Why Keep Spare HVAC Control Parts?

One of your HVAC controls has reached the end of its life, what do you do next?

You usually have 2 options:

  1. Call a mechanical contractor to come out to the campus, evaluate the situation, order the part, and then install it once it arrives, or
  2. Personally order the appropriate part from the manufacturer or some other source, install it or have a contractor install it.

With either option, there is an inevitable waiting period before the HVAC equipment is back to full operation. During that time, the spaces served by that unit will be unavailable to use without enduring uncomfortable conditions. It’s hard to control when a part will give out, but there are some ways to mitigate the pain caused by these situations. The easiest of these is to keep replacement controls on hand for the most common control parts at the facility. Read on for some of the reasons why this is important.


The Importance of Comfort

As a building operator, one of the highest priorities is the comfort of the building occupants. When a unit is down because of a bad controller, repairing that unit can quickly become a high priority. The Society for Human Resource Management references a study in their blog that shows the effects of temperature on employee productivity. The study, conducted by CareerBuilder, concludes that 22% of people claim that a workplace that is too hot made it difficult to be productive and 11% said the same about being too cold. A broken controller can leave your workplace and its occupants very uncomfortable. But with replacement parts on hand, the amount of time occupants are uncomfortable can be cut down significantly. A contractor can install the part on their first trip to the site, or you can personally install it.


Protect your Investment

Building HVAC systems are usually a large financial investment. Large portions of facility budgets are spent maintaining and protecting this investment. Keeping the systems running as long as possible and in top condition is so important. The Cooling Company blog explains that if a controller is on it’s way out, it will start to show signs that can potentially be very costly. These include the system running continuously, inaccurate temperature readings which leads to discomfort, or a completely unresponsive system. Replacing the controller is the cost-effective solution. But what if that part you need is no longer manufactured or is too expensive for your budget? Often the only option you are given is to make another large investment and upgrade the system. Save your investment by finding discontinued or hard to find parts at an affordable price from a source like Value Controls and keep them on hand to avoid costly repairs.


Time is Money

When you need to get a replacement part quickly, it may end up costing more than anticipated because of expedited shipping costs. To avoid this, shop around periodically for parts that are likely to wear out and when you find a good deal on them buy more than you need at the time. This not only saves you money in the long run; it also gives you peace of mind.

Your controllers and HVAC parts are going to falter at some point and need to be replaced. Having a good supply of replacement parts will help you be better prepared when the time comes.

Programmable Thermostats - are they worth it?

Programmable Thermostats - are they worth it?Programmable thermostats have recently become a hot commodity with homeowners and business owners alike. But are they really worth all the hype?

Let’s look at three reasons why you should definitely invest in a programmable thermostat for your home or business!

Reason #1: Save Money!

The most compelling reason to install a programmable thermostat is the positive effect it has on your wallet. It’s not likely we will see a change in the upward trend of energy prices. A programmable thermostat can reduce your energy usage and lower your monthly energy bill when used properly. So let’s look into how to properly set up and use all capabilities of your new programmable thermostat.

Programmable thermostats allow you to program a schedule that fits your lifestyle. The Honeywell 7-day Programmable Thermostat provides 4 programmable time periods for each day of the week. Set these time periods to correspond with when you will be leaving and returning to the building with appropriate temperatures for occupied and unoccupied times. According to Energy.gov, “turning your thermostat back 7-10 degrees for 8 hours a day” can save you 10% on heating and cooling a year. Even better, the Wi-Fi model lets you do all this from your smartphone, tablet, or computer!    

Reason #2: Improve Comfort

Programmable thermostats provide more accurate space temperature readings which in turn increases the comfort level of the space it is serving. High Quality Heating and Air has been serving the Tallahassee, Florida area for 17 years. In their blog they state that, “Older thermostats are often very inaccurate when setting and reading the indoor temperature. Settings that are off by even a few degrees can degrade comfort and raise utility costs.” (Check out their blog here.)

Once scheduled, the programmable thermostat will maintain that schedule with the corresponding temperatures until you decide to change them. Nobody likes to get off the couch during the game or get out of bed to adjust the temperature. Programmable thermostats eliminate the need to physically walk to the thermostat anytime you want to make a change. Set the programs one time for each season and forget about it. Upgrade to a Wi-Fi programmable thermostat, and make adjustments from your phone whenever you desire.

Reason #3: Protect your HVAC System

Whether you just installed your system or it is getting along in years, keeping it running efficiently will extend its life. Setting a schedule in the programmable thermostat allows the unit to run only when necessary to keep the space comfortable when it is occupied rather than trying to maintain a constant temperature 24/7. This reduces wear and tear on the unit. There is often a misconception that turning the thermostat temperature setting down extremely low will make the space cool down faster. But according to an article by Energy.gov, “Avoid setting your thermostat at a colder setting than normal when you turn on your air conditioner. It will not cool your home any faster and could result in excessive cooling and, therefore, unnecessary expense.”


