What Should You Know Before You Choose a Residential AC Repair Company?

It can be very stressful when you find out that you need a residential AC repair company. You might need a repair, or you might need a replacement. A qualified repair company can give you the information you need. You need to do your research and ask different questions to determine if the company is for you and can handle your project. Here are a few different things you should know before you choose a residential AC repair company.

  • License – Make sure the AC repair company is licensed and insured (bonded) in your area. This means they have to abide by certain standards and are more reliable. The insurance is there to protect you in case something happens, like an injury, on your property, to the worker when they are installing or repairing your air conditioning system. Any company that has these things should be able to give you a copy of their documentation. You need to make sure they actually have them so that you are protected.
  • Experience – You want to find someone who has been doing air conditioning repair for a decent amount of time. While it is great to give a new business a chance, when it comes to air conditioning repair, you want someone who has proven experience. You also want to deal with a company that has a good reputation and can give you good references.
  • Price – This is probably a big deciding factor when it comes to deciding which company to use. However, sometimes the least expensive company is not the best company. You need to compare other factors and do your research. Additionally, just because a company is expensive and is giving you the most expensive equipment, does not mean it is the best. You might not need the most expensive equipment, and you certainly do not want the cheapest. You want good quality for a fair price.

What To Look Out For

Do your research and find the company with a good reputation and reasonable prices, like with O.C. McDonald. There are various questions to ask to make yourself an educated consumer. This will make you have a better experience and know who to call if you have any future problems.

What things should you take into consideration for building automation?

When considering an automation system for your buildings heating and cooling system, finding the correct information about your automation process can be difficult. This article will take you through some of the important facts that should be considered before beginning any automation process.

The first item that you should consider before beginning your automation process is the complexity of the project. Finding a balance between necessity and over-engineering will ensure that your project goes smoothly from start to finish. Before beginning a project, you should always get your system engineers to feel comfortable with the design and implementation of your automation system.

Avoiding unnecessary design changes and anticipating any building conditions are essential to keeping a project below budget and ahead of schedule. Another item that you should consider is that building automation systems are changing quickly. Technology that was implemented five to ten years ago is now becoming outdated and may require an upgrade.

Choosing equipment, such as interfaces and software, that will remain relevant in the near future will allow your automation project to be easily upgraded when required. Choosing system hardware and software that will be unsupported within the near future only generates more work and money for your company in the long run.

Choosing Your Controller Interface and Software

If the control interface is the heart of an automation project, then your software is the brain. When choosing these items, one should always consider:

  • System “Openness”
  • Simplicity of Programming
  • Maintenance

Each of these items is important in its own way, but together these items make your choice of hardware and software easier. When choosing a company to supply and support your project, you should always be aware that not all companies produce the same hardware and software. Some companies use proprietary software that requires a specialized technician to provide support.

These technician visits can be costly, and he added cost can eat away at maintenance budgets quickly. The simplicity of your programming is also a key factor in selecting your hardware and software. Being able to easily use the interface, as well as program simple conditions for your system to operate with, can reduce the chance of incorrect programming.

The ability to maintain your own equipment and software is crucial as well. Choosing an overcomplicated control unit can be more trouble than its worth. Ready to get started? Call us today at 408-295-2182

Is a Need for Thermostat Repair Indicative of Other Potential Heating Issues?

A faulty thermostat can be very annoying during the winter and summer seasons. You need your HVAC system properly functioning during these seasons for a comfortable living. A thermostat that needs repair can be indicative of other potential heating issues. Here is how.

1. Debris and Dust

A thermostat that is dirty can lead to sudden system failure and erratic operation. To solve this problem, you need to uncover your thermostat, and gradually clean the internal components, including the switch contact surfaces and the bimetallic coil. First, you need to set the thermostat to its least setting and utilize a compressed air can or soft brush to clean the bimetallic coil. You then need to set the thermostat to the highest setting before cleaning the coil again. Finally, configure the thermostat to the setting you prefer.

2. Mismatched Components

Ensuring your heater operates properly needs proper matching of your thermostat to your furnace system. Thermostats with low voltage are mostly utilized in residential applications. Your thermostat has to be matched to your furnace system depending on the capacity, capability, and type of the heater. Setting up the wrong thermostat type can result in miscommunication and cause system failure. To ensure correct matching, consult HVAC professionals or bring your thermostat when buying updated or new equipment.

3. Poor Wiring

Aging and faulty wiring, disconnections, and loose connections can cause your thermostat to lose the connection to your cooling and heating systems. This leads to an interruption in service. In case your heater quits working properly, it is ideal to check the wiring of your thermostat. If you suspect wonky wiring, make the wiring firm and replace wires as needed, or consult with an HVAC professional.

