Why is My Air Conditioner Cycling On and Off Frequently?

Sunday, August 18th, 2019

Air conditioning is essential when you live in Las Vegas, Nevada. One of the more common issues that can cause an air conditioner to malfunction is short cycling. This is when an air conditioner switches off and on repeatedly before completing its cooling cycle. Fortunately, this issue is repairable. Here’s everything you need to know about short cycling, including what to do when it happens. And if your system is older and struggling with frequent breakdowns, you may want to consider why fall is the best time to replace your AC unit.

Why your AC is short‑cycling?

  • Check the air filter — If it’s clogged or dirty, airflow drops and the unit may overheat and shut off prematurely.
  • Inspect the thermostat — A faulty or miscalibrated thermostat can trigger frequent on/off cycles.
  • Verify refrigerant levels — Low refrigerant causes overheating and automatic shutdowns to protect the system.
  • Electrical issues — Problems with the electrical board or control wiring can cause erratic cycling. 
  • Call HVAC repair service — If basic checks don’t fix the issue, a technician should diagnose more complex problems to prevent damage and prolong system life.

Why is My Air Conditioner Short Cycling?

Short cycling is generally caused by common issues a professional service technician can repair easily. The thermostat, which regulates temperature and tells your air conditioner when to turn on and off, might need replacing. Or, the air filter has clogged. This prevents the filter from drawing in enough air, causing it to overheat and switch off. If your AC unit’s refrigerant levels are low, it might turn itself off to avoid overheating, as well. Further, a malfunctioning electrical board can cause an air conditioner to turn on and off at improper times. In some cases, these warning signs are just another example of how an AC repair can sneak up on you.

Why Short Cycling is Bad

An air conditioner that short cycles requires professional repair or maintenance. If you choose to ignore the problem, it’ll get worse. As a result, it’ll reduce your air conditioner’s lifespan in the process. This is due to the excessive strain short cycling puts on the unit’s fans, bearings and other components.

What to Do About Short Cycling

First, check your air filter and replace it if it’s excessively dirty. If this doesn’t fix the problem, a clogged filter isn’t to blame. In this case, the resolution is probably not going to be a quick, do-it-yourself fix. You’ll need to have your unit repaired by a professional as soon as possible to avoid causing further damage. We can diagnose and repair the problem quickly, leaving you free to relax and enjoy your air conditioning again. To reduce the chances of this happening next season, it’s a good idea to add AC maintenance to your spring checklist.

Don’t put up with an air conditioner that isn’t working properly. Call Johnny On The Spot at (725) 977-9461 for help solving your short cycling problems.

All You Need to Know About Ductless AC Units

Friday, March 16th, 2018

If you’re in the process of remodeling or adding on to your Summerlin, NV, home, then you are likely thinking of ways to make your home more comfortable without breaking the bank. A ductless AC unit could go a long way toward giving you the energy-saving and comfort benefits you seek. Ductless AC units offer many benefits that their ducted partner cannot—like greater control and improved indoor air quality.

Get in the Zone for Comfort

Flexibility is a significant advantage of ductless AC units or ductless mini-split systems. These units consist of an indoor component that connects to an outdoor compressor via a narrow tube. This design, and the fact that they do not use ducts mean you can easily install them in any room. You can choose single-zone or multi-zone systems.

Each unit comes with a remote control, so persons can set the temperature they prefer in their area or zone. You put an end to thermostat wars with this customization, and you can also activate the system only when needed, so you save energy. Occupants can customize heating and cooling without changing the temperature throughout the house.

Great for Indoor Air Quality

The absence of ductwork means you eliminate the problem of debris collecting in ducts and then circulating through rooms in your home or building. Ductless mini-splits have multi-stage filtration that removes dust, pollen and other contaminants.

Their design also makes cleaning and maintenance easy. Don’t let the IAQ advantage go to waste by neglecting to schedule seasonal tuneup for your ductless AC.

Energy and Cost Efficient

You save energy with a ductless AC. According to the U.S. Department of Energy, a ductless mini-split uses 60% less energy than standard electric home heating systems. This is because they transfer rather than, generate heat. Similarly, in cooling mode, you can reduce cooling costs by 30% compared to conventional ACs. Their compressors and fans adjust speeds, so you save energy.

If you’re thinking about upgrading or adding to your home, then maybe you should give ductless AC units some serious consideration. If you would like to learn more about these systems, call Johnny On The Spot today at(725) 977-9461.

