How Does an HVAC System Work?

Most modern homes and buildings have efficient heating ventilation and cooling (HVAC) systems that keep people comfortable at various times of the year. It’s probably something you take for granted, but there may come a time when you want to know a little more about how these systems work. The most essential step for understanding an HVAC system is to learn about its anatomy. There are six main parts to the system:

  • Thermostat
  • Furnace
  • Evaporator coil
  • Condensing unit
  • Refrigerant lines
  • Vents

The thermostat is the control panel where you adjust your desired temperature. It measures the air temperature and it can automatically adjust the heating or air conditioning to emit either cool or warm air as needed.

Furnaces produce heat that is blown through the ductwork to heat the building. They can use a variety of different methods to produce heat such as combustion, electric resistance and solar energy.

The Evaporator coil’s purpose is to cool the air. The process of evaporation transfers heat from the air into the liquid compound inside the metal coils, which causes the air around the coils to become cooler.

The condensing unit is filled with a refrigerant in a gas state that is cooled to a liquid state, then pumped into the evaporator coils. This serves to release heat energy that was absorbed by the evaporator coil.

The Refrigerant lines carry a chemical compound in a gas state from the evaporator coil to the condenser coil where the gas is turned back into a liquid and heat is expelled from the system.

The vents are the points where warm or cool air are released into the living or working spaces of the building. They’re rectangular openings with metal slats, and they’re usually located on or near the ceiling.

Three types of HVAC systems

There are many different types of systems to control air temperature, but these are three of the most common types.

  • Split systems
  • Duct-free systems
  • Zoned systems

Split systems have components on the inside and outside of the building. They usually have a furnace, an air conditioner and ductwork to carry air throughout the building.

Duct-free systems circulate air throughout the home or building without duct work by using pipes and fans, and zoned systems allow you to set different temperatures for specific areas or rooms in the building.

If you would like to learn how HVAC systems can provide greater comfort in your building or home, don’t hesitate to call us at 408-295-2182.

How Do You Replace an AC Compressor?

With HVAC units playing an essential role in our lives, it makes total sense trying to understand how they operate and most importantly, being well versed with installing and replacing an AC compressor. An AC Compressor basically serves as an integral component of your air conditioning system by ensuring a consistent flow of refrigerant gas. Over time, your AC Compressor is bound to fail due to wear and tear and experiencing fluctuating air conditioning should be a tell-tale sign that everything isn’t well.

Not only that, but uncharacteristically high sounds coupled with chattering bearings are also a major indicator that your AC compressor needs urgent replacement. Before forking out your hard-earned money, here are a few pointers that you need to get acquainted with.

How to Replace an AC Compressor

Before making any substantial purchase, it’s advisable to confirm whether the compressor still operates at peak levels by evaluating the outgoing temperatures from your air-conditioning system. If its operations are deemed to be deviating from the norm, then it’s high time to replace your compressor.

Identify an Ideal Model

Purchasing an ideal AC Compressor can be a daunting task especially for novice HVAC owners. Before making any purchase, it’s imperative to ascertain that your designated model coincides with your current unit. After all, it doesn’t make sense spending ludicrous finances on the wrong AC compressor. To avoid falling victim to this type of problem, kindly go through the instructions printed on the manual.

Turn Off the Power Supply

As a precautionary measure, it’s paramount to turn off the main electrical supply connection that can result in substantial injury. Whether you’ve hired a seasoned expert or decided to do it by yourself, ensure that the connection to the power supply is terminated during the replacement period.

Remove the Refrigerant with Precision

Having opened the cooling system, you need to exercise utmost caution when removing the refrigerant to avoid spillage. This precautionary principle stems from an environmental compliance protocol that demands the acquisition of outgoing refrigerant into a storage cylinder before the AC compressor can be replaced.

Terminate Refrigerant Lines

Cutting off the refrigerant line is an essential guideline that must be considered before extracting the outdated AC compressor. Since the AC compressor is often located outside, you can still use the manual as a reference to tracing its exact location.

Unscrew the Dilapidated Compressor

Before installing the brand new AC compressor, you must first unbolt the air conditioner’s compressor by removing the housing attached to it. While the AC compressor often comes with a single screw, you must consider adopting this standard setup commonly used for holding both the high and low-pressure lines.