4. Heat Anticipator Issues

A majority of non-digital, mechanical thermostats have an electrical resistor device at their center. This device is a small metal tab called a heat anticipator. It informs the thermostat when to switch off the furnace burners. When it fails to function properly, it may lead to the cycling on and off of your furnace more often than needed. If your heat anticipator is not properly set, it will need to be adjusted. However, mechanical thermostats have to be manually adjusted, usually using an amp meter in determining the correct setting. At times, you can lightly push the heat anticipator on both sides to solve the issue.

Conclusion

When a thermostat fails you, remember to verify these four issues before deciding to replace it. If you encounter this issue, call us now at 408-295-2182.

How Air Handlers Actually “Handle” Air in Your AC System

What do air handlers do for your air conditioning system? It, quite simply, handles the air. What does this entail? Most air conditioning units, especially in Silicon Valley, are “split” units. This means that they have units both outdoors and indoors. The air handler covers the indoor section of the air conditioning system which is extremely vital.

The role of the handler is to distribute the air through the entire house. The handler unit for indoor air is made of an air coil, blower and filter. The handler brings air in, flows it through the coils (to heat or cool) and then expels it back into the house with the duct system. It is the portion of the AC system that makes sure the air that gets treated flows throughout the entire home.

Air Handler Parts

  • Blower The fan blower will “blow” the rest of the cooled air back throughout the home by using the duct ventilation system.
  • Air filter This filter is placed between the fan and the intake vent to make sure that the air brought into the unit is filtered before it gets cooled.
  • Coils The coils are what truly cool the air inside the house. This occurs when the housed refrigerant within the external unit is drawn out as a high-pressure and high-temperature gas into the internal air handler. A valve then transforms this gas refrigerant into a low-pressure and low-temperature gas that’s brought to the coils. These coils then make the air cooler that’s getting passed over the coils and into the system of ducts. This “used” refrigerant is brought back outside to the external system to start the cycle once again. In the majority of homes in Silicon Valley, the coils can get hotter as well to provide the “heating” portion of a home’s HVAC system.

Would it be helpful for you to use an air handler?

When you use a split-system heat pump or air conditioner, then yes, you would want to use an air handler. The air handler will make sure the air involved in the cooling or heating process is circulating. It’s the indoor component that handles air in conjunction with the outdoor part.

The evaporator coil will bring the heat out from the building to then blow the cooled air through a set of ducts in the building that are connected with the air handler. Call O.C. McDonald’s 24-hour live operator for more information on any questions about your HVAC system and schedule your appointment today at 408-295-2182.

Are there different types of HVAC units?

HVAC manufacturers have engineered several different kinds of HVAC systems that people can choose from depending on their local weather conditions and preferences. There are climates in the U.S. range from the subarctic climate in Alaska to the hot, arid conditions in the desert southwest. There are humid climates in between as well as those that are dry, from warm to cold.

The main kinds of HVAC systems include:

• Air conditioners.
• Heat pumps.
• Gas furnaces.
• Radiant heating systems.

Air Conditioners

All central air conditioners require ductwork to distribute cooled air. They include two copper coils, one that contains the chilled refrigerant and the other that removes the heat from your home that the refrigerant absorbs, called the condensing coil. They use one fan to circulate the air the evaporator coil cools and another to blow off the heat in the condensing coil that the evaporator coil absorbs.

Most air conditioners have two separate components. The indoor air handler contains the blower fan and the evaporator coil. An outdoor condenser contains the condensing coil and the compressor, which alters the refrigerant pressure and circulates it through the system.

Heat Pumps

A heat pump is nothing more than an air conditioning system that contains a reversing valve. The valve switches the flow of heat from summer to winter. During hot weather, the refrigerant absorbs the heat from the evaporator coil and sends it outside to the condensing coil. In the cold months, the process reverses. The condensing coil absorbs the heat from the outdoor air and brings it inside.

Heat pumps work well in just about every climate except Alaska and the northern tier states. They’re the most energy efficient of all HVAC systems since they can extract or supply at least three times more heat or cooling energy than they use.

Furnaces

Forced-air furnaces use natural gas, propane, or oil as fuels. They are the most common kind of heating system in the U.S. Like air conditioners and heat pumps, they blow heated air through the ductwork to warm the home. They’re inexpensive, easy to install, safe and relatively durable.

Radiant Systems

Radiant heating systems are the oldest ways of heating homes. They use a boiler to heat liquids that circulate through tubing placed in walls, floors or ceilings. They provide comfortable, long-lasting heat for homes in cold climates. They’re especially good for people with airborne allergies since they do not blow air.
