Not Cool: 8 Signs Your HVAC Needs Maintenance


A whopping 75% of homes in America have an air conditioning or HVAC system.

And for good reason!

As you know, these helpful household devices regulate the temperature in your property. The push of a button cools you down in the scorching summer months and warms you up again in winter. Throw in the added ventilation they provide and it’s a no-brainer why so many people install one.

However, like any household appliance, the time comes when your HVAC unit starts playing up, and their capacity to heat or cool your home suffers. Even worse, as their efficiency levels dwindle, your energy bills go up.

HVAC maintenance is crucial to preventing such problems, extending the lifespan of your system, and fixing any issues that arise. The tricky bit is knowing when it’s necessary.

1. Ineffective Heating/Cooling

One of the clearest indications of trouble is when your HVAC stops doing its job properly.

It doesn’t matter whether you turn it on and nothing happens, the airflow’s weaker than it should be, or different rooms are at different temperatures. Something’s not quite right and maintenance work will be required. Whether you’ve got dirty filters or a blocked duct, a technician will be able to clear the issue and get the unit up and running again.

2. Opposite Effects

Another obvious sign of trouble is when your HVAC starts releasing hot air when you want it to be cold. Needless to say, this is the last thing you want when it’s the heart of summer and you’re already overheating. You need to cool the house down, not heat it up!

There are actually numerous possible explanations for this particular problem though. The compressor might have malfunctioned, the unit might be running out of refrigerant, or the duct itself could be suffering somehow. In any case, a pro technician like those from Phyxter will help you identify and resolve the issue- whatever’s causing it.

3. Excessive Moisture

The nature of using an AC or HVAC system is that some dampness or condensation is to be expected.

Yet you should always be on the lookout for an excessive build-up of moisture around the unit. This could be the result of a blocked drain or dirty filter. In worst-case scenarios, it could mean that the system’s leaking refrigerant.

In any case, a significant amount of moisture in, on, or around the unit is a cause for concern. Keep an eye on things and nip the issue in the bud as soon as it starts to develop.

4. Unusual Noises

Your HVAC could have been working for years with no issues whatsoever. The result? You know how it’s supposed to sound when it’s in good working order!

By the same token, you should be able to identify when something’s amiss. Keep an ear out for any odd noises it starts to make. Everything from clicking and gurgling noises to banging, clanging, and squealing sounds are clear indications of current (or soon-to-be) issues. Obstructions, belt, and bearing problems, and compressor issues could all be at fault. You can also check Pearson’s Appliance Repair for the same.

5. Funky Smells

Alas, strange sounds aren’t the only things to be wary of. Any nasty odors coming from your HVAC could spell trouble too. Aside from the obvious unpleasantness of a unit that’s blowing bad smells around the house, there could be something far more serious going on inside.

For example, mustiness can mean that mold has developed. As the air pumps out, so too do the dangerous spores that can make people in the house unwell. It goes without saying that burning smells are never good either; they could mean you have an electrical fault.

6. Sky High Energy Bills

As we said in the introduction, inefficient HVACs tend to wreak havoc on your energy bills. Through age or wear, they’re forced to work harder to produce the same effects. They use and waste more energy in the process, which drives up your energy expenditure at the same time.

That’s why it pays (literally) to be vigilant for changes in your bill payments. Something isn’t right if you’re using the HVAC as usual but the bills are going up nonetheless. Get a technician out ASAP to service the system and resolve whatever’s going on. Regular Repairs

7. HVAC Unpredictability

Another sure-fire sign that something isn’t right is when your HVAC develops a mind of its own! It might work for an hour, then turn itself off, only to switch itself back on a little while later. It may turn on, then turn off straight after, or decide for itself what temperature’s right for the home.

As you can imagine, anything of this nature needs to be addressed by a professional technician. With any luck, they’ll have a quick fix to remedy the situation and get your HVAC back under control.

8. Regular Repairs

Does your HVAC need more repairs and replacements than it did in the past? Well, as opposed to routine maintenance work, it might be time to update the entire system (read: buy a new one!).

As frustrating as this can be from a financial standpoint, you can actually save yourself money (not to mention headaches). With fewer repairs to make and newfound energy efficiency, you’ll have more cash in your account each month.

Time to Fix Your HVAC

HVAC systems serve a vital purpose in every house that’s lucky enough to have one. And that, of course, is why it’s so important to keep them well-maintained and fully operational at all times.

We hope the information in this post will help in that regard. Keep these signs in mind and you should be able to tell whenever your HVAC unit needs maintenance work.