Attach the new Compressor

The brand new compressor must be fixed within the condenser unit with the aid of mounting bolts. Reconnect the refrigerant lines as previously done while ensuring that all other coils have been replaced as well.

Reassemble the Unit

Having completed every task with precision, ensure that your connection to the power source is restored and ascertaining that the air conditioning is operating at peak levels once again.

What are some signs that your home or other building needs heating repairs?

During the colder winter months of the year, it is important to have a heater that isn’t going to break down. There is nothing like running into your home on a cold night to only be met with a temperature that is just as cold as it is outside. It is important to understand the signs that your heater may need repair. This can help you avoid a costly replacement of your entire heater later down the line.

Your heating bill is going up

If you are paying too much for your heating bill, this means that your heater is not working efficiently. You may just need to tune up your heater to lower your utility costs. However, there could be some repairs that need to be taken care of. It is important to consult with a heating professional to determine why your heating bill is so high. This could help you save hundreds or even thousands of dollars in heating bills over the winter months.

Odd noises are coming from your vents

That strange bump that you hear in the night probably isn’t ghosts or intruders. Instead, it could be a sign that your heater is not working properly anymore. It is important to get to the bottom of these clunky, scratchy, or strange noises that are coming from your vents.

It is hard to ever get your home warm enough

If it is hard to get your home warm enough even when you are cranking up your thermostat, you might have some repairs that need to be done on your heater. The thermostat in your home may also need to be upgraded or repaired if you are having this issue.

Your air seems dusty and unclean

Sneezing and coughing is something that just seems to happen during the winter months. However, if this is happening more often in your home, you could have a heater that isn’t filtering particles out of your warm air. If you are noticing that you are coughing and sneezing when you turn the heater on, you should change your heater’s air filter. If this doesn’t solve the problem, it is a good idea to contact a heating professional to see if there are other problems with your heater.

When you notice that your heater might be in need of repair, give 408-295-2182 a call to speak with a heating professional today. They will be able to look at your heater and see if there are any repairs that need to be taken care of.

At its core, building automation serves an innovative management system that allows remote monitoring and optimization of an apartment’s systems with a precise focus on plumbing, lighting and HVAC systems.

Reduced Energy Costs

What Types Of Air Conditioning Will You Need If You Live In San Jose?

San Jose undoubtedly offers a unique living experience characterized by warm temperatures during summer and surprisingly cold temperatures in winter. Whether you are a seasoned or novice homeowner in San Jose, comprehending and thriving in both seasons can pay off in more ways than you can imagine with the aid of an ideal HVAC unit. From enjoying the sunny weather pursuing outdoor activities to braving the cold nights indoors doing productive work, the right HVAC unit can make the ultimate difference in your living experience in San Jose. Before dipping into your wallet and purchasing a specific model, here are a few pointers that you must consider.

Types of Air Conditioners That You Need To Know

Central Air Conditioners

Central air conditioners offer a remarkable option to homeowners in need of experiencing the much-needed coolness in their homes. These models operate by emitting cool air through the duct vents in their home interiors. Unlike other types, central air conditioners are controlled by the main thermostat that regulates the ideal temperature within your home.

Portable Air Conditioners

Portable air conditioners are essentially mobile units that barely need any predetermined installation points. Based on their compact nature, they have become popular models in homes characterized by adequate humidity levels. Portable air conditioners are mainly used as supplements to an existing central air conditioner.

Window Air Conditioners

Window air conditioners are often located by the window and supported by a metal board or piece of wood protruding from the window. With a simple plug to an existing electrical outlet in your house, your window air conditioner is operational from the onset.

Central air conditioners are predominantly the main form of air conditioning in corporate offices while window air conditioners are progressively becoming a household name. Central air conditioners aren’t just confined to corporate offices but also garnered substantial popularity in residential homes as well. With the real estate market booming beyond unprecedented levels, purchasing a home with an ideal air conditioner must be considered with the utmost priority.

If you are in the market for a condominium then you need to pay extra attention to the presence of built-in air conditioners. Most apartments barely install built-in air conditioners which definitely mean that purchasing one will become an urgent task. Before settling on any specific model, it’s imperative to consider a few guidelines crucial in helping you make an informed decision.

Your Home’s Size

Your home’s physical space plays an essential role in the choice of air conditioner purchased. If you are currently living in a modest home, then purchasing the window option would be the best option to optimize on the available space.

