Top 8 Signs You Need HVAC Service

Strange Noises, Airflow Issues, and Other Signs You Need Service

When you live in the Midwest, you need your HVAC system to run efficiently pretty much all year. With outdoor temperatures often uncomfortable, windy conditions, and poor outdoor air quality alerts becoming more and more regular — having comfortable conditions in your home is essential.

Although proactive HVAC service can prevent major breakdowns and extend the life of your system, a lot of homeowners don’t recognize the importance of regular maintenance until something does go wrong.

Our expert HVAC service technicians weighed in on some of the top reasons customers call us for HVAC service or repair.

1. Strange Noises Coming From Your System

If you hear any kind of unusual noise coming from your HVAC system, don’t ignore it! Beyond the fact that clicking, banging, hissing, or rattling coming from your closet or basement will grate your nerves, it’s a top signal that something is wrong and you need HVAC service.

Strange noises indicate loose components, electrical issues, or worn-out parts. These are the types of problems that could quickly lead to major issues, including full system replacement.

An HVAC service technician can diagnose whatever is causing the strange noises and repair it before it leads to larger, more expensive problems. Finding a trusted HVAC service and repair provider and signing up for a service agreement can prevent these issues from arising in the first place.

2. Weak or Uneven Airflow

Your HVAC system is designed to evenly push air throughout your entire home. This means each room should reach the temperature you set your thermostat to. If some rooms are warmer or cooler than others, your system could need HVAC maintenance service.

It can be tempting to shut the vents in lesser-used rooms to try and push air into the rooms you’re trying to heat or cool, but blocking those vents could worsen your problem. Instead, call for an HVAC service technician to diagnose the cause. It could be anything from clogged filters or ductwork issues to a failing blower motor.

Timely HVAC service and repair can restore comfort fast.

3. Short Cycling (Frequently Turning On and Off)

Short cycling is often one of the most frustrating HVAC issues for a homeowner to deal with. You get your hopes up thinking it’s running okay, only for it to shut down in a couple of minutes without actually cooling or heating anything the way it should.

This constant on-and-off-again wears down your system as quickly as it wears on your nerves. Short cycling also spikes your energy bills if you don’t call for HVAC service when you notice it happening.

If your HVAC is short-cycling, it could signal thermostat issues, refrigerant problems, or a unit that’s too large or too small for your space. Call a professional HVAC service technician right away to get to the root of the problem.

4. Sudden Increase in Energy Bills

Are you seeing rising power costs in your monthly bill despite steady temperatures outside? That could mean your system is overworking and in need of some HVAC service and repair. Call a trusted technician to give your HVAC a thorough tune-up and diagnose any larger issues that may need attention. They will get your unit running efficiently again, lowering your monthly costs.

Signing up for a HVAC maintenance service agreement can help prevent this from happening by keeping your system running smoothly all year.

5. Inconsistent Temperatures or Thermostat Issues

Thermostat not responding? Room temperature doesn’t match the setting? While thermostat wiring is fairly straightforward in terms of installation, once problems start to arise it’s time to call in a professional.

Thermostat issues may be caused by a fault with the thermostat itself, a sensor failure, a wiring issue, or a larger system issue. Call an HVAC service technician to diagnose the issue and provide you with solutions.

6. Poor Indoor Air Quality (Dust, Odors, Humidity)

If you find yourself spraying air freshener to cover up a musty smell or notice extra dust on your surfaces, chances are you’re dealing with poor indoor air quality. Always check your replaceable filters first, but it can be a good idea to go ahead and call for HVAC service in case the problem goes deeper than the filter.

HVAC service can identify and fix duct leaks, dirty coils, or filter issues. Your indoor air quality is something to take seriously, because it can have a real impact on the health of your family!

7. System Is More Than 10 Years Old

Aging systems are less efficient and more prone to breakdowns, but regular HVAC maintenance service keeps them working longer. Even with the changes to refrigerants the industry faces, technicians have access to what they need to keep these older systems running if they’re in good condition.

If you have an older HVAC system, find a service provider you trust and keep them close! They can help you decide how much life your system has left and can recommend replacements when the time comes.

8. It’s Been Over a Year Since Last Tune-Up

Annual service is a minimum requirement for an efficiently working HVAC system, and the greatest HVAC maintenance service plans include twice-yearly maintenance to ensure everything is in working order for the changing seasons.

Preventative maintenance through regular tune-ups catches issues early and helps avoid emergency repairs.
