Does Heating and Cooling Duct Work Take a Long Time to Install?

Ductwork is an important part of your heating and air conditioning set up. Ductwork is used for distributing air throughout your home once it has gone through the heater or air conditioner. It also sucks air back through the ducts to create equilibrium in the home. Your ductwork has a direct impact on air quality. Whether you run a warehouse or a small office, air conditioning and heating is a necessity.

Over time, ductwork can need replacing. It may need to be replaced because of a bad design that is hampering air flow, or because it is simply older. Bad ductwork can have an effect on employee productivity due to reduced air quality and/or bad air circulation. When choosing to get your ductwork replaced, time is an issue. You want your office, warehouse, store, or other business to be back up and running as quickly as possible.

What factors affect how long ductwork replacement takes?

It is hard to give a definitive timeframe for all ductwork since there are many factors that affect how long it will take to replace ductwork.

These include:

  •  Building Size
  • Number of Air Conditioning Units
  • How much redesigning is necessary for better air flow.
  • Accessibility of ductwork.
  • If the construction is new or already existing.
  • Type of ductwork.

While each item on this list plays a factor in the length of time for ductwork replacement, normally ductwork replacement takes at least a day or two for normally sized buildings. Larger buildings may take three to four days, depending on the size of course. If you have a large building with more than one air conditioning unit, that will also have an effect on the installation time.

The other major factor in time mentioned above is if ductwork is being installed in new construction or an already existing building. Ductwork installed in new construction can be done quickly because there are fewer obstacles to accessibility. New construction also offers the benefit of being able to work a new design, versus having to work within an old design and possibly find ways to improve it.

Also, ductwork types affect installation time. Industrial style sheet metal ductwork will take longer than the fiberboard styled duct working. If you are building new construction, or need your ductwork replaced in your current building, we can help you! Call us at 408-295-2182 today.

How Often Should You Really Be Changing Your Air Filters?

One thing that many homeowners may not know is how often they should be changing the air filters on their HVAC unit. The air filters are important because they remove particles, allergens, and other pollutants from the air, improving the indoor air quality of your home. Additionally, changing the filters can increase the life of your unit.

Since the filters play such an important part in keeping the air in your home clean, it is important to replace them as needed. Changing your filter is easy to do and doesn’t take much time at all. The hardest part is figuring how just how often you should really change your air filters.

How Often Should You Change Your Air Filters?

Essentially, you should base the timeframe for changing your filters on how often the system is used. If you have a vacation home, it may be okay to change the filters less often than in your everyday-living home. This is because you will use your system more often in the home that you live in every day. The actual timeframe varies, however, based on a few different factors.

Factors That Affect When You Should Change Your Air Filters

  • People and pets in the home

The more people and pets, the more particles are getting into the air. More dirt and debris are being carried into the home on each person, and having pets just adds to that. With pets come dander, dust, pollen, and dirt. If you have even one pet, you should change your filters at least every 2 months. If you have more than one pet, you should actually change the filters each month. For a single person home with no pets, the filters could be changed as little as every 4-6 months. If more than one person lives in the home, but there are not pets, the filters could be changed every 3 months.

  • The type of filter you use

If you use a high-quality filter, you will get more life out of it. The high-quality filters work to filter out even more particles and debris than less effective ones, lengthening the life of the filter.

  • If you follow the replacement recommendations

Each manufacturer will suggest how to properly replace a filter. If you follow those suggestions, you will likely get more life out of them than if you replaced them incorrectly.

  • Allergies

If someone in your home has allergies, changing the filters more often can be beneficial to their health. When this is the case, your air filters should actually be changed every month. If you need help changing your air filters, or if you have any questions, call us at 408-295-2182. We can help make the process easy on you.

How Much Can You Expect an Air Conditioner Compressor to Cost?

The home ac compressor unit is one of the integral parts of the central air conditioning system. Installing your compressor is a significant project. The cost of the compressor will also depend on whether you want to install a new one or if you want a replacement. Replacement costs will also consider whether your old compressor is still under warranty or if it is over eight years old.

The comparison between the cost of replacing a complete ac and coil or the evaporator coil helps to determine whether it will make more sense to replace other than repairing the ac compressor. An additional cost to consider is the labor cost that you will incur for installation. Therefore, below is a review of the amount you can expect to pay for an air conditioner compressor.

AC Compressor Cost Factors

The cost of replacing a compressor for your home AC system is dependent on certain factors. These factors include:

  • The availability of a warranty for the compressor parts
  • The size of the AC compressor
  • The type of compressor and,
  • The consumer brand ratings

Usually, the warranty covers the cost of the parts. Replacing an Air Conditioner Compressor that is still under warranty will incur an average cost of around 645 dollars. If the air Conditioner Compressor is not under warranty, buying a new one will cost you an approximated amount of 1280 dollars inclusive of the installation cost.

Additional supplies are also needed. In most cases, the supplies are never warranted even though the air conditioning compressor might be warranted. Below is a list of the supplies and their cost:

  • Cost of Installation Supplies
  • Copper fittings and connectors with the cost between 35 to 100 dollars
  • Line filter or dryer with the cost between 35 to 75 dollars
  • Contractor, capacitor and hard start kit with the price between 35 to 150 dollars
  • Misc silver solder, electrical connectors with the price between 15 to 25 dollars
  • Refrigerant recharge with the price between 150 to 300 dollars

AC Compressor Installation Cost

You will also incur labor cost or a diagnostic fee unless the compressor is under warranty. A diagnostic fee ranges between 59 and 129 dollars. The typical cost for a service technician ranges between 60 to 90 dollars per hour, and the service helper is paid 60 to 75 dollars per hour.

