

If you’re ready for a central air conditioner and want to start the processor, call Cal-West Air Conditioning who can help you go through each of these issues and make sure your home is ready for the new device. Once you’ve done that, you can select a model and have it installed.

Things to Look for in a New Central Air Conditioning System for Your Mira Mesa Home

February 13th, 2012

When it comes time to buy a new air conditioner for your Mira Mesa home, there are a lot of factors to consider. Beyond the obvious issues like cost, you need to consider how that system will operate after the air conditioning installation is complete. What factors are most important to you? Control? Comfort? Cost? Here are some things to consider when selecting your new air conditioner.

  • SEER – The Seasonal Energy Efficiency Rating measures the efficiency of your cooling system during a typical hour. To calculate this number, we divide the total BTUs of cooling produced by the watt/hours of electricity consumed during that hour. So, the higher your SEER rating, the less electricity is used to produce the same amount of cooling. Standard SEER ratings are between 11 and 15 these days, but some high end units have SEER ratings of up to 20.
  • Controls – How much control do you want of your system? Many air conditioners these days come with multiple speeds, allowing you to control the air flow as well as the amount of energy consumed by the device in cooling. Do you want it to constantly blow at 100% or would you like it to run at 50% to reduce consumption. Another option available in central air conditioners is zone control, allowing you to determine which rooms receive cooling with separate thermostat settings.
  • Dehumidification – Air conditioners are dehumidifiers by default, but not every system offers the same degree of humidity control. Some simply remove moisture as part of their regular operation. Others have more advanced controls to provide specific humidity control throughout the year.
  • Sound Dampening – Newer models have sound dampening features like insulation and vibration isolation to reduce sound. These are also great for weather protection and help to maintain your system for more years.
  • Refrigerants – Most new air conditioners now use the R410-A refrigerant which will be required in all new units starting in 2020, but there are some lower cost units still using R-22. Check to make sure you have the environmentally friendly coolant offered by newer models.

A good central air conditioner will keep your family cool and comfortable for years to come so make sure to do your research and choose a model that fits your needs in advance. If you’re not sure about any one feature, a professional installer can help you make your decision.

Troubleshooting Your Problematic Heat Pump in Carlsbad

February 10th, 2012

If your heat pump isn’t working properly in Carlsbad, there are a number of things that might be wrong. But, where do you start and how do you solve these problems quickly and inexpensively? Here are some tips for common heat pump problems.

Low Air Flow

Your heat pump is designed to provide steady air flow to the entire house. When it was originally installed, the technician sized it to do so. If it suddenly stops providing enough air flow to your entire house or if the air flow it provides isn’t as comfortable as you’re used to, something is probably wrong.

More specifically, there is likely an issue with the heat pump itself since the device will compensate for most external problems by running longer and harder. Some quick heating maintenance will often rule out serious problems, so you should have someone inspect your device as soon as you notice a problem.

Leaky Duct

If there is an external problem, such as leaky ductwork, it tends not to be as noticeable right away. Often, when ducts are leaking, air flow problems will occur only in certain rooms of your home. Even then, the heat pump might be able to maintain the right temperature in those rooms – you’ll just have a higher energy bill because of the energy loss in the ductwork.

The best way to determine what is happening and how best to tackle the problem is to have someone test your ductwork for leaks, a relatively quick process.

High Energy Bill

If your energy bill suddenly increases dramatically, it is usually due to energy loss somewhere in the transfer between the heat pump and the rooms of your home. Leaky ducts can be the culprit, but so too can the air handler or the heat pump itself. If you notice a sudden increase in your energy bill, look for other symptoms like uneven heating or cooling in certain parts of your home or noises coming from the ductwork or your air handler.

No matter what other symptoms accompany the increase, you probably need repairs. Your home may still be comfortable now, but the heat pump can only make up for the problem for so long and in the interim, it is being put under excessive stress that reduces its lifespan.  If you have any questions about heat pumps please call Cal West Air.

How Heat Pumps Can Help With Humidity in Del Mar

February 8th, 2012

Humidity is a big problem for a lot of families in Del Mar. When not properly controlled, excess humidity can lead to damage to your furniture, excess mold growth and dust mites. In the warmer months of the year, this is a big problem. Fortunately, if you have a new heat pump, you have a strong weapon against excess humidity.

Heat pumps have both cooling and heating modes. In the winter, when your heating mode is active, you likely don’t need dehumidification. In fact, you may need a humidifier to keep it from getting too dry in your home. However, in the summer, excess humidity can make everyone uncomfortable.

Air conditioning has long been a natural dehumidifier. Because the process works through evaporation and condensation, water can be extracted from the air by the device whenever it is on.

However, for your heat pump to truly provide the dehumidification you need to remain comfortable, it must first have a dehumidification setting – often called the “dry” cycle. During this cycle, the device will dehumidify your home, pulling air from inside the house and extracting moisture from it through the indoor evaporator coils.

Dry cycling is effective because it doesn’t draw new air in from outside to cool your home. It uses the same air already in your home and can therefore remove humidity over time. While new air is draw into your home through vents, the system is designed to continuously cycle the humidity out of the air and keep you from being uncomfortable.

Choosing the Right Heat Pump for Humidity Control

Not all heat pumps offer humidity control settings, so contact Cal-West HVAC experts about your needs before selecting a new model for your home. Make sure it offers the dehumidification options you’re looking for and can cover the full area of your home.

Encinitas Indoor Air Quality Question: What Type of Air Cleaner Is Best for People with Pets?

February 6th, 2012

Lots of people in Encinitas have pets, and they are a great addition to your family. However, pet ownership has one very obvious drawback: dander. The fur, dry skin cells and other debris that pets carry around flakes off their bodies and onto your furniture and rugs. The also means they inevitably wind up in your air, recirculated through your whole house via your HVAC system.

Or at least, that’s what happens if you don’t have an air cleaner or some sort of air filtration system. This leads many pet owners to ask, “what is the best air cleaner for me?”

With all the choices in air cleaners, the choice can seem daunting. If the goal is specifically to filter out pet dander, it becomes somewhat easier.

Pet dander is quite large in size relation to other indoor air pollutants, so many air cleaners are equipped to do the job. You can use an air cleaner with a standard pleated HEPA filter, or one that uses electrostatic technology. You will want to make sure that the HEPA filter is rated to handle pet dander. A MERV rating of 8 or more is recommended.

Once you have an air cleaner installed, make sure to change or clean the air filter frequently, in accordance with manufacturer instructions. A clogged air filter won’t help eliminate pet dander from your household air and can actually degrade the operation of your HVAC system’s air handler.

In addition to installing a high quality air cleaner with a HEPA filter, you can also help reduce the amount of pet dander floating around your Encinitas home by keeping the place clean. Vacuuming often and dusting hard surfaces weekly keeps pet hair and dander from being drawn up into the HVAC system, which reduces wear on the air cleaner. If you have any questions about how you can improve your indoor air quality, contact your HVAC pros at Cal-West.
