Drain Pan Problems with Your Air Conditioner

May 25th, 2015

Your air conditioner relies on electrical components to do its job, which means that water is an absolute no-no. Yet is also creates condensation when it cools the air, which liquefies the ambient moisture in the air leaving droplets similar to morning dew on the coils. How does it function without shorting out? The drain pan, which collects the condensation safely before removing it from the system with a line. Drain pans are an invaluable part of the system, and like any other component they can run into problems from time to time. In San Diego, CA, you don’t want to hesitate when that happens, since our humid sea air can create a lot of condensation. Drain pan problems usually boil down to a few simple things, but the consequences of letting them slide can be devastating. Continue Reading

Why Is Sizing Important for My Air Conditioner?

May 18th, 2015

Air conditioning technicians are trained to size new units properly for the homes they’re intended to serve: matching their power levels so that they’re neither too large nor too small. We like to refer to it as The Goldilocks Rule, and it’s a vitally important step when installing a new air conditioner. This is the right time to install new units in San Diego, CA, while the weather is still fairly mild, and once you’ve decided to pull the trigger, you need to get your home sized before installation begins. The steps are a bit technical, factoring in such elements as square footage, insulation, the presence of a large kitchen (which requires a more powerful air conditioner to offset heat generated by cooking and dishwashing) and the amount of insulation in your walls and attic. “But why is sizing important for my air conditioner?” you ask? We’ve provided a few answers below. Continue Reading

How Does Refrigerant Affect Air Conditioning?

May 11th, 2015

Summers in San Diego, CA aren’t as brutal as they are elsewhere in California, thanks to our coastal breezes and proximity to the shore.

The more you understand about your system, the better equipped you’ll be to notice big problems while they’re still small. And understanding air conditioning begins with the refrigerant. How does refrigerant affect air conditioning? Read on for the answers. Continue Reading

What Can Happen When My AC’s Refrigerant Runs Low?

May 4th, 2015

Many people don’t know this, but your air conditioner was made to operate with an exact amount of refrigerant. This means that an amount even a little too low can have adverse effects on the system. Why? Because your air conditioner is a closed system. The refrigerant isn’t depleted during use; instead, the refrigerant stays at a constant level and cycles through as your air conditioner operates. This is why, when the level is off (most typically too low), problems can develop with your system. Refrigerant issues should always be handled by trained experts for several reasons, the most important being that refrigerant is a classified fluorocarbon and requires certification to handle. When you hire an expert from Cal-West Air Conditioning, you can rest assured that our AC specialists have both the certification and training needed to properly repair any refrigerant leak you may have.

Is It Time for a New Air Conditioner?

April 6th, 2015

We’ve got the perfect combination of warm days and cool nights right now, but soon enough we are going to need our air conditioners to work around the clock – is yours up to the job, or is it time to look for a replacement? It can sometimes be hard to part with an existing air conditioner if it’s still running, but just because it’s running doesn’t mean it’s running well or that you should hang on to it. So when is it time to consider a new AC for your San Diego, CA home? The air conditioning experts at Cal-West Air Conditioning have a few suggestions on important factors to consider:


Did you spend a lot of time and money keeping your air conditioner operational last year? Are you starting this year looking at more? Nursing a system along can add up to a lot of money in a short amount of time, and it may be money that you could have been putting toward a new, reliable system.


The average lifespan for a split-system air conditioner is 10-12 years; for a heat pump system, the average lifespan is about 20 years. If your air conditioner has reached its maturity, it may be time to consider the installation of a new system. Why? Aging systems are far more prone to malfunction and breakdown; they are also going to be less energy efficient simply because they are aging systems. At a certain point, the amount of money you put into an aging system may not give the return you need.

Poor Performance

Does your current air conditioner struggle to achieve your set temperature? Is it sluggish? Are you seeing your energy bills go higher each month even though you haven’t changed the way you use your AC? These are all signs of poor performance, and they can cost you money, time and comfort. When you combine poor performance with aging and/or repair work, it’s time to consider if you are better off spending your money on a new, reliable, efficient system.

No one should attempt to replace an existing air conditioning system without the help of trained pros, and this is where the experts at Cal-West Air Conditioning come in. If it’s time to replace your AC, call us today!

At What Point Should You Have Your Ducts Tested?

March 27th, 2015

Countless homeowners throughout the world depend upon their ductwork in order to distribute both heated and cooled air throughout their living spaces. The popularity of this method is easy to understand. By utilizing air ducts, one can promptly and effectively distribute conditioned air throughout an entire household, and with great efficiency as well. Of course, this level of performance quality is only attainable if one’s air ducts are in fine working condition. This may not always be the case. Your air ducts may be compromised at some point, or they may simply have been poorly designed and/or installed. At some point you may wish to schedule comprehensive air duct testing services in San Diego. When you choose to do so, make sure that it is Cal-West Air Conditioning that you call.

A number of different issues may develop which can prompt homeowners to consider having their ductwork tested. One such issue is if different areas of their home are consistently less comfortable than others. If you do not utilize a zone control system, then your ducted HVAC system ought to heat and cool your home evenly. If this is not the case, then you may have leaks in your ductwork, or a specific route of the ductwork servicing a particular area may not be optimal. Air duct testing will allow us to figure out precisely what the problem is. Only then can it be resolved entirely.

Another reason to consider scheduling professional air duct testing is if you find that it is costing far too much to keep your home comfortable. This again may indicate that there are leaks in your ductwork. As conditioned air escapes your air ducts, your HVAC system is going to have to work harder in order to achieve and maintain the target temperatures set at your thermostats. The more energy that is consumed, the more money it is going to cost to both heat and cool your home. By testing your ductwork, we can get an idea of precisely what is going wrong during the air distribution process.

Clearly, the placement of your ductwork throughout your home makes it impossible to thoroughly visually inspect it. The technicians at Cal-West Air Conditioning, though, have the tools and training necessary to ascertain precisely what kind of condition your air ducts are in.

Schedule your air duct testing services in San Diego with us so that you can find out definitively what must be done to get your system back on track.

Why Professionals Must Complete Your AC System Installation

March 20th, 2015

Investing in a great air conditioning system is a good way to ensure that you are able to live with the comfort that you desire during the hot, sunny summers we enjoy around here. However, you must remember that no AC is going to excel and live up to its full potential if not properly installed in your home. To get the most from your air conditioner, you absolutely must schedule your AC system installation in San Diego with a skilled, qualified technician. That is as simple as dialing our number. When you hire Cal-West Air Conditioning to complete your AC installation you can count on the job being completed properly every step of the way.

The reasons for scheduling your AC system installation with an experienced professional are many. First of all, working with a pro is the best way in which to ensure that you decide upon the best air conditioner for your unique needs. There are a number of different cooling systems available on the market today. All have their own pros and cons, and it can be difficult to ascertain which best suits your cooling habits. We’ll make sure that you have the air conditioner that best fits the bill.

Once you’ve carefully chosen your air conditioner, it is vital to ensure that your specific unit is of the right size for your home. The last thing that you want to do is to spend the money on a brand new whole-house cooling system, only to find that it is too small to cool your home effectively or efficiently. Of course, bigger is not always better in this particular instance. If your system is oversized, then it will adjust temperatures too rapidly. This may sound like an odd concern, but it can result in decreased indoor air quality, as well as short cycling which can put a lot of unnecessary strain on your system.

Finally, there is the design of the system’s ductwork, when applicable, the mounting of thermostats, and all of the other nuts and bolts of the physical installation itself. This is a whole lot to consider, and only trained professionals have the knowledge necessary to guarantee that each and every component in your system is successfully integrated into your home.
