Importance of Air Conditioning Maintenance

Get peace of mind with regular air conditioner maintenance from Purl’s Sheet Metal & Air Conditioning.

As spring approaches, it’s time to think about getting your HVAC system ready for the summer. It’s been months since most of us have used our air conditioner. Finding out the air conditioner in your home does not work during the first heat wave can be a big problem. Below are some of the important reasons why routine scheduled maintenance will help get your Air Conditioning system serviced and ready for summer.

Replacing the Air Filter

Forgetting to change the air filter can cause big problems for your HVAC system. When the air filter is clogged, it means that the air conditioner has to work harder to move air throughout your home. The harder your air conditioner has to work it could cause stress to your system and lead to costly breakdowns. There are many options to update your filters and improve your indoor air quality.

Unclogging the AC Drains

It’s easy to see the problems from clogged drains in the sinks and showers in your home. It is much harder to see the problems from a clogged AC drain.  Often by the time you see evidence of a clogged AC drain in your home it has led to damage. A professional HVAC technician will make sure the drain is clean and flowing smoothly.

Cleaning the Air Conditioning coils

Cleaning the condenser coils is an important part of maintenance. A qualified service technician will clean the dirt and debris from the coils and this will help your system operate more efficiently.

Checking the Thermostat

It’s a good idea to check the batteries, programming and operation of your thermostat each season. A thermostat problem can be a direct cause of a cooling issue.

Schedule a certified HVAC Professional

Be sure to schedule maintenance for your air conditioner with a professional and qualified service technician at Purl’s Sheet Metal & Air Conditioning. Maintenance and tune up’s will increase the life of your equipment, find potential break downs and make sure your air conditioner runs efficiently so you are ready for the hot summer temperatures.

The Wrong High-Efficiency Air Filter Might Spell Disaster for Your HVAC System!

Tuesday, July 17th, 2018

pleated-air-filterAlmost any modern home can benefit from air cleaners of some type. Indoor air quality is often poor because homes are built today to seal out the heat in summer and seal it in during winter—and that means not much fresh air circulation.

What type of air cleaner is best for a home? There are plenty of options, and our IAQ experts at Purls Sheet Metal and Air Conditioning are happy to help you find the best. In most cases, improving air quality starts with putting in filters and then finding what other devices might help. Filters are almost always a good idea…

…except when the wrong type of filter goes in. When it comes to high-efficiency filters, such as the HEPA filter, you can have too much of a good thing. Too strong a filter can damage your HVAC system.

Improving Indoor Air Quality and Improving Your Family’s Health

Monday, June 27th, 2016

Because of concerns about air pollution from industrial sources, people often tend to think of poor air quality as something that only exists outdoors. But this isn’t true. A report by the Environmental Protection Agency has discovered that the air inside commercial and residential buildings is often three to four times worse than the air outside. The reason for this is the high number of contaminants and pollutants that become trapped inside a building because there is so little fresh air moving through them.

What Kind of Air Filter Do I Need to Clean My Home’s Air?

Monday, June 8th, 2015

If your home has a forced-air heater or central air conditioning system, then it is probably equipped with a filter located near the air handler. This filter consists of a mesh of fibers that traps contaminants coming in through the return air ducts, preventing them from entering the AC’s cabinet. This filter is designed to protect your air conditioner, which is an important job. But it is not designed to protect the quality of the air circulating through your house. If your home is suffering from an excessive amount of airborne pollutants that are triggering asthma and allergy symptoms among the people who live there, you need to have special filters or air purifiers installed.

Problems Caused by Dirty Air Filters

Friday, June 27th, 2014

air filters, old and newEvery air conditioner has an air filer, deigned to catch particles of dirt and dust and keep them from moving through the system. Air filters need to be changed periodically (though some models have reusable filters that can be washed instead of being replaced) or else they can cause a considerable number of problems. Here in Fresno, air conditioning services can usually treat the problems cause by dirty air filters, but the more you know about the issue, the better you can prevent such problems from starting in the first place. Call us today if you need your air filter replaced in Fresno.

Dirty air filters tend to clog the flow of air through the system, which means your air conditioner needs to work harder in order to do its job. Not only does this increase strain on the entire system (raising the risk of repairs), but it forces your AC unit to expend more energy, which results in higher monthly bills. In addition, the excess dirt blown through the system will spread throughout your household via the air ducts. If you have sensitive family members, such as the elderly or those suffering from asthma, this can constitute a health risk, and even in healthier family members, the excess dust can result in a scratchy, irritated throat and lungs.

