Factors to Consider When Choosing an HVAC System for Your Home

Tue, 11 Oct 2022 23:43:48 GMT

If your home's indoor temperature is unbearable during the cold and hot months, or you don't like the quality of the air you breathe, you might consider buying a new HVAC system to improve your home's comfort and air quality.

An HVAC system can help you keep your house warm during the cold season and cool it during the hot season. The system also keeps the air clean by filtering pollutants from the air that comes into your house.

However, since HVAC systems vary in size, design, and quality level, ensure that your chosen system can meet your heating, ventilation, and air conditioning needs. Below are some factors to consider when choosing an HVAC system for your home.

Capacity

A good HVAC system should have the capacity to meet your home's heating and cooling needs. Since an HVAC system's size determines its BTU and Ton ratings, ensure that your chosen system is not too big or small for your home. If you choose an incorrectly sized HVAC system, you may experience problems heating and cooling your home, and the system may break down more often due to overworking or short cycling.

Before you choose an HVAC system, seek an expert's help to determine the optimal size for your home. When determining the right HVAC size for you, heating and cooling experts consider factors like the size of your home, level of insulation, and ceiling height.

Efficiency

While HVAC systems help keep homes comfortable, they are one of the appliances that consume the most energy in a home. With energy costs increasing rapidly, you might need a heating and cooling system that uses less electricity to provide your required comfort at an affordable price.

An energy-efficient HVAC system can save you some money in electricity bills and reduce your negative impact on the environment. Newer HVAC systems have better efficiency than older models, but some rate higher on energy efficiency than others. Before you purchase an HVAC system, check its Seasonal Energy Efficiency Ratio (SEER). The higher the SEER rating, the more efficient the HVAC system is.

Climate

Your area's climate can significantly affect your system's efficiency, meaning a system that is efficient in normal temperatures might need to work harder to maintain your optimal temperature in extreme temperatures.

For example, if your home's optimal temperature is 75 degrees, your cooling system will take longer to give you the comfort you need when the ambient temperature is 10 degrees higher than your area's normal temperatures.

Maintenance

Like any other machine, an HVAC system requires periodic maintenance to function optimally. Typical HVAC maintenance includes:

Changing air filters
Changing oil filters for the furnaces and boilers
Cleaning the indoor evaporator
Removing debris from your outdoor unit of the air conditioner

Since professional maintenance costs money, ensure that your HVAC system does not require complex maintenance.

Fuel Source

The air conditioning part of your HVAC system is purely electric, but the heating part can use different fuel types, including propane, natural gas, electricity, and heating oil. Some fuel options may be cheaper, depending on your area of residence.

Also, ensure that your chosen HVAC system is compatible with the fuel sources already installed in your home to avoid the extra cost of buying conversion kits to allow fuel compatibility.

Since an HVAC system is a significant investment, ensure value for money by carefully comparing the available options before buying. The information above can help you choose a system that perfectly meets your home's cooling, heating, and air quality needs. Seek advice from an HVAC expert if you still can't figure out which HVAC system is best for your home.

7 Common Air Conditioner Problems and Possible Solutions

Tue, 11 Oct 2022 23:30:21 GMT

An air conditioning unit is a necessary feature in your home. However, poorly maintained air conditioners can fail to function properly from time to time. This blog post discusses the most common air conditioner problems.

1. AC Blows Hot or Warm Air

An AC that blows lukewarm air will cause discomfort in the house. Your first reaction is to confirm if you have properly set the thermostat. If the thermostat is properly set, move on to the air filter. An overused and worn-out filter may cause lukewarm air to flow from your AC.

Insufficient refrigerant may be another possible cause of lukewarm air. If the refrigerant is low, the large copper line that enters the AC's condenser will not feel cold or moist. Therefore, ask a professional to refill the refrigerant.

2. Air Filter Is Dirty

A dirty air filter will limit airflow and reduce the efficiency of your AC unit. Hence, your unit will have to work harder and take longer to cool the home.

Lack of regular cleaning will make your filter dirty and clogged. Consequently, clean the filter frequently based on the manufacturer's cleaning recommendations. If the filter becomes too dirty, you can replace it with a new one.

3. Window Unit Vibrates

Many air conditioners generate a lot of noise due to the sound of the compressor and fan. However, the presence of vibration sounds is an indication of improper installation. The sounds show that the air conditioner isn't properly attached to your window. Examine the manufacturer's installation guidelines or call an AC expert to reinstall the unit.

4. Electric Control Has Failed

The AC's electric controls may wear out due to frequent use. This problem typically affects oversized AC systems. Furthermore, the terminals and wires can corrode. Corrosion and wearing out can lead to electrical control failure. The solution is to ask a professional to check and fix the electrical controls.

5. Sensor Is Ineffective

The AC unit has a thermostat sensor that is near the control panel. The sensor's work is to measure air temperature as it enters the coils. When the sensor is not in the proper position, the feature won't record the correct temperature readings. The result is an AC that cycles more frequently and functions erratically.

Ensure that your sensor doesn't come into contact with the coil. You can bend the sensor's attached wire to prevent contact.

6. AC Produces a Burning Smell

A burning smell from the AC usually is proof of significant problems. While the smell will appear to come from the vents, the underlying problem may be the air conditioner system.

The smell may emerge when your AC works too hard and overheats. This situation arises if you have clogged filters that reduce the unit's efficiency. Clogged filters force the AC unit to take a long time to spread air inside your room.

Another possible cause of a burning smell may be poor wiring. When you haven't connected the AC's wires correctly, the coatings will singe.

7. AC Won't Turn On

Failure of the AC to turn on is another common problem. The failure may be a result of a tripped circuit breaker. Reset the circuit breaker and try to turn on the unit again.

Another possible cause can be a malfunctioning plug. Check if the plug is loose and plug it correctly.

You can also take a closer look at the AC thermostat batteries. The batteries may no longer be effective, and you need to get new ones. If the AC still fails to turn on, reach out to an AC technician for help.
