The term short-cycling refers to when the compressor of an air conditioning system turns on and off rapidly, never getting a chance to complete its full cooling cycle. A short-cycling air conditioner is a serious problem for a number of reasons: The extra stress placed on the components will lead to multiple repair needs. The strain can cause the compressor to break down, which often requires that the whole system be replaced. And because air conditioners draw the most power when the compressor starts up, a short-cycling AC will create a large increase in electrical bills.

3 Reasons Why Your Air Conditioning Is Short-Cycling
Wednesday, June 3rd, 2015An Oversized Air Conditioner: Why This Is a Problem
Tuesday, May 26th, 2015When you need a central air conditioning system installed, whether for a new home or to replace an older system, you must call professionals to handle the work. This is not only to ensure that the new air conditioning system is put in correctly so that it works at maximum efficiency and effectiveness. It is also to make sure that the right system is put in. An error in sizing a central air conditioner (i.e. determining how powerful an AC is necessary for a specific home) will lead to multiple problems for both comfort and energy efficiency. In most cases, an improperly sized air conditioning system must be replaced.
What the Condensing Unit Does in a Central Air Conditioning System
Monday, May 18th, 2015The standard central air conditioning system found in homes is a split system: it consists of two units housed in different locations that are connected through power and refrigerant lines. The indoor unit contains the evaporator coil and the air handler that sends cooled air into the ductwork and then to the rooms. The outdoor unit is called the condenser.
3 Common Misunderstandings about Air Conditioning Systems
Monday, May 11th, 2015Air conditioning systems are such a standard part of life during the summer—especially in a place that grows as hot as the Central Valley—that it’s easy to take them for granted. This is one of the reasons that there are so many myths and misunderstandings about air conditioners that continue to spread. Below are three common ones we wish to dispel:
Air Conditioning Question: What Does Refrigerant Do?
Monday, May 4th, 2015Modern air conditioning systems are complicated machines that require a balance of components working in peak condition: the compressor, fans, coils, capacitors, motors, etc. All of these parts play vital roles in providing a home with cool temperatures. If one of the parts starts to fail, it can mean a drastic drop in efficiency and effectiveness.
Spring Is the Right Time for Air Conditioning Installation
Friday, April 10th, 2015Spring is the season when homeowners should schedule professional maintenance for their air conditioning systems to make sure they are ready to handle the summer weather. It is also the ideal time for homeowners to install new air conditioners if their current ones have doubtful futures.
If you are considering replacing the aging air conditioning system in your home, now is an excellent time to have the work done—even if your current AC is still performing at an “adequate” level. You can contact Purl’s Sheet Metal & Air Conditioning to arrange for regular maintenance that will help you decide if it is time for new air conditioning installation in Fresno, CA. We will help you pick the best model to suit your cooling needs and have it installed quickly. You will then be ready to take on whatever temperatures the summer might send your way.
One of the reasons that it is a wise idea to arrange for air conditioning installation during the spring is that scheduling the work is easier. Spring is a slower time of the year for HVAC professionals: they are not busy with winter heating system repairs or responding to calls for summer air conditioning emergencies. Technicians spend this season helping homeowners get ready for the summer heat with maintenance services and new installations. When you arrange for a new air conditioning installation during the spring, you should have few problems scheduling a time that is convenient both for you and your contractor.
Spring installation will also see that your house is ready ahead of the worst heat waves. Delaying with putting in a new air conditioner only increases the chances that your current system will have to turn on to cope with a hot day—only to finally break down. It is better to play it safe and have the ailing AC replaced before the arrival of summer. Your new air conditioner’s superior energy efficiency will also see that you start saving money right away.

Some Air Conditioning System Warnings Signs to Watch for in the Spring
Monday, April 6th, 2015Spring is the season when you should arrange for professional air conditioning maintenance. This service will see that your home’s AC is cleaned, tuned-up, and any potential malfunctions caught before they become serious problems. Annual spring maintenance is the best way to protect your home comfort through the summer.
But even with the best maintenance possible for your air conditioning system, you must pay special attention to warning signs from it during these early spring days. Odd behavior can point to developing faults that may lead to an inefficient cooling system or even repairs down the road. If you notice any of the following from your air conditioner while it is running during the spring, give the professional service technicians at Purl’s Sheet Metal & Air Conditioning a call right away. Our expert team is ready 7 days a week to look into any problem with your air conditioning system.
- Out of the ordinary noises: You probably have a good idea of the sounds that your air conditioner makes while it’s running normally. When something that doesn’t sound right interrupts this regular series of sounds—such as mechanical grinding, hissing, or clicking noises—it probably means something is wrong with the AC that needs attention.
- Ice on the indoor coils: Although ice may seem like something normal for a system that sends out cold air, it isn’t. If the indoor coils of your AC begin to develop frost, one of a number of problems is affecting the system, and all of them are serious. Get service technicians on the job right away for repairs.
- Odd smells from the vents: If you notice acrid, musty, or moldy scents coming from the air vents, don’t hesitate to contact HVAC professionals to look into it. This could indicate a motor that is overheating, or it may point toward ductwork damage that will require repair work from ventilation specialists.
It’s crucial that you never ignore unusual behavior from your air conditioning system. These aren’t “quirks”: they are the way that your AC warns you it requires the service of professionals.