On top of that, the excess dust can coat the inside components of your air conditioning system itself. This can create friction in moving parts, increasing the overall wear and tear and raising the chances of a more serious breakdown in the future. It can also create ice on the evaporator coils, clog lines and other key components, and cause no end of slow, long-term damage over time.

You can reduce the risk of problems caused by dirty air filters by having them changed regularly, ideally as part of a larger maintenance session from the experts at Purl’s Sheet Metal & Air Conditioning. We have the skills you need to do the job right, and we can help you stop a number of issues before they start.

Here in Fresno, air conditioning systems are an absolute necessity during the heat of summer. Give us a call today and let us make sure it’s ready when you need it!

Summer Air Conditioner Start Up Tips

Wednesday, April 30th, 2014

Summservice pageer temperatures have arrived Fresno, CA and the Central Valley. Many people will be turning on their AC for the first time in the next few days as temperatures are expected to reach the mid 90’s for the first time this season. Here are a couple of tips to help keep you cool and to get your HVAC system ready for the summer months.

Replace air filters

It is a good idea to replace your air filters at the start of the cooling season. This will help your cooling system to operate at peak condition. (Filters should be changed every 3 months).

Service System Regularly

Servicing your home’s heating and cooling system is as important as changing the oil in your car. Schedule a seasonal service appointment to have your unit checked and cleaned for the summer season. Efficiency decreases when the system is dirty. Service Technicians will also check your condensate line to make sure it is draining properly. A clogged and dirty condensate drain can cause water damage to your home.

Program Thermostat

Program your thermostat for the summer season. Avoid making large thermostat adjustments during peak cooling times. If you turn your system completely off it can take many hours to bring the indoor temperature back down to your comfort level. Set your thermostat to 78 or whatever is comfortable while you are home and raise the temperature level while you are away.

Visual inspection of your system

Remove any debris or plant growth from outdoor condensing units. Make sure any outdoor winter covers are removed before turning on your unit. Keep area around units clean

Check to make sure all vents are open

Make sure all of the supply vents in the home are open for cooling.

Test your system

Turn on your HVAC system and let it run for about an hour. Make sure the vents are blowing cold air. If Heating Pagethe vents are blowing warm or hot air you may need refrigerant for your system. You can damage the cooling system components if you operate the system when it is low on refrigerant. Contact Purl’s Sheet Metal & Air Conditioning to schedule a service appointment in Madera or Fresno, CA.

It is a good idea to do a visual inspection and to run your HVAC system through a test cycle at the beginning of every season. It is also recommended to have your system serviced routinely to keep it clean and to spot any possible problems before they lead to an unexpected breakdown. Call Purl’s Sheet Metal & Air Conditioning to schedule an appointment with one of our service technicians today.

Replacing Air Filters on a Regular Basis

Thursday, January 30th, 2014

Purls - Filters-2

Replacing the air filters regularly in your home or business is a must.   A clogged air filter can cause trouble with your HVAC system.  It can cause additional stress to your heating and cooling equipment that can lead to costly breakdowns or even equipment failure.  This can lower the indoor air quality of the air you breathe.  The air filters need to be changed on a regular basis or it can block and restrict air flow through your ductwork and HVAC system.


Your AC system is designed to remove heat from your home or business.   The fan pulls the warm air and passes it over evaporative coils.  The fan pushes the newly generated cool air through the ductwork system to cool your home or business.   When the filter is clogged it reduces the airflow into the system and can cause many problems.   It can reduce the cooling capacity and in turn reduce the comfort level.   It can even cause the coils to ice up and the system to struggle and make noises.  During the hot summers in Fresno CA, you want to make sure your equipment is working to capacity.  Poor operation can reduce the efficiency and lifespan of your equipment not to mention your comfort level.


Operating your heater with a clogged filter can be very dangerous.   A clogged filter does not allow enough cold air to pass over the heat exchanger and can cause the heat exchanger to crack.   When a heat exchanger cracks it can be dangerous.   It can leak carbon monoxide into your home or business.

Just like your car, your home’s heating and air conditioning system needs regular maintenance and service to keep it running properly.   Check your operation manual for the suggested filter changing requirements.  The best way to extend the life of your equipment is to have your HVAC system serviced, cleaned and inspected on a regular basis by a licensed professional.  During routine service your technician will replace the air filters and clean the components of your HVAC Air Filter.   At Purl’s Sheet Metal & Air Conditioning our service technicians can service your HVAC system, change your filters and help you maintain efficient operations.
