Why You Need to Have Your Air Conditioning Checked Before Summer Starts

Monday, March 30th, 2015

There’s a pretty wide variance in the way people treat their air conditioning systems.

Some people just install them, hope for the best, and only call for repairs when the entire system breaks down. Some people make sure to pay close attention to the way their air conditioner behaves, so they can catch problems before they have a chance to extensively damage the system.Finally, some people supplement their vigilance with regular professional maintenance. If you aren’t part of the last group, you should be.

Let’s take a look at why you need to have your air conditioning checked before summer starts.

Cost Benefit Analysis

The main reason that people avoid scheduling preventive maintenance for their air conditioners is that they don’t believe it’s necessary. Why spend the money to have a professional check out the system if there’s nothing wrong with it? The flaw in that line of reasoning is that, while there may not be anything apparently wrong with your system, there could be plenty of developing problems inside it that aren’t outwardly visible. Not all air conditioning problems have obvious symptoms. Usually, the only way to identify these problems is to physically check the part that’s starting to malfunction. Preventive maintenance is the only way to identify and fix these issues before they have the chance to get any worse.

Why Spring Maintenance?

If a system does have any problems or vulnerabilities, they are most likely to be brought out by increased stress. Summer is the time when your air conditioner sees the most use, which makes it the time when your system is most likely to break down. Spring maintenance is a way to make sure that your air conditioner is in top operating condition, right before it is put under the most stress. Now is the time to make sure that your air conditioner is up to the task of keeping you cool all summer.

If you haven’t had preventive maintenance done on your air conditioner this year, call Roznovak. We provide air conditioning maintenance throughout the Round Rock area.

The Benefits of Commercial Duct Cleaning

Tuesday, March 24th, 2015

Ducts are an important part of any centralized forced air system. This is especially true for commercial HVAC systems, which employ much larger and more complex ductwork than residential properties do.

The ductwork in your building is responsible for keeping you and your employees comfortable, by transporting fresh air from your heating and air conditioning systems. Unfortunately, ductwork can also harm those inside a commercial property if it is not properly maintained.

Let’s take a look at one of the harms that can occur due to poorly maintained ductwork, and what you can do to prevent it.

Airborne Contaminants

The air inside the average commercial building is infested with millions upon millions of microscopic airborne contaminants. Things like viruses, bacteria, dust, mold spores, and insect dander are all commonly found floating through the air in commercial and residential buildings. These contaminants tend to be pretty loosely dispersed, which prevents them from having any serious health effects on those in the building.

In the ducts, however, these contaminants are given a safe haven in which to gather. The level of pollutants builds up in your ducts over time until a forced air system is turned on, at which point the entire building receives a concentrated blast of them. This makes it more likely for the building’s occupants to suffer allergy attacks and illness.

Duct Cleaning

In order to address these contaminants, it’s a good idea to schedule commercial duct cleaning for your building at least once every one or two years. Duct cleaning is where your HVAC company removes any and all contaminants that may be lurking in your ducts, either through vacuums or manual cleaning or both. Duct cleaning significantly improves the indoor air quality of your business, thereby improving the health and quality of life of everyone inside.

It can also improve the efficiency of your HVAC system, by revealing any leaks or other issues that need to be dealt with. If your ducts haven’t been cleaned in a while, you could most certainly benefit from scheduling a duct cleaning today.

How to Avoid the Need for AC Repair

Wednesday, March 18th, 2015

Our days are warming up, and many of you may have already turned on your air conditioning systems to help stave off the early spring heat. We use our air conditioners for a lot of the year, so taking some steps that can help you avoid the need for A/C repair in Austin is always a good thing for our local homeowners.

We’ll outline more of these steps below, but if you are experiencing any issues with your air conditioning, call the people you can count on: Roznovak.

Step 1: Don’t Ignore Strange Sounds

Let’s be honest: no homeowner looks forward to air conditioning repair. But ignoring strange sounds or poor performance doesn’t make the problems go away, and will most likely make the problems worse. And just because your system is still operational doesn’t mean that there isn’t a problem; it just means the problem hasn’t become serious enough yet to result in breakdown. So what kinds of noises are we talking about? Buzzing, banging, popping, really anything that sounds of the ordinary. When you hear anything strange, call for help.

Step 2: Change the Air Filter

As far as individual components go, your AC’s air filter is probably one of the least complicated ones in the entire system – but that doesn’t mean it can’t cause problems. A clogged air filter can seriously restrict the air flow in your entire system, causing any number of systemic problems to develop. But there’s an easy solution to this: change the air filter every 3 months. Replacing your air filter every quarter helps keep your AC healthy and eliminates the problems that can develop from a clogged air filter.

Step 3: Schedule Annual Maintenance

Maintenance is a full tune-up for your air conditioner, and spring is the perfect time to schedule it. Why schedule maintenance? During a maintenance appointment, your system is thoroughly inspected, components are cleaned and adjusted, and all moving parts are lubricated. The technician will also test for performance, and if any existing or developing problems are found, you’ll be alerted. Maintenance helps keep your system in good working order for the whole cooling season.

Signs That You Need Air Conditioning Repair

Tuesday, March 10th, 2015

Air conditioner problems are a bit harder to diagnose than heater problems, at least for the untrained eye. There are a few symptoms that cross over. Lack of heating/cool air is a pretty obvious sign of trouble, for example. However, there are a lot of problem indicators that are specific to air conditioners. So, if you want to keep your air conditioner in good condition it’s a good idea to learn these unique indicators. Let’s take a look at some of them.

Ice

TechWithCondensorAir conditioners are supposed to keep your home cool, but there are limits to how much they can lower the temperature and still operate correctly. If you see ice on your air conditioner, it’s a sign that something has gone wrong. This can be caused by dirt on the coils or a low refrigerant level, both of which can lower the temperature below what it should be.

Once the ice has formed, it prevents the coils in the air conditioner from successfully drawing heat from the air. This causes your air conditioner to actually lose cooling ability, and can damage the coils on top of that. So, if you see ice forming on your AC, call for repairs.

Short-Cycling

Short-cycling is when your air conditioner keeps rapidly turning itself on and off during operation. This is an extremely harmful effect that can be caused by a few different factors. The compressor could be malfunctioning, which results in irregular pressure in the refrigerant line. The problem could also be located in the thermostat, which may have a faulty temperature sensor. Regardless of the cause, however, the behavior itself places the air conditioner under an extreme amount of stress. If the cause isn’t found and treated by a professional, you may have to replace part or all of the system.

Air conditioning repair is a broad topic, and not one that we can entirely cover in this post. If you suspect that your air conditioner might be malfunctioning for any reason, call Roznovak today. We offer air conditioning repair services throughout Austin, TX.