Ways Faulty Ductwork Can Affect Air Conditioning
Friday, September 19th, 2014Not all the trouble that can plague an air conditioning system comes from inside the AC cabinets. Often, a faulty thermostat can cause a cooling system to work incorrectly. Another common source of air conditioner problems are faults in the ductwork connected to it, such as air leaks and breaks.
It is often difficult to tell the source of a malfunction in an AC if you are not a trained technician. Don’t attempt to guess at what has gone wrong when your air conditioner starts to lose its cooling ability, generate strange noises, or show other signs of working incorrectly. Call on HVAC experts to look into the problem, locate the source, and fix it.
Purl’s Sheet Metal & Air Conditioning has served the Central Valley since 1952. If your air conditioning system is suffering from problems due to faulty ductwork, you can trust to our team to handle the necessary repairs and duct sealing to restore your cooling.
How Faulty Ductwork Impairs an Air Conditioning System
Well-designed ventilation systems are airtight. This prevents loss of air pressure as the conditioned air from the AC moves toward the vents. Even a small leak along the ductwork can cause a drop in air pressure that will lower the airflow from the vents and lead to a loss of cooling in the rooms.
As an air conditioner loses air pressure because of faulty ducts, it will also start to work harder in order to maintain its target temperature. This places extra strain on the system, which increases the chances of it malfunctioning. The increased stress level on the mechanical components will also make the air conditioning system age faster and possibly need premature replacement.
Breaks along ducts often permit outside contaminants into the ventilation system, and subsequently into the AC. Even if this extra dust and dirt gets caught in the system’s air filter, the filter will rapidly clog up to the point that it will cause a large increase in the strain on the air conditioner. Clogged filters may also lead to ice developing along the indoor evaporator coil.

Friday, September 12th, 2014It may seem early to talk about readying your HVAC system for fall and winter, especially when your air conditioning may still be running, but in a few short weeks our temperatures will be significantly cooler. Preparing your HVAC system for winter now can get you ahead of potential problems without disrupting your household. Since 1952, Purl’s Sheet Metal & Air Conditioning has helped multiple customers prep their HVAC systems for the coming season, and we can help you, too.

Benefits of a Packaged Unit
Friday, September 5th, 2014If you’re in the market for a new air conditioning system, there are many efficient options available, and a technician can help you find the right choice for you depending on your home and lifestyle. Here at Purl’s Sheet Metal & Air Conditioning, we want to help you learn about the different types of air conditioning systems so you can decide which one is right for your home. In this guide, we will discuss the benefits of packaged air conditioning systems, an alternative to the traditional split-system air conditioner.
There are two types of HVAC systems that are currently used. Split systems have components separated with the condensing unit outside the home and the furnace and evaporative coil inside the home, attic, or possibly the garage. A packaged unit has all the components packaged together, and it is typically mounted outside on the roof or on the ground.
Space
While split-system air conditioners are the most common systems found in homes, some unique home designs do not have the space for installation of an indoor unit. In this case, a packaged unit is often the best option. Because your packaged unit will be connected directly to the ductwork of your home, there is no need for indoor installation. Furthermore, the cabinet may be located on the rooftop, saving space outdoors as well.
Accessibility
Because all of the parts of the system are located in a single cabinet, packaged systems are easily accessible. If you need repairs or if you schedule maintenance, a technician can access your system without moving back and forth between units, as every part is in one location. And because a packaged unit is often located on the rooftop, the technician stays out of your way, so your daily life can continue as usual while you wait for repairs or maintenance to be completed.
Packaged units are just one of the options for air conditioning in Fresno available from Purl’s Sheet Metal & Air Conditioning. Call us today to talk to an expert about the best option for your home.
