When to Call for HVAC Service: Seven Tips from the Pros

It’s critical that your HVAC system makes sure your home is cozy, controls humidity and boosts indoor air quality. But like any mechanical device, it may exhibit signs of trouble when it’s beginning to fail. Overlooking these signs can cause an emergency breakdown at the worst possible time, necessitating costly repairs. To avoid being taken by surprise, contact a technician from McLoughlin Plumbing Heating & Cooling for consultation if you detect any of these signs your HVAC system needs attention.

Your HVAC System Is Producing Lukewarm Air

If your heating or cooling system fails to generate warm air in the winter or cool air in the summer, there’s a strong possibility it’s struggling. Warm air from an air conditioner could be a sign there is insufficient coolant, a blocked condenser unit or problems with the compressor. Meanwhile, cool air from your furnace could indicate ignition problems, insufficient fuel or a malfunctioning blower motor.

The Furnace or AC Frequently Turns Off and On

Does your heating or air frequently power up and shut down before completing a complete cycle? Referred to as short cycling, this issue strains your system and reduce efficiency. Sometimes, a malfunctioning thermostat will inaccurately measure the room temperature and lead to the HVAC system starting and stopping unnecessarily. A clogged air filter also might be another cause, because this can impede airflow and cause the unit to turn off to prevent damage.

Strange Noises Coming from Your HVAC

An HVAC system generates some noise while it’s working, but any sounds you don’t recognize are usually warning signs. Loud banging might mean parts have become detached, while loud knocking can signal a broken or disconnected component. Buzzing or grinding noises might signify motor issues, especially if parts are wearing out or no longer working properly. Odd noises seldom fix themselves, so a repair is necessary before things deteriorate more.

Your HVAC System Stinks

It’s never pleasant when your HVAC system emits a bad smell, but it might also be dangerous. A damp scent could mean mold is flourishing within the ducts or the unit itself. If you smell smoke, it could point to a serious issue like an overheated motor. And the smell of spoiled eggs is the most concerning because it can point to a gas leak. In this case, turn off your HVAC system, exit the building and get into the fresh air. Once you’re outside and safe, call the fire department for help.

Your Home Heating or Cooling Bills Skyrocket

If your energy expenses shoot up but you haven’t changed your usage habits, your HVAC system could be working overtime to keep your home comfortable. This typically takes place as parts deteriorate and the system can’t operate as efficiently. You can mitigate this issue by maintaining your system regularly with tune-ups.

There’s Excess Humidity in Your Home

An HVAC system that works like it should will control indoor humidity in addition to controlling the temperature. If your home feels unusually humid or you observe condensation on the windows, your system may not be dehumidifying your property properly. Excessive moisture in the air can feel unpleasant, foster mold growth, distort wood furnishings and even negatively affect your electronics. Frequent culprits for high humidity levels include poor airflow, contaminated evaporator coils or an too large HVAC system.

Leaks or Water Around Your HVAC Unit

Discovering water leaks around your HVAC unit is a sign you could have coolant escaping or an obstructed drain line. A refrigerant leak decreases cooling power and might result in ice on the evaporator coil, which creates moisture buildup when the ice thaws. Similarly, a blocked drain line causes water damage if not promptly fixed.

How to Choose Between HVAC Repair or Replacement

If you spot that your HVAC system needs some TLC, but how can you determine if a repair or replacement is best? Here are some points to help you decide what’s best for your home:

• Your HVAC equipment is getting older: Most HVAC systems are good for 10 to 15 years with routine upkeep. If your unit is nearing or has exceeded this age, it may be running on borrowed time. Older systems are less efficient and costlier to repair due to hard-to-find replacement parts, so contemplate upgrading to a modern, energy-efficient model to save on utility bills and pay for fewer future repairs.

• The HVAC system in your home repeatedly fails: If you’re repeatedly calling for heating or air repair, the costs can accumulate rapidly. Eventually, you’ll need to stop throwing good money at it and swap out your finicky system with a new, energy-efficient one.

• Repair costs are accumulating: If HVAC repair costs more than half the price of a new unit, replacement is typically the more prudent investment, especially if the system is several years old.

• Your heating and cooling system can’t keep up: A system that has always struggled to keep your home comfortable may be too small, too large or poorly designed. A carefully selected new HVAC unit delivers better climate control and enhances indoor air quality.
