HVAC stands for Heating Ventilation and Air Conditioning. HVAC is an acronym used to describe your entire air conditioning and heating system, including the duct work, humidification controls, registers, and air filters.
How do I check the warranty of my HVAC, air conditioner, or furnace?
Generally speaking, if your equipment is less than five years old, there is usually a valid warranty. Warranty information can be found on the label on the outside of the equipment. All warranties are different. Barstow and Sons can easily check your warranty status for you, just give us a call.
Is sound an issue for heating and air conditioning systems?
Yes, different units make various amounts of noise and can have a very distinct effect on sound pollution within your home. Each unit has a different sound rating. Newly manufactured heating and air conditioning systems are quieter than ever, though noise can still be a factor.
What is causing the duct work to pop when my furnace turns on and off?
Popping sounds are usually related to undersized duct design. If the amount of air passing through the duct is greater than the duct size, you will hear popping sounds. Improper duct layout can cause a variety of issues which can be solved by renovating your ducts. Besides excessive noise, other ventilation and air quality problems to look for include:
- Higher energy consumption
- Shorter lifespan of the system
- Uneven heating throughout your home
- Damaged compressor
Why is my HVAC system freezing up?
There are many reasons your HVAC system can freeze up. Beyond keeping your air filter clean and ensuring airflow isn’t restricted, it is vital to work with professionals to figure out the source of the issue. The most common causes of units freezing up include low refrigerant levels, a dirty evaporator coil, or a defective blower motor or relay.
What are zoning systems for air conditioning and heating?
Zoning systems help to parse out your duct work to deliver different temperatures to separate parts of your home. For larger homes with multiple rooms and a variety of usages, different temperatures are sometimes a requirement. Zoning systems can easily regulate temperatures across your home without compromising anyone’s comfort. Zoning systems can be easily installed during new construction of a home, or when you’re replacing or modifying your HVAC system.
Are all HVAC filters the same?
No, HVAC filters come in a variety of sizes and quality. Generally speaking, it is good to use a filter specified for use with your HVAC system as this will optimize performance across your system. Barstow and Sons can provide you with information on disposable and reusable air filters for your HVAC system, just give us a call in Annapolis, MD.
Can indoor air be hazardous to your health?
Indoor air can be hazardous to your health, even more so than outdoor pollutants. Particles found in carpeting, upholstery, and furniture can emit fumes that pollute the air. Cleaning agents, paint, and personal care products can also have chemicals that affect air quality. Proper ventilation in your home and removing harmful airborne particles can help clear up your indoor air. Dust, mold, and other allergens can also contribute to harmful indoor air quality and should be eliminated to reduce potential health concerns.
How do I detect carbon monoxide in my home?
Because carbon monoxide is clear and odorless, the only way to detect it is to have carbon monoxide detectors in several locations around your home. Carbon monoxide is very hazardous to your health and monitoring with detectors is the only way to know if your home has a leak. Never use grills or ovens for heat. Be sure to let your car, lawnmower, or snowmobile warm up outside of your home, and not in your garage with the door closed.
How do I choose the right humidifier?
Like an HVAC system, the right humidifier for your home is based on the size of your home and which rooms need humidifying. There are a wide range of humidifiers at different price points. We can help you choose one that will get the job done and is within your budget.
How often should I change my air filters?
There are several factors that determine when to change your air filters:
- Type of air filter
- Indoor air quality
- Pets in the home
- Number of occupants
- Level of air pollution
Most air filters should be replaced every one to two months. For vacation homes, twice annually is usually suitable.
How can I control my energy costs?
Your utility bills can skyrocket if you don’t have an efficient unit. The best ways to maximize your HVAC system in your home are regular maintenance on your system, having a high efficiency system, and by utilizing zoning and programmable thermostats.
Why is regular maintenance important?
As with a new car or any other major appliance, it is important to have your HVAC system checked and maintained to ensure the unit is functioning correctly. Barstow and Sons offers a variety of maintenance packages to keeping your unit working efficiently.