5 Questions To Consider When Buying An HVAC System

Monday, October 2nd, 2017

Before purchasing a new HVAC system, what should you consider? HVAC installation means choosing the right size and the right system for your home, then coordinating with your contractor on installation timing and ongoing maintenance. For Las Vegas homeowners, that decision is shaped by the desert climate, where proper sizing and system selection affect comfort, energy efficiency, monthly costs, and how long the equipment lasts.

If you’re planning to buy and install a residential HVAC system, these are the questions to ask before you commit. You’ll learn how to compare unit types, determine the right HVAC size, understand how long installation can take, review available incentives, and see why a maintenance program matters after the work is done.

What Size Is Best For My Home?

The first thing that you should consider is the compatibility of your ac unit size with the area of your house where it will be installed. Inappropriate size can cause your HVAC unit to function inefficiently or produce trouble instead of comfort. For Las Vegas homeowners in a desert climate, choosing the right air conditioning system starts with matching capacity to the home rather than guessing. If you have a small room, a small air conditioner will suffice. Likewise, larger rooms require larger HVAC units.

When a small air conditioner is installed in a large room, the system will work hard to meet your desired room temperature. The double effort causes the system to consume more energy which can result in higher monthly utility bills. And if you install a large HVAC in a small room, it won’t run as often as it should, resulting in high humidity levels. High humidity in the air produces mold and mildew which are hazardous to our health and a threat to our home’s interior.

What Type Of Air Conditioning Unit Do You Recommend?

This question is something you should ask your HVAC contractor. The type of unit will vary depending on the design or style and size of your home. Size should be based on your home’s square footage, sun exposure, current setup, and existing ductwork rather than room size alone. Discuss with your contractor whether a split type or packaged HVAC unit is advisable, how the indoor and outdoor units will fit your layout, how much space is available, and whether the noise level matches your comfort preferences. Tackle your options with them and ask for their recommendations on the right air conditioning system for your home, especially since planning an HVAC installation in Las Vegas requires attention to extreme desert climate and can affect which air conditioning system is the best fit. A Manual J load calculation helps determine the correct size for a new air conditioner.

Aside from the unit, considering the efficiency rating of the HVAC is also important. Make sure the new ac is sized properly for your home, because an oversized unit can leave uneven temperatures indoors, will not dehumidify properly, and will cycle too often. Improper sizing can reduce system efficiency by up to 30% and raise energy costs. The cooling system’s efficiency rating is referred to as Seasonal Energy Efficiency Ratio (SEER), and higher seer ratings mean a more efficient air conditioning system. In the Southwest, the federal minimum SEER2 is around 15 or 16, while high efficiency systems often start at 16 or higher. If your budget allows, ask about high efficiency units and other equipment, since a new system with stronger ratings can deliver lower utility bills over time. The heating system’s efficiency is expressed in Heating Season Performance Factor (HSPF). Lastly, the furnace efficiency rating is called Annual Fuel Utilization Efficiency (AFUE). Inspecting and sealing ductwork helps prevent poor airflow and supports a new system’s efficiency.

How Long Is The Installation Process?

Your HVAC contractor will provide you a contract that outlines the hvac installation process, including the start date and expected completion date for the project. Before work begins, the recommendation should account for the air conditioning system design, including whether the indoor and outdoor units fit the home and available space. Licensed contractors must obtain the necessary permits before installation, and permits are required for replacement work in Clark County and Las Vegas so this step ensures code compliance with local building codes and a smoother inspection. Make sure you are knowledgeable about the length of days it will take for the installation’s completion, and confirm site access such as gate codes, parking, and clear entry. Most jobs for hvac installation take one day to complete, though timing can vary based on the system and site conditions. It will help you avoid any unnecessary extra charges for the service.

Some homeowners also compare noise level when choosing a new air conditioner or new system.

For every specific unit, replacing an old system may involve removing old equipment, safely disconnecting the old system, recovering refrigerants, and handling disposal according to EPA rules before the new air conditioning system is set in place. Your selected model will influence the costs and time period for the installation. A new electrical connections or an electrical panel upgrade may also be needed, and electrical wiring must be handled by licensed professionals for proper installation. A higher SEER rating indicates a more energy-efficient air conditioner. High-efficiency systems often start around SEER 16 or higher, while the federal minimum SEER2 for the Southwest region is about 15 or 16. ENERGY STAR-rated equipment is also worth considering because it can reduce long-term utility bills even if the upfront cost is higher. A final walkthrough and final inspection confirm operation, answer homeowner questions, and verify the system meets local codes.

Does The Model Have Incentives?

