What Are the Signs That Your Furnace Needs Repairs?

How can you prolong the life of your furnace without compromising the quality of their service of having to pay for the power bills through the nose? By ensuring the system is adequately maintained and necessary repairs carried out on time. To achieve this, however, you need to learn how to check on the system and how to identify possible sign that the furnace needs repairs. Note that this doesn’t require special classes, you only need to closely monitor the performance of your system and identify any of these problems:

Inappropriate noise

The almost smooth sound produced by a running heater can be considered appropriate. Inappropriate noise, on the other hand, refers to any strange noise produced by the system during operation. Therefore, should you hear clunking and grinding noises with your system, consider calling in expert repair professionals as this often represents underlying system problems.

System neglect

When is the last time you had your system checked, cleaned, and the air filters repaired? Most furnace manufacturers recommend that you have your system inspected by a professional every three months regardless of its current condition. You should, therefore, consider calling in furnace repair experts if you have neglected it for more than six months.

Poor indoor air quality

Several furnace conditions may contribute to poor indoor air quality. These include dirty or worn out air filters, clogged and dirty ducts or gas leaks from the furnace. Each of these poses health risks to your household thus the need to contact a HVAC repair professional.

Skyrocketing energy bills

How much you spend on heating on a monthly basis can also serve as a great indicator of the current condition of your system. Skyrocketing energy bills are a sign of a stressed system. Stress within a system can, in turn, be attributed to most furnace problems given that its build-up eventually rocks and breaks and down your home’s HVAC system. Calling a repair expert to investigate the disparity in energy consumption, therefore, goes a long way in helping lower the stress and optimize the system performance.

Uneven heat in the house

A properly functioning heater should provide even warmth to all the rooms of the house. Experiencing uneven heat around such as some parts of the house being warmer than the others is, therefore, an indicator of a struggling furnace.

Bottom line

While some of these problems only require soft repairs like cleaning of the air filter, others require extensive part replacement. However, if left unattended, either have the ability to render your system useless, thus the need to contact repair experts as soon as possible. Call us at 408-295-2182.

How Does An Air Handler Work on An AC Unit?

Air handlers are essential to almost all functional HVAC systems. From the stripped back simplicity of cooling a small house, to the large-scale energy transfers required to air-condition commercial real estate – air handlers are everywhere in the world of AC appliances. While the name is self-explanatory, the processes involved are somewhat complex. The main purpose of air handlers is to circulate filtered, conditioned air throughout a building’s ventilation ducts. Each section of the air handler is usually separate from the others, located in a discrete portion of the appliance’s metal body. Though there are varying levels of complexity, air handlers will generally have three essential components.

HVAC Components:

Air Filter: This is usually placed between the intake vent and the coils, making it the first active component. The filtration process ensures that only clean, breathable air is circulated to a building’s occupants. Depending on the level of filtration required, often two or more filters will be placed consecutively.

Coils: These components, which usually take affect directly after filtration, are what heat or cool the air. The air is run over the coils, changing the temperature. The level of heat is manipulated by moving thermal energy between the filtered air and a refrigerant stored in the rest of the HVAC system. This refrigerant is continuously cooled and circulated through the coils, which is what allows the AC to function continuously.

Blower: Once the air has been filtered and the temperature modified, the blower circulates the air through the building. Blowers typically use centrifugal fans powered by electric motors, meaning that their essential function is to change electrical energy into the kinetic energy, which causes the fan blades to rotate. From there, the kinetic energy is transferred from the fan to the air, causing the it to circulate throughout the ventilation ducts.

Given the integral role this technology plays, keeping your air handler functional and effective is absolutely vital to the success of your HVAC air conditioning system. The technology is completely dysfunctional if air is not effectively filtered, conditioned, and circulated. The consequences of poor maintenance range from inefficient waste of energy, to adverse health effects. As such, if there is even a minor problem with your air handler, we can help.

What Should You Look For in an HVAC System for Santa Clara?

Getting a new HVAC system isn’t something that you should take lightly. After all, the heating, ventilation and air conditioning system will ultimately determine the level of comfort experienced in your home. Having moved to Santa Clara, it makes adequate sense to purchase an HVAC system that will not only warm your home during the cold months but also provide a cool environment during the summer season. As such, you might want to consider the following essential factors before forking out your hard earned cash to purchase an ideal HVAC system.

Efficiency

The benefits of purchasing an efficient heating, ventilation and air conditioning system cannot be stressed enough. With groundbreaking advancement in technology, experts have consistently advised homeowners to purchase heating and cooling systems exhibiting high-efficiency rating. This essentially means that the higher the efficiency rating exhibited by an HVAC unit, the lower the energy consumed to heat or cool your home. Efficient HVAC systems are precisely developed to provide warm or cool air to your home with negligible energy consumption.

