Proper care and maintenance are significant in improving the structural integrity of your HVAC vacuum pump and extending their lifespan. However, there will be a time when even the best HVAC vacuum pump will need replacement, no matter how much care and maintenance you give it. Here are reasons to consider for when you should replace your vacuum pump.

Low or Inconsistent Vacuum
The most important indication for the proper function of a HVAC vacuum pump is its ability to reach its specified final pressure, or ultimate vacuum. A vacuum pump with low suction power will be unable to do its job correctly. If your vacuum pump has low suction power, try changing the oil. If after changing the oil, the pump is still unable to reach its ultimate vacuum, then that may be an indicator the vacuum pump needs to be replaced.

Overheating Vacuum Pump
An HVAC vacuum pump should not regularly overheat. If your vacuum pump overheats when operating or constantly shuts down because of overheating, you should consider replacing it. Replacing the vacuum pump will prevent heat-related damage and save you money on costly repairs.

Old Vacuum Pump
While HVAC vacuum pumps can be very durable, they will not last a lifetime if used regularly. An older HVAC vacuum pump is less efficient and more prone to damage. Additionally, there have been many advancements in technology and innovation that apply to HVAC vacuum pumps. Newer vacuum pumps offer even more reliability and speed. They are built to cut back evacuation time allowing you to get your work done more quickly. Depending on the age of your vacuum pump you may want to replace it.

A career path in HVACR is a rewarding experience, especially if you take the time to invest in yourself. Going through a postsecondary education; an apprenticeship to learn the ins and outs of the HVACR industry; or an employment opportunity that teaches you along the way is the first step toward success; but to get the most out of your career as an HVACR professional, you’ll want to take a few extra steps to enable a more fulfilling future.

Don’t Sell Yourself Short. Invest in Quality Tools.

Getting started as an HVACR technician can be an expensive undertaking as you quickly realize the person providing your HVACR tools (more often than not) is YOU. Yes, while there are some companies that provide tools or reimburse you for tool expenses, often you need to budget for your own tools. This is a big reason those starting off tend to lean toward purchasing inexpensive products in hopes of saving money.

The problem is they end up needing to purchase replacement tools more often than those that invest in quality the first time around. While finding the best bargain sounds like a good option when you are just getting started, the idea of tools breaking or not functioning properly may sound a little worse. Plus, you’ll want the bells and whistles soon. While just “the basics” may suffice on day-one of your career; in time, most technicians realize how much faster and more efficiently they can work with tools that do a bit more heavy lifting.

Purchasing durable HVACR tools that hold up to the test of time and withstand frequent drops and the rigors of field use, often means setting aside a slightly higher initial tool investment budget. Luckily student discount programs can help offset these costs.

And just because you’re new to the trade does not mean you need to buy “beginner” tools. It’s best to buy quality tools that provide assurance on the job and serve you well for the long haul versus purchasing more inexpensive, poorer quality tools that cost you more in the long run.

With this in mind, prioritize the tools you know you are going to use often, and whenever possible, purchase them through HVACR tool company program discounts. Consider this an investment in yourself.

Invest in Your Knowledge and Skillset.

Your initial education teaches you the basics of how to install, repair, maintain and troubleshoot systems whether in the commercial, residential or refrigeration space, but you’ll also learn something new on the job every day.

The very best HVACR professionals, or #MastersoftheTrade are always working to understand new technologies, tools and methods for completing a job. That’s why continuing education programs that enhance your HVACR knowledge and skillset— many of which are available free and online and offer NATE credits – can help you stay ahead of the HVACR curve.

If you find yourself with spare time while waiting for measurements or between jobs, take advantage of programs that serve to bolster your knowledge. And of course, always keep in mind the quality of your tools. Never question an investment in you – whether it is a matter of time or money, you and your future are worth it. Every HVACR professional deserves the best – even when they’re just getting started.

Heat pumps are a different animal from furnaces and have some uniquely different parts. If you’re servicing or repairing one that is underperforming, don’t overlook the reversing valve when doing your diagnostic checks.

HVACR Reversing Valve
One of the most critical components in a heat pump is the reversing valve. This valve allows the heat pump to switch from heating the air to cooling the air. It does this by reversing the refrigerant flow in the system. So, instead of removing heat from the air like an air conditioner, it adds heat.

When this valve malfunctions, the system won’t heat or cool efficiently, but symptoms don’t always point to the reversing valve. It’s easy to confuse defective reversing valves with faulty heating and cooling processes. That’s because the symptoms of inefficient heating and cooling are essentially the same.

Stuck Valves
If the system won’t switch from heating to cooling, your problem could be a stuck valve. If the valve is stuck, tapping on the body of the valve with a plastic tool may free it. Don’t bang on it with a hammer as that may bend or break some of the sensitive internal pieces. A plastic tool is all you need. you should also check and clean the capillaries for obstructions. This may free the valve. Look for dents on the valve that may have caused an obstruction inside and check to see if it has scorch marks that could be caused by overheating. If, after examining these components, you still do not free the valve, the system may have an electrical problem.

Electrical Issues
The solenoid in the reversing valve energizes to switch the heat pump from heating to cooling. If the solenoid is defective, it could turn-off mid-operation and not fully open or close. Use your voltmeter to see if the valve is energized and magnetized. If it isn’t, your problem could be a disconnected wire or a faulty solenoid. If everything is working fine electronically but you still aren’t heating or cooling effectively, you could have a leak inside the reversing valve.

Leaking Valves
Before you check to see if you have a leak inside your reversing valve, ensure that your system has the proper refrigerant charge. Overcharged or undercharged systems could cause the reversing valve to malfunction. If your reversing valve has a leak inside, it’s splitting the refrigerant from the hot to the cool side. To check this in the heating mode, compare the temperatures of the suction line from the outside to the suction valve at the bottom. If the difference is more than 3°F, the valve needs to be changed. In cooling mode, check both reversing lines the same way you did for heating mode. A difference higher than 3°F means the valve should be replaced.
