What You Need to Know about R22 Refrigerant

top view of an air conditioning unitOne of the most common misconceptions homeowners have about air conditioning maintenance is that refilling refrigerant is a normal part of this service. On the contrary, if your system is losing refrigerant, it’s indicative that you need air conditioning repair. Please don’t ever let an amateur HVAC technician tell you that refilling—or, recharging rather—is a normal part of Lawrenceville, GA air conditioning care. The source of the leak must be found, and repaired. Then the refrigerant can be recharged.

But we’re not done there. There’s been a development in the last few years that is important for all homeowners to be aware of. And that’s if you are using an older AC system with R-22 refrigerant in it, it’s about to be fully phased out. This is because of the harmful impact it has on the environment. The good news is, if it’s time for you to replace your air conditioner anyway, you don’t need to look any further than our team for professional installation, and you don’t need to worry about the new system having this outdated fluid in it.

AC Care: Should You Be Concerned about “Dirty Sock Syndrome?”

Girl pinching her nose against a white backgroundTemperatures are still cool enough that you likely haven’t turned on your air conditioner quite yet. But as we’re all very well aware, when spring and summer hit, they hit hard—bringing with them soaring temps and high humidity. As a result, you want a fully effective and efficient whole-home Lawrenceville, GA air conditioning system to keep your household comfortable and healthy.

If you haven’t scheduled air conditioning maintenance yet, that’s okay! Right now is actually the perfect time to do so, before you need to use your cooling system on a daily basis. There’s one issue in particular that we check for during your tune-up and that you should be aware of too, before starting up your AC for the first time. This is water line backups, which can result in mold development and foul smells from your system’s supply vent. This is known as dirty sock syndrome.

Are You Using Your Heater as Efficiently as Possible?

And understandably, you’d like to do everything in your power to save money on your energy bills, including making sure that you’re using your heater as efficiently as you can.

Even if you had your heater maintained before the winter season began, there are still steps you can take to utilize the system more efficiently, while keeping your home comfortable and lowering your heating bills.

Is It Worth It to Sign Up for a Maintenance Plan?

woman's hands writing in scheduleThe short answer to this question is “yes.” But, we don’t expect you to take that at face value. To truly understand the benefits of a comprehensive Lawrenceville, GA AC maintenance plan, you need to understand the advantages of maintenance itself, and when maintenance is best performed.

Generally speaking, we recommend scheduling your maintenance sessions before your HVAC systems’ heaviest periods of use. For your air conditioner, this means in the springtime. For your heater, this means in the fall. But more important than when you schedule this service is how often you schedule it.

For most air conditioner and heaters, once a year—for each system—is sufficient. For a year-round heat pump system, though, you’ll want to schedule a tune-up every 6 months.

However, rushing like this can be, and most likely will be, a mistake.

You might end up with a heating system that is too small for your home, or too big—both of which create efficiency problems. Or, you may be stuck with a heating system that isn’t the best fit for your home for other reasons, leaving you uncomfortable. But how do you know what heating system is best?

Why is my thermostat blank? Grayson, Snellville, Buford

Another Friday! Another Frequently Asked Questions Answered Friday! Today’s question is “Why is my thermostat blank?”

Your thermostat could be blank for a couple of reasons.  The easiest would be that the batteries need to be replaced.  And, yes, even if your thermostat is wired into the unit, it still has batteries.  We did a blog with pictures for general battery replacement a few weeks ago.