What Is an HVAC Air Handler, and Why Is It Important?

An essential part of any heating, ventilating, and air-conditioning (HVAC) system is the air handler. This unit acts as a large fan that blows the cooled or heated air through the ductwork, to be delivered into each room of your building. Without this mechanical device, the cool or warm air will only just trickle out of your vents.

Additionally, the air handler regulates the amount of air necessary to achieve your desired temperature, as well as filtering the air to keep it fresh and clean. Think of the air handler as the heart of your HVAC system. There can be several varying elements that make up an air handler, depending on the needs of the building it supports. Air filtration is found in most units as it serves a vital role in keeping the air dust free and the ductwork clean.

Some air handlers may contain additional heating and cooling components to help keep a fluctuating air supply steady. Other elements that can be utilized are humidifiers to negate dry air and static electricity, mixing chambers for the introduction of outside air, and a heat recovery device for added energy savings and capacity.

Why do you need a great air handler?

Since the air handler is in charge of regulating how much cool or warm air needs to go where it is critical that your unit performs at the same capacity as the rest of your HVAC system. Sometimes the air handler might wear down over time and perform with reduced efficiency.

This is bad news not only for your heating and air conditioning bill but for all other parts of your HVAC system as well. On the other hand, if you have a new HVAC system installed, but leave in an old air handler, your new installation will suffer increased wear and tear.

If your air handler is not operating at the maximum performance you are losing out on:

  • Energy efficiency
  • Higher quality air
  • Reduced strain on other HVAC components such as the heat pump

For these reasons, it is critical that your air handler is properly serviced and kept up to date. Furthermore, by installing a new air handler yourself, the chances of imbalanced performance between all components of your HVAC system will foot you higher maintenance bills down the road.

What Do You Need to Worry About Most with Industrial Heating and Cooling?

Your industrial heating and cooling system is, in many ways, the silent backbone of your company. It is the central component to keeping the environment of your company and its employees and customers comfortable and safe.

In a comfortable environment, performance rates soar allowing your company to reach its full potential. In a nutshell, maintaining your heating and cooling system is a vital factor in the growth of your business. To ensure your HVAC system is working at the optimal performance you must be aware of the top worries with industrial heating and cooling.

Top Industrial HVAC Concerns

  • Dirty or clogged filters

Dirty, clogged, or worn filters will cause your heating and cooling system to work harder thus creating higher energy costs and a shorter lifespan of your HVAC unit.

  • Leaking refrigerant

Refrigerants are used in your HVAC unit to cool and dehumidify the air. Without a proper level of refrigerant, your building will become too warm, your systems condenser will work overtime, and ultimately you will face much more expensive system failure.

  • Thermostat malfunctions

The thermostat controls your HVAC systems regulation of timing and hot/cold air production.

  • Improper air balance

Dampers help to control the heated or cooled air that flows through your business by systematically reducing or increasing the airflow to a specified area of ducting. Without regular and routine maintenance a minor HVAC problem can quickly turn into a major expense that will dip into your expense budget.

Before allowing preventative maintenance items to eat away at your company’s expense budget, incorporate a plan to monitor your industrial heating and cooling unit. Ensure that the items listed above are checked routinely. Replace thermostat batteries and filters no less than quarterly. Proper care of your heating and cooling systems will not only keep your energy costs in check, but it will also improve the overall air quality within your establishment.

Regularly servicing your heating and cooling system prevents many issues that may keep your unit from operating properly. The best thing you can do for your industrial heating and cooling system is to invest in a preventative maintenance program.

When Is It Time for an Air Conditioner Compressor Replacement?

At some point, your air conditioning unit will need to be replaced. With age comes the need for increased repairs, efficiency issues, and other problems. It is important to make sure that you know when it is time for an air conditioner compressor replacement.

There are several things that you should consider when thinking about replacing your air conditioning.

  • Age. Consider the age of your unit. If your unit is just a few years old, you may be better off just to have it repaired. If you have a much older model, it will be more difficult to find the parts needed, and the general well being of the machine may be compromised. If your unit is over 15 years old, you may automatically want to consider replacement.
  • Energy efficiency. Running your HVAC unit will make your power go up as they use a lot of power. However, there are many newer models out on the market today that is very energy efficient. If your unit is 10 years or older, you may want to consider switching to a newer model as they are more energy efficient, and can help to lower your energy costs.
  • R-22. If your unit uses R-22 refrigerant which is also known as Freon, you will need to consider getting a replacement unit. The EPA is phasing out R-22, and that has made it very expensive to get. A pound of Freon can cost anywhere from $40-$175 depending on the location. For people who have a leak, the repair could quickly get up to $1,000. The newer refrigerant is environmentally friendly, and will completely replace R-22. Consider switching to an R-410A refrigerant.

Other Factors That May Factor in When You Consider Replacement

There are also some other factors that you may want to consider when deciding whether it is time to replace your compressor. Take into consideration how many times you make repairs on the unit.

If you are constantly making repairs, it is time for an upgrade. You will also want to consider your energy bills, and whether or not your house is too hot during those hot summer months. If you need help in deciding whether or not your unit needs to be replaced, call a professional HVAC company that can help you to determine whether or not you should get a new unit. We can help you immediately. Call us now at (408) 295-2182.
