Top 10 HVAC Problems Homeowners Face | Guy's AC & Heating

Many homeowners are unaware of the importance of having their HVAC systems inspected and tuned up on an annual basis. Cutting corners on these services increases the possibility that your HVAC system will experience difficulties operating.

When your HVAC system is nearing the end of its 15- to 25-year lifespan, it is possible that it will experience problems. Is your home experiencing unbalanced heating and cooling, or your HVAC unit is making unusual noises?

Troubleshooting HVAC problems can assist you in determining whether or not you are able to repair the problem on your own. If you are unable to do so, you should call a qualified team of HVAC service technicians to complete the task for you.

Here are the top 10 HVAC issues that homeowners encounter and what you can do to resolve them.

1. AC Running Constantly

The air conditioner often runs within a short duration when temperatures are high, but it should still turn off periodically.

An AC that won’t shut off will only cause your energy bill to skyrocket. This problem may result from a thermostat, compressor, air filters, or electrical parts not functioning correctly.

However, the problem can be solved by turning off the thermostat fan to see whether it will shut off the AC. If it doesn’t, you may need an expert’s help.

2. Ignition Problems

The gas furnace might have ignition problems that can leave you home without heat when you most need it. This problem can be caused by the dirty pilot light and a blocked gas supply.

You need to know what to do when your furnace’s gas is not working. You also need to detect signs of the problem that can help you decide when to call an HVAC system specialist.

3. Dirty Filters

When your filters are dirty, they will restrict the airflow and thus cause your HVAC system to work harder to facilitate airflow in your home.

This unnecessary high energy demand may strain your furnace’s blower, resulting in overheating.

A dirty filter will also cause your ducts to get dirty faster and thus leading to costly HVAC cleaning issues that may necessitate you to replace your HVAC unit.

4. Clogged Drains Pipes or Water Leaks

HVAC units usually produce a condensate as waste after heating or cooling your home. In most homes, drains are commonly used to get rid of the condensate. But if drains get clogged, you may experience leaks or stuffy odors.

Clogged pipes can also be cleaned with a brush, but if you can’t track the leaks, hiring a professional HVAC service is essential.

5. Leaky Duct and Dirty Ductwork

Ducts usually carry warm or cool air throughout your home.

It is easy to overlook ducts as a cause of problems. Your ducks are responsible for carrying heated or cool air around your home. But if your ducts are leaky, they will create various issues that may be expensive or uncomfortable to deal with.

For instance, issues with your duct may mean that your AC and furnace will have to utilize more fuel to keep your home cool and warm. Sealing leaky ducts may be difficult, especially when doing it yourself. But you can seek the help of a professional to seal the leaks.

6. Thermostat Issues

Modern thermostats are programmable, making them more effective in keeping your home comfortable.

However, the problem is to adjust the thermostat setting for your home. You want to be sure you are getting the best from the device. You also understand that thermostat can malfunction, and you may have trouble maintaining correct temperatures for your home.

However, if you have any problem setting your thermostat, you can call your HVAC maintenance service to identify what might be causing the problem.

7. Refrigerant Leaks

The HVAC system depends on a chemical referred to as refrigerants.

Sometimes, this chemical may leak and cause your HVAC system to not operate correctly when the refrigerant level is low. This chemical may cause many problems that may include:

  • Rust in the system’s coils
  • Wobbly fittings
  • Gaps in refrigerant piping

All these issues can cause leaks. The best way to prevent such leaks is to perform regular checks on your HVAC unit. A trained HVAC technician can help you achieve the essential inspections and any cleaning that may be necessary.

8. Dirty Coils

The evaporator coil in your HVAC system is an essential component of your air conditioner.

First, it may only take a tiny amount of dust or dirt to impact your system. slight grime can cause your AC unit’s efficiency to drop by 5 percent.

Your coils can get dirty if your outdoor is located near a busy street where it gets exposed to exhaust; natural debris can also build up on your condenser can cause coil issues.

When an evaporator coil of an exterior unit like a heat pump can be hosed off, a trained technician can clean the coils on an indoor unit such as an air conditioner.

9. Blower Running All Times

A blower can run excessively due to a defective relay.

However, a blower may run continually due to issues with the fan relay, which turns the blower on when heat is needed. If the relay gets stuck, the blower won’t shut off.

10. Tripped Breakers

When your furnace may trip the circuit breaker, it is an indication that the blower is overworking.

If something tries to block airflow in your HVAC system, your blower will be forced to work harder. The increasing demand for energy to cool your home will cause your circuit to trip.
