HVAC FAQs: Introductory
This category helps beginners get to know about the equipment.
1. What Is an HVAC?
HVAC means heating, ventilation, and air conditioning – a system that regulates and distributes cooled and heated air for your comfort in residential and commercial buildings.
2. How Do HVAC Systems Work?
HVAC works using a forced-air system. It forces hot or cold air through the ducts using a blower. The temperature of the air being forced through depends on whether it is using an air conditioner or a furnace.
Understanding how HVAC works revolves around nine parts: air return, compressor, exhaust outlets, filter, ducts, outdoor unit, electrical elements, coils, and blower.
3. Do HVACs Run on Electricity or Gas?
It uses electricity and gas to deliver cooled or heated air to a building. For cooling your home, it uses electricity, and for heating, it uses gas.
4. What Are the Most Common Types of HVAC Systems?
Four main types of HVACs are on the market, including Split systems, duct-free systems, hybrid systems, and packaged heating and air systems.
5. How Durable Is My HVAC System?
HVACs are long-lasting, up to 25 years. However, you can achieve an even longer duration with proper maintenance handled by a competent technician.
6. What’s the Difference Between HVAC and AC?
HVAC is a machine that delivers heated and cooled air and comprises an AC unit. Most people find it more convenient to say AC. Therefore, the term is used interchangeably.
HVAC FAQs: Purchasing

3. If I replace my outdoor unit, do I need to replace my indoor unit?
The short answer is – yes! It is usually recommended to replace both for several reasons, including the differences in age of the units and unit mismatch leading to reduced efficiency and performance. You can get a warranty covering the entire system with a repair cost advantage when you buy both units.
4. What Size Air Conditioner Do I Need?
It is important to buy the right size of HVAC for your home. Buying the wrong size could end up wasting money. You can only determine the right size by knowing your home’s BTU (British thermal unit). Ideally, it is best to contact your HVAC company or technician for guidance.
5. How do I know if my HVAC unit is under warranty?
The warranty for your unit is often found on the label located on the outer surface of the equipment. Your equipment is likely to be under warranty for less than five years. Ideally, talk to your AC technician for a guide.

Finding the best HVAC contractor is easy with the internet. However, you can ask friends and relations to refer trusted ones. We advise you to do your due diligence before choosing a technician. Conduct your research by reviewing the recommended list to ensure they are good.
HVAC FAQs: Operation
The secret to a long-lasting HVAC is in how you use it. When you know what to do, you can extend the lifespan of your equipment, enjoy greater benefits, and save money.
1. How do I know if my HVAC system is operating safely?
Compare the air blowing out and the air going back in to determine the efficiency of your equipment. For peace of mind, try working with a certified HVAC technician to conduct a specific test to determine your AC’s performance.
He needs to check the indoor humidity, find strange smells, checks thermostat accuracy, and listen to strange noises. Apart from feeling the temperature that you can do yourself, accurate detection for operating safety is what a technician is trained to do.
2. Does adjusting a thermostat up or down really save money on energy bills?
Yes, it can save money on energy bills! The thermostat impacts HVAC energy consumption. A smart thermostat with the ability to turn on and off the AC helps to optimize equipment use and save money.
3. What is a zoning system?
A zoning system segments your air conditioning system to help control the temperature in each segment. If your house has a room with many windows that needs more cooled air than other rooms, a zoning system allows you to control air distribution for efficiency judiciously.
The goal is to have air quality and efficiency in your HVAC.
4. What can I do to improve indoor air quality?
Using a cooling system helps regulate humidity and promote indoor air quality. While eliminating sources of pollution does improve air quality, an efficiently working HVAC can improve the air you breathe.
5. It’s hot out, and my air conditioner won’t turn on. What should I do?
There are several explanations as to why your AC might not turn on even if it is hot out. It could be a problem with the power source – compressor handler switches, thermostat batteries, or circuit breaker. If you are not handy, the best thing to do is to call your AC technician to troubleshoot the problem and fix it.
6. How can I save energy without investing in new systems?
Energy-saving can be achieved by maintaining a proper HVAC operation and maintenance culture. A smart thermostat can keep your equipment running optimally without wasting any resources. It’s wise to talk to a professional HVAC technician to walk you through keeping your system running efficiently.
HVAC FAQs: Maintenance
Everything in life needs proper maintenance, and your HVAC is not an exception. When you maintain your HVAC regularly, you’ll benefit immensely from it.

When you adopt regular maintenance and efficient use of your equipment, you can extend its lifespan. Many homeowners who use professional HVAC specialists keep their units running efficiently for longer periods!
2. How often should I clean or replace air filters in my unit?
Regular cleaning of the filters promotes HVAC efficiency. Experts advise cleaning your filters at least once a year with minimal use. The best thing to do is talk to a professional AC technician to guide you on the best timing for cleaning your filters.
3. How often should I have my unit serviced?
Regular check-ups of your equipment helps mitigate any problem waiting to interrupt the smooth running of your HVAC. It is best to allow a competent HVAC technician to develop a scheduled maintenance plan.
4. What is a SEER rating? Why should I know about it?
SEER means Seasonal Energy Efficiency Ratio. The rating determines HVAC efficiency calculated by the cooling output divided by the total energy used in a typical cooling period. Knowledge of the SEER rating reveals potential energy costs and creates a more friendly energy cost plan.
5. How can I detect AC refrigerant leaks?
Refrigerant leakage is a common AC problem, and early detection saves you money and prevents discomfort. There are several ways to detect Freon leakages, but it is better to call a professional HVAC technician when your AC isn’t cooling as it should.