Utility Options

Centralized air conditioners provide sufficient heating and cooling services in the entire house regardless of the number of rooms used. This contributes to a negative effect by providing similar temperatures throughout your house regardless of its need. On the other hand, a window air conditioner can be switched off upon exiting the room.

When Do You Need to Replace Your AC Compressor?

Your air conditioner’s compressor is a main component of your outside unit. If it breaks down, it is a major repair that comes with several big considerations. Many people believe that if your compressor breaks down, you need to replace your entire system. However, this is not always the case.

First, let’s go over a few signs that your AC compressor is failing, and then we can determine whether your compressor needs to be replaced or whether you should opt for a completely new system.

These are a few signs that your compressor is on its last legs:

  • Warm Air From Vents – A dying compressor cannot pump refrigerant adequately. If you are experiencing this symptom and no other, make sure your AC technician checks for a refrigerant leak to rule that out.
  • Vibrating Unit Upon Startup – Known as a hard start, this is typically something you see right before a complete compressor failure.
  • Frequently Tripping Breaker – A compressor that is having trouble starting is likely to trip a breaker. However, since there are many reasons your breaker could be tripping, it should really only be regarded as a sign in conjunction with other signs.
  • Rumbling Noise – This might indicate that an important component is loose within the motor.

Also, consider how old your AC unit is. If it is over 12 years old, a compressor failure is not unheard of. It is particularly likely if the unit is over 20 years old or has not had regular maintenance.

Which Should You Replace: Compressor or Entire Unit?

You should look into getting just a compressor replacement if that part is still under warranty. If you have already had multiple parts recently replaced, and your HVAC technician can give the rest of your system a clean bill of health, then a total replacement is probably not necessary. A circumstance that warrants a complete replacement is if the entire system is aging and won’t last very long. Two installations are going to be a bigger cost than having it done all in one go.

There are many other factors as well, so these considerations might be hard to determine by yourself. We’re here to help! Call us at 408-295-2182 to schedule a professional inspection.

What Are Some Reasons You Might Need a Furnace Repair Contractor?

As a business owner specializing in industrial manufacturing and construction processes, it’s imperative to ensure that all your pieces of equipment and appliances operate in optimal conditions. With your equipment operating in prime condition, you can rest assured knowing that productivity is maintained and earning substantial profits is nothing short of the expected norm.

However, most business owners hardly maintain their furnaces in top notch condition despite serving as an essential component in daily business operations. While every furnace is susceptible to exhibiting waning performance signs, you might want to detect such signs much earlier to avoid spending a fortune with replacement down the road. Here are a few reasons you need a furnace repair contractor before dipping into your wallet.

Signs That Your Furnace Needs Urgent Repairs

Consistent Foul Odor

Furnaces are widely known for disseminating certain smells based on the exact type of fuel used. Such odors often subside over time but abnormally pungent odors emanating from your unit are tell-tale signs that your furnace isn’t operating in prime efficacy. These pungent odors can be attributed to undetected gas leaks from the furnace. In such a case, promptly get in touch with an HVAC expert to remedy the problem with precision.

Inadequate Heating

Furnaces are precisely built to provide consistent heating for both residential and commercial purposes. If your furnace isn’t producing enough heat as it should, then it definitely needs repairs regardless of its thermostat readings. Inadequate heating is often attributed to leaking duct tapes and defective thermostats that inaccurately transfer information to the furnace.

Dirty Air Filters

If your furnace exhibits clogged air filters, then operating at optimal levels can be a tall order when trying to circumvent reduced airflow. With clogged air filters, energy consumption and power bills will undoubtedly shoot up beyond the norm. Not only that, clogged air filters have a detrimental effect by introducing foreign particles that can adversely affect the quality of your final product.

Malfunctioning Pilot Light

Every furnace possesses a pilot light that regulates its performance depending on its current light emission. Blue color signifies that your furnace isn’t just healthy but operating as expected. However, yellow or red color is indicative that your furnace is experiencing a ventilation problem that needs urgent repair.

Faulty Carbon Monoxide Detector

With the advent in technology, manufacturers have developed high-quality furnaces by installing a carbon-monoxide detector uniquely designed to inform you of the presence of lethal gases. When the detector constantly rings, you must turn your furnace off and ensure that there is sufficient ventilation in the workplace. Afterward, hire a reliable contractor to ascertain the source of the problem and advise on the way forward.