A lot of energy-efficient models come with manufacturer rebates, which can lower the upfront cost. These rebates will help you save money and may also reduce long-term energy costs. You can ask your HVAC contractor about mail-in rebates, especially on high-efficiency systems that can help cut energy bills. You can also do some research to see if you qualify for any tax credits, and professional installation helps protect manufacturer warranties while DIY work can void warranty coverage.

Do They Offer A Maintenance Program?

Investing in a preventive HVAC maintenance program not only helps you save money but also keeps your HVAC system efficiently working throughout its lifespan. It only makes practical and financial sense to apply for an HVAC maintenance plan with the HVAC contractor who will perform the installation process, since licensed HVAC contractors help ensure compliance with local building codes and handle permit documentation tied to the original installation. It will help you build a positive working relationship with the company and its technicians since they will be familiar with your home’s structure and history better than anyone else. Incentives can also help offset the upfront cost of different system types, from central AC and heat pumps to ductless and geothermal options. Representative costs often range from $3,000 to $15,000 for central AC, $6,000 to $25,000 for heat pumps, $2,000 to $10,500 for ductless mini splits, $3,800 to $12,000 for gas furnaces, and $12,000 to $45,000 for geothermal heat pumps. High-efficiency units may cost more at first, but they can lower monthly utility bills and overall energy costs over time, especially when you are installing a new ac system in a hot climate. ENERGY STAR-rated models and Nevada standards aligned with the IECC can also affect rebate eligibility and long-term value.

When you apply for a maintenance program, an HVAC technician will come into your house at least twice a year to evaluate your system’s efficiency and conduct any minor repair when necessary. Technicians also use the necessary tools and wear protective equipment when handling HVAC components. If you smell gas or smoke, stop work and call authorities instead of inspecting the equipment yourself. Regular service can also catch poor airflow, strange noises, and frequent breakdowns before they turn into bigger problems or lead to AC repair needs.

Your HVAC system is a lifetime investment. Therefore, you should make careful decisions, rough estimates and conduct some researchers before you engage in purchases. Knowledge from HVAC contractors can also help you make the right decisions in buying an HVAC unit since they will provide you with helpful tips and suggestions. Working with licensed professionals and certified technicians also supports professional installation, helps protect manufacturer warranties and warranty coverage, and gives you a clear path to air conditioning installation services with an in home consultation and a free estimate; they must also obtain permits before work begins, and proper setup can help keep las vegas homes home cool while supporting home resale value.

5 Ways To Keep Your Las Vegas Home Cool For Less

Wednesday, June 14th, 2017

Summer tends to get really hot especially in Las Vegas. It is the time that you make use of your cooling system to get rid of the heat. However, cooling your house doesn’t have to be expensive. There are smart yet efficient ways to save yourself from high energy bill while enjoying the comfort of a cool air surrounding your house.

Want to find out how? Check out below.

Upgrade Your Thermostat

Using a programmable thermostat can help you save on your energy bills a lot. The greatest advantage of a programmable thermostat is that it only functions when you are home. If you are gone to work, for example, it will automatically shut the AC down thus, saving you from the worry that you have forgotten to turn your AC off upon leaving home.

Control Humidity

Another important thing you should consider is regulating the humidity inside your house. Whenever you are running your conditioner, make sure that you are not using any appliances that emit too much heat. For example, avoid using the oven, flat iron, washer or dryer. The presence of additional heat within your home will make it harder for your AC to cool the air. The harder it works the more energy it consumes.

Keep the Air Circulating

If you think ceiling fans are a substitute for air conditioners, then you are wrong. In fact, you should run it together with your AC unit. The presence of the ceiling fan will help circulate the air inside your home. This will make cooling your home faster over a shorter period of time. The faster your inside temperature cools down, the less hard work it is for your AC to cool your home’s atmosphere.

Insulate Your House

When we say insulate, we refer to heat-proofing your house. Not allowing heat to enter your house or letting cool air escape from your house will be easier for your air conditioner to reach its desired temperature. Make sure to cover any unnecessary holes. Use shades or draperies to cover your windows to block off heat especially during summer.

Don’t Forget the Maintenance

Maintenance is vital to our AC units in order for it to run efficiently for a long time. A well-maintained air conditioner can last up to a maximum of fifteen years! Do regular monthly maintenance like changing or cleaning your filters, cleaning your coils, making sure your outdoor unit is free from debris, and have your trusted technician conduct seasonal maintenance.

Try applying these smart yet effective tips in your home and observe the changes in your monthly energy bills. You’d be surprised at how these simple steps can drop the price of your utility bills.