Durability

It’s undoubtedly clear that HVAC systems fetch thousands of dollars to install and maintain over the years. As much as you may want to buy a heating, ventilation and air conditioning system to last long, it doesn’t make sense to spend a fortune on an HVAC unit that will eventually break down in a few months. Suffice to say, it’s in your best interest to settle for an efficient HVAC system with the unique capacity to function at peak levels when supported by regular maintenance.

Reliability

Exceptional heating and cooling systems should consistently provide prime indoor comfort tailored to meet your current needs at all times. With sufficient maintenance in mind, an excellent HVAC unit must deliver cool or warm air to ensure optimal comfort whether it’s the summer or winter season. An HVAC system that frequently delivers substandard air conditions speaks volumes about its inability to effectively provide consistent and high-quality services.

Refrigerant Used

With the abolishment of R-22 refrigerants in 2015, Federal laws require that each HVAC manufacturer adopts the environmentally friendly R-410A based on its substantial benefits. As a homeowner in need of an efficient HVAC unit, you might want to pay close attention to the product details inferred on the unit’s packaging. Heeding to this crucial piece of advice will go a long way in saving you some extra dollars when replacing your ineffective HVAC unit.

What type of air conditioner repairs can you do yourself?

Have you had your central air unit quit working on you? Have you noticed that it isn’t as cold as it should be? Something may be going on with your appliance that needs some tending to. Air conditioning units are great to have for staying cool on the warm weather days. However, like any other major appliance things can go wrong that will cause it not to work.

You can call in a repair person to diagnose the problem and get it fixed for you. But, if the repair is something minor, you might be able to handle it yourself. Thus, saving you a little money in the long run. Here are a few central air unit problems you could repair on your own, to get your unit working properly again:

  • Poor Air Flow
  • Unit Working Harder Than Normal
  • Blowing out Warm Air Instead of Cold

Air Conditioner Repairs You Can Do Yourself

Change filter- One of the easiest repairs you can do yourself is changing the filter. Filters will get dirty over time. Leaving them that way will cause your air conditioning unit to work harder. Sometimes, it won’t blow cool air at all, because of the dust blocking the filter. Changing it out periodically will keep your unit working efficiently and extend its working life. Check your manual to see which filter you will need and how to replace it.

Clean out condenser coils- Your air conditioning unit, often, will pull in leaves, dirt and other debris. These can stick to the coils, making it work harder. To get your unit working properly again, clean out your condenser coils. Each unit is different, but most can be cleaned out simply with a garden hose. Spray water at the coils to get the debris off, or use a special cleaner that attaches to your garden hose. Be sure to check your owner’s manual to see if there are any special instructions on how to clean it.

Check breaker or thermostat- If you’re experiencing problems with your air conditioning unit, one of the first things you can check is the breaker or the thermostat. It may sound strange, but more times than not, your breaker has tripped or your thermostat isn’t properly set. Check those items first before calling in a repair person. If something trips the breaker, you can un-trip it to get it going again. If the breaker trips again, then you must contact a repair person, because something else is going on that’s electrical in nature. A professional would be the best choice in that scenario.

Repairs to an air conditioning unit don’t always have to be done by a professional. You could do the above minor tips to save yourself a call to a repair person. For major repairs, though, contact a professional to avoid getting yourself hurt or accidentally breaking your coil unit. If you have questions, call us at 408-295-2182.

What Is Included In An HVAC Tuneup?

Are you wondering why your company is spending more money on electricity?

When you first install your heating and AC units, you will notice that your electric costs are fairly low. Modern technology has made our heating and cooling systems much more efficient than in past years. However, heating and cooling units degrade over time. Much like your car, heating and AC units are mechanical and need to be serviced in order to reach their full potential.

This is when an HVAC tune-up is needed.

What Happens During An HVAC Tune-Up?

An HVAC tune-up is an annual inspection and repair of your heating and ac units. A tune-up will keep your systems running at peak efficiency so that they will last longer and cost less money to use.

When the service professional arrives at your business, he will spend anywhere from one to two hours inspecting and performing maintenance on your units.

He will identify what parts of your units are not working at their peak efficiency.

What Happens During An AC Unit Tune-Up?

When tuning up your AC unit, the service professional will:

  • Adjust your thermostat
  • Clean your air filter
  • Repair exposed wires
  • Ensure that your fan is blowing
  • Measure the amperage of the compressor

There are many other smaller tasks that your professional will do such as inspecting your indoor coil and testing your capacitors.

If your AC unit frequently freezes, the inspector will look for blocked airflow, refrigerant leaks, and issues with internal coils. A frozen AC unit can be unpleasant during the warmer months. Frequent tune-ups can prevent the situation from happening.

What Happens During A Heating Unit Tune-Up?

When tuning up your heating unit, the service professional will:

  • Inspect the internal heating elements
  • Check the burners for proper ignition
  • Adjust the flame sensor
  • Test the carbon monoxide detector

During the inspection, the exterior will be analyzed for leaks, corrosion, and proper ventilation. This inspection and tune-up can help your heating unit last for many years and run at peak efficiency.
