When Should You Call An HVAC Expert? Ten Signs You Need One

Most of us take our HVAC systems for granted, enjoying the cool air during Utah’s hot summer months and reveling in the warmth during the cold of winter. When things go wrong, it’s not always easy to tell if it’s time to call in the experts or to DIY a fix yourself.

Here’s are the signs to be on the lookout for and call an air conditioner professional at All Hours Plumbing, Heating & Air if they occur.

10 Signs That You Call and HVAC Expert

1 – Noisy System

A dead give away that your system is about to bite the dust is noise. Those clangs and bangs when the motor turns on and off are not a good sign. Your system should quietly transition and barely be noticeable.

When this happens, it’s important to get a HVAC expert out right away. They may be able to save your system with an inexpensive fix, such as tightening a component, before the whole thing shuts down.

2 – Temperature 

If you notice that your thermostat is set to cool but you’re sweating, or you’ve got a sweater on and the temperature is turned all the way up—you’ve got a problem. Check by holding your hand under a vent and feel the temperature of the air that is blowing. If it’s not running cold or hot, give us a call.

It could be a serious issue, or you may just need to clear out some clogs, charge your refrigerant levels, or clean the coils. There could also be a leak in the refrigerant line. This is one reason an annual service is beneficial, because it eliminates or identifies many of these problems before they occur.

3 – Smells

There’s a musty odor coming from your vents. Or, more important, there’s the smell of an electrical burn. Musty smells may indicate mold developing somewhere. And that can lead to serious health problems. 

A burning smell is even more serious. This indicates an electrical issue that could lead to a house fire. Call us immediately if this is something you notice.

4 – No Air

Worse than air that isn’t blowing hot or cold is air that isn’t blowing at all. You could have a blown compressor or circuit. We can diagnose the reason and check your ducts for blockages. 

Before you call us, though, double-check your filter to make sure it’s clean. Also, make sure that at least half your vents are open. Sometimes, this can be an easy DIY fix.

5 – Rapid Cycling

You start to notice the air conditioner or furnace turning off and on frequently. Or, your outdoor AC unit never turns off and runs constantly. Now, if the weather is extremely cold or hot that day, it’s natural for your unit to cycle more frequently than on normal days. But, if your unit is doing a rapid cycle for no reason, that’s a good reason to call us.

When this starts to happen, your unit is probably aging and it’s time to start planning to replace your system. Your HVAC technician can tune up your system and provide regular maintenance which will extend the life of your unit. Consult with us to determine if it’s time to update your HVAC.

6 – Your Bill Increases

Maybe you haven’t noticed an issue with smells, sounds, temperature, or air flow but all of a sudden, your bill is through the roof. This may indicate that your system is running inefficiently. Your energy system is trying to compensate in order to heat or cool your home.

Each day your system operates inefficiently, is another day you lose more money. We can save you in the long-term if you call us sooner rather than later.

7 – Your System Is 15-20 Years Old

At this age, your system is going to start to decline in performance. While it may still work, you might be paying more for your energy costs, or you might not be getting the right temperature for your home. 

If you have had regular maintenance from an All Hours Plumbing, Heating & Air HVAC technician, your system will last longer and you can defer buying a new system until you notice a serious problem. If your system has been poorly maintained or irregularly serviced, you’ll likely need to replace your system.

8 – Your System Doesn’t Fit Your House

Sometimes builders may place a standard unit in a home, but don’t properly measure the square footage of your home or take into account important variables that affect the temperature, such as window sizes and placement. This can make it difficult for you to effectively heat or cool your home without blowing a lot of money on your utility bills.

Our technicians can help you evaluate your home’s unique needs and determine if your unit is the right size or not. 

9 – Water Leaks

If you notice puddling water around your unit or even freezing, that could be a sign that you have a block in your condensation line. Blocked condensation lines leave moisture on your condensation coils.

And the fluid may not be water. You may have a freon leak which can be a very expensive problem if it’s allowed to get any bigger. 

10 – Indoor Humidity

Unless you have a humidifier that is intentionally increasing the humidity in your home, you shouldn’t feel much humidity at all if your air conditioner is running. This is because they are designed to remove moisture from your home.

So, if you are feeling any humid air while indoors, your unit probably needs to be recalibrated or you may need to have a whole-house dehumidifier installed. If you have high humidity levels, that can contribute to the growth of mold.

Other Times You Should Call An HVAC Expert

Don’t wait for problems to develop before calling an HVAC expert. You should have regular annual maintenance for your furnace and AC unit to keep issues from developing into serious problems that require expensive repairs or whole system replacements. 

Another time you should call us is if you are buying a new home or if you are remodeling and adding square footage to your home. We can evaluate your system to make sure it’s the right fit.

And finally, it’s always a good idea to have us check your system before the warranties for your systems run out. If there is an issue that needs to be taken care of, it will be less expensive for you if it’s done under warranty.