If you are thinking about upgrading your HVAC equipment because of poor performance, first consider replacing the thermostat with a programmable one. Gaining more precise control of the equipment can help extend its life and allow you to better prepare for purchasing a new unit in the future. The programmable thermostat will transition to your new unit when it is installed and will keep that unit running at optimum efficiency.

Things to Keep in Mind

Buying and installing a programmable thermostat is a a great investment for your wallet and your comfort. As mentioned above, the Honeywell 7-day Programmable Thermostat is a great option for your home and business. Some programmable thermostats such as the NEST Learning Thermostat have the ability to “learn” your habits and adjust the temperature based on detecting occupancy in the space. It offers Wi-Fi connectivity so you can control it from any device. We do, however, recommend turning off the “learning” function and setting your own schedule that fits your lifestyle.  

Finally, installing programmable thermostats is simple; no need to call a contractor. Once you decide which programmable thermostat is right for you, take a picture of the wiring of your current thermostat, remove it from the wall, and install your new thermostat in its place. Keep in mind that the majority of programmable thermostats require a “C” wire to install properly. Take a look at the manual for your new thermostat to see what features it has to offer and how to properly install it.

7 Tips on How to Choose an HVAC Contractor

1. Be wary of an HVAC contractor that gives you a bid or an estimate over the phone.

Just as no two automobiles are the same, no two air conditioning units are the same.  Be wary of any HVAC contractor that tries to give you an estimate or a bid over the phone.  There are far too many factors to take into account that a technician cannot see over the phone:  How is your ducting?  Are there the proper amount of registers per room?  What type of insulation do you have?  What type of windows do you have?…and a dozen other factors…and after all of that, a trained HVAC contractor will then do a Manual-J calculation for your air conditioning system.  None of this can be done over the phone, so again, if someone gives you a bid over the phone, they are either inexperienced, or are trying to gain your business without using the time and gas required for a visit.  When they get there, also be wary of anyone who gives you a bid without properly surveying your house.  A real contractor will crawl in your attic, crawl spaces and walk around the entire house.  If they don’t do this, then they aren’t properly inspecting your house for their Manual J calculation.

2. Be careful of any HVAC contractor that replaces your old air conditioner with the same type of unit as before.

The average air conditioning unit lasts 10-15 years.  Is a 1990 Toyota Tacoma the same as a 2005 Toyota Tacoma?  It is the same with your air conditioner.  A properly trained HVAC contractor will recommend several options to bring your home up to date, and increase the efficiency of your home.

For more information on decreasing energy costs, also see our article:  How to lower your electric bills

If they try and sell you an older model, they are likely trying to unload some of their own inventory.  That is why All Systems Mechanical keeps minimal inventory; we will customize the air conditioning unit for your home, and use the most current, energy efficient units on the market.  If you don’t live near Santa Clarita or Greater Los Angeles, make sure your contractor buys a system new for your house, instead of using older inventory.  It is pretty rare to have the exact system you need for your home just lying an a warehouse, and no not all AC units are the same.  In fact, choosing the proper size is far more important than the make and model.


3. When it comes to how experienced your HVAC contractor is, take it with a grain of salt.

At ASM we have over 25 years of HVAC experience, but we’d also be the first to warn you that experience isn’t everything!  Be wary of someone who is telling you that they have been “doing things this way for twenty years” because the air conditioning business, like all technology, is ever changing.  There are new and exciting technologies that decrease your utility costs and are more efficient at cooling.  Be sure your contractor is well versed in cutting edge technologies, including the most up-to-date HVAC control units – a computer that runs your home or business’s AC system for you, programmable with schedules and preferences.  Experience is important, but it isn’t everything.  In fact, some of our most talented technicians have a computer background and are in their twenties (scary, I know).

4. Your HVAC contractor should be licensed by the Contractors State License Board.

Unfortunately, many HVAC contractors claim to be licensed, but are actually working under the radar.  There is too much at stake, and a licensed HVAC contractor is licensed to manipulate gas lines as well as electrical and plumbing applications – we have to be experts in each to get properly licensed.  You don’t want someone who isn’t closing off your gas line, or properly disposing of refrigerant.  It is a huge problem in California and is tantamount to a doctor operating without a license.

A contractor should have their license number clearly marked on most, if not all, of their literature and on their website.  For instance, All Systems Mechanical HVAC, Ca License No. 963922.  Without a license, there is no insurance that the job will be done properly or that you can take recourse if it isn’t!  Don’t trust anyone who doesn’t have a license.  Period.
