If you rarely think about your HVAC unit, you’re not alone. As long as it kicks on when temperatures drop or rise, you presume it’s doing its job.
While HVAC systems are designed to happily run for years, eventually problems can pop up. Suddenly, you’re either freezing or sweltering regardless of the temperature set on the thermostat. Suddenly you’re frantically searching for HVAC Denver services.
However, wouldn’t it be great if you could catch a potential problem before your HVAC system goes out? Thankfully, most HVAC systems give a few warning signs before they go out. Here are a few common ones to watch for.
Signs Your HVAC Unit May Need Repairs
While HVAC units can suddenly stop working, most give you a warning sign that something’s not right. Catching the potential issue before it becomes an expensive problem can help ensure your HVAC system is ready for whatever Denver’s weather decides to throw at you.
You’re Hearing Loud Noises
Most HVAC systems aren’t completely quiet, so if you hear a little rumbling when the unit first turns on, this is usually normal. HVAC units have a lot of moving parts and they can make a little noise.
However, if your HVAC sounds like an airplane taking off every time you turn on the furnace or air conditioner, it’s probably a good idea to schedule a service call. Some of the other odd noises that can indicate a potential issue include:
- Rattling
- Grinding and clunking
- Buzzing
When your heating, ventilation, and air conditioning systems start making any of these noises it can indicate anything from a broken part like a cooling fan to a loose connection. Even if the HVAC system is keeping a comfortable temperature, it’s a good idea to address these noises.
A loose connection is a relatively simple and inexpensive repair but if you ignore it the problem can interfere with the HVAC’s performance.
Rising Energy Bills
A common sign your HVAC system isn’t functioning properly is when your utility bills start skyrocketing. While Denver winters are freezing and summers can be unbearably hot, this doesn’t mean your utility bills should be high enough for you to consider taking out a second mortgage.
So, how do you know if your utility bills are increasing more than they should? A good way is to compare last season’s average utility costs. Even though weather patterns can change from year to year, they shouldn’t have a drastic impact on your energy costs.
If you’re following energy-efficiency recommendations like keeping the thermostat constantly set at 78 degrees but utility costs are still rising, it may mean your HVAC unit is struggling.
Little to No Air Flow From the Vents
When was the last time you cleaned your air vents? If you can’t remember, it’s probably time to schedule a maintenance call.
Your vents are an essential part of your HVAC system, which is how the unit circulates warm or cool air through the space. If the vents are clogged with dirt and debris, your HVAC system ends up working harder. Not only are you watching your energy costs rise, but it’s also placing unnecessary strain on the unit.
Another reason for little to no airflow can be due to a kink in your ductwork. Yes, your ductwork can develop kinks and it often interferes with airflow. How do kinks happen? There are several causes. A common cause is if you have repair work done around the ducts and they’re not returned to their proper position.
Cleaning your vents comes with an added bonus. You’re moving allergens like dust and pollen from the airflow. If you have allergies or other types of breathing conditions, cleaning your vents regularly can help reduce the severity of your symptoms.
The HVAC Unit Can’t Maintain a Constant Temperature
Are you constantly adjusting the thermostat? Is your HVAC unit struggling to keep the space at the preset temperature? If the answer is yes, it’s time to call a Denver HVAC repair service.
Yes, temperatures can be a little extreme in Denver but this doesn’t mean your HVAC system should struggle. Unless you’re also keeping the windows and doors open, your HVAC system shouldn’t have an issue keeping the space at a comfortable temperature.
If you’re dealing with this issue, the problem may be with your thermostat. The solution can be as simple as replacing worn-out batteries. Your thermostat may also need to be recalibrated and this is usually best left to an HVAC technician.
Unfortunately, the problem can also be with your HVAC unit and this can be harder to diagnose. Repairs are also more expensive when the issue is with the unit and not the thermostat.
You’re Smelling Strange Odors
If you notice a slightly musty smell when you turn your HVAC unit on, it’s not necessarily a reason to start panicking. Musty or dusty smells are common with HVAC systems, especially if it’s been sitting for a few days or weeks. Yes, sometimes the weather in Denver is pleasant enough you don’t need to run your HVAC unit. After a couple of minutes, the smell usually goes away.
However, if you notice a burning smell or the odor of rotten eggs, turn your HVAC unit off and call for an emergency repair. The smell of rotten eggs can mean you have a gas leak. An aroma of burning metal or plastic can indicate an electrical problem.
Keep Your HVAC System Running with Regular Maintenance
Scheduling regular bi-annual maintenance for your HVAC system in spring and fall is an excellent way to prevent costly breakdowns and ensure year-round comfort.
Proactive maintenance by a qualified technician can identify and address minor issues before they snowball into major repairs, saving you money in the long run and keeping your Denver home at a consistent temperature regardless of the season’s drastic weather swings.
