Summer without air conditioning can be downright miserable in the Fairfax area. If your air conditioner goes out and money is tight, you may be considering buying a used HVAC system to save on the cost of a new one. Today we’re going to answer some common questions about buying used HVAC equipment.

1. What Do You Know About the Equipment?

When you buy a new HVAC system, you generally focus on buying a good brand. You don’t have to worry too much about the individual unit you’re buying. Since it’s new, it’s unlikely to have developed any problems. If you find that there’s a manufacturer’s defect, that’s typically covered by warranty. You can be pretty confident you’re getting a machine that will work well for the foreseeable future.

When you buy used, you don’t have that assurance. You have to learn what you can about the equipment’s history. If you’re buying a barely used system from a reputable dealer, you may be getting a good deal. If you’re buying it from a homeowner, you need to ask yourself why he’s selling it in the first place. Does it even work? Did he maintain it? How often has it needed repairs before now? If you can’t be confident that the equipment is in as good shape as the seller says, you’re taking a huge chance by buying it.

2. Is There Any Kind of Warranty?

New equipment typically comes with a manufacturer’s warranty. The coverage of the warranty varies based on the manufacturer, but major brands typically offer a 10-year limited warranty.

While you can transfer many warranties if you sell your home, you can’t transfer them if you remove your HVAC system from the property where it was originally installed.

3. Are You Buying the Right Equipment For Your Home?

Correct air conditioner sizing is vital for good performance. When your A/C is the wrong size, you either waste energy with a system struggling to keep up, or you end up with moisture build-up from a system cycling off too frequently. If you don’t know how to calculate the correct size of the HVAC system you need, you run the risk of buying equipment that causes more problems than solves.

4. Who Will Install Your Equipment?

Professional HVAC installers are often reluctant to install any system that they can’t guarantee will work. If an installer puts in a used system and it doesn’t work, there’s no way of telling if the fault was with the equipment or the installation.

That leaves you with general contractors — or your neighbor’s cousin — who may or may not know much about air conditioner installation. Since one of the biggest causes of A/C malfunction is improper installation, you’re taking a big risk.

5. What If I Want New Equipment But I’m Not Made of Money?

There’s no doubt new HVAC equipment is a big investment. However, the benefits of having a new system with a full life ahead of it can’t be ignored. New systems tend to be more energy-efficient, so you save money on your energy bills. The security of professional installation and warranties are important factors to balance against the lower cost of used equipment.

5 reasons why HVAC systems visibility needed

Commercial buildings account for more than 35 percent of the total energy consumption. In most of those structures, heating, ventilation and air conditioning systems consume more than 30 percent of the total energy use.

Building owners and facility managers are challenged with getting financial returns from their investments while providing a building that is energy efficient.

As HVAC systems have become complex, non-linear and dynamic, facility managers are increasingly using building management systems to collect data about the performance of the building, as well as energy consumption by individual equipment such as HVAC systems.

Below, SenseWare offers five ways visibility into such data can help drive maximum HVAC efficiency:

1. Comfort of indoor environment 

The importance of an HVAC system in commercial and residential buildings cannot be overemphasized.

The fact remains that fresh air is good for the body, and in commercial buildings, it helps improve productivity. A good ventilation system helps to reduce the number of pollutants, bacteria and odor in a facility.

Data analytics of HVAC systems helps in regulating the temperature of a building and lowering humidity by ensuring that moisture in a building is kept under control. Good ventilation systems remove breeding grounds for dust mites, which contribute to causing eczema.

The American Society of Heating, Refrigeration and Air Conditioning

Engineers (ASHRAE) conducted research that led to Standard 55: Thermal

Environmental Conditions for Human Occupancy. Standard 55 describes how

to assess comfort from specific measurements and predict when most people

will be comfortable.

Data analytics of the HVAC system provides real-time data that helps in maintaining this standard and in preventing any setbacks.

2. Energy efficiency

Operating a HVAC system at optimum efficiency is a challenging endeavor. The number of set points, levels and feedbacks of boilers, chillers, pumps, fans, air delivery components and more can cause costly inefficiencies. Add to that the fact that weather variables affect the heat transfers in a building and increase loads on the HVAC.

Data analytics will provide visibility into your HVAC system with sufficient accuracy that will help you take corrective action and reduce the energy demands and peak load distribution of your HVAC systems.

Facilities Net states that HVAC system maintenance in commercial buildings is responsible for saving more than 40 percent of energy, therefore it is essential to utilize data analytics in understanding the effects of malfunctioning HVAC systems on energy use, energy consumption and energy demand.

3. Improve indoor air quality

According to the Environmental Protection Agency (EPA), poor indoor air quality is among the top factors of environmental risk. Pollutants in the air can aggravate allergies and asthma in some people and cause dizziness and headaches in others.

Air quality depends on various factors like people entering the facility, use of other equipment and presence of electronics. With the proliferation of cheap sensors, air quality data is now being accurately measured.

This visibility into the data can help adjust your HVAC system to improve the air quality. You can develop a maintenance plan that includes:

  • Inspection, serving, and cleaning
  • Replacement of parts
  • Documentation of procedures
  • Calibration of components control system

4. Preventive maintenance

HVAC systems often operate at suboptimal levels at least 40 percent of the time in buildings. This is due to the complexity of the buildings, as well as many moving parts like fans, pumps, air-conditioners, ventilators and dampeners.

Data analytics uncovers the following problems of your HVAC system:

  • Additional runtime
  • Poor control settings and programming errors
  • Stuck dampers causing excess outside air intake
  • Valve leakage leading to uncontrolled supply-air temperatures
  • Outright equipment failure

5. Actionable insights

Data analytics provide essential insights to help with monitoring, controlling and maintaining your HVAC systems. In the absence of this type of information, facility managers physically perform manual audits that are inefficient and time-consuming.

With the advent of IoT, more sensors are being used in buildings for various equipment. The data analytics out of this ocean of data can help determine the best course of action to take to maximize HVAC efficiency.

You can also analyze the information in various ways to better understand the opportunities it presents. For example, you can look at the normalized data for your building type, square footage, schedule and climate.

You can break down the data to better understand energy consumption based on building occupancy and time, thereby identifying peak demand reduction opportunities.

5 Benefits of Good Ventilation5 Benefits of Good Ventilation

Good ventilation may not seem all that important at first glance. When you get down to the heart and soul of it, though, the many benefits good ventilation has to offer, like the five listed below, should make it a priority in your home.

1) Improve Indoor Air Quality
The EPA suggests that indoor air quality in most homes is worse than the quality of the air outside. Unless measures are taken to improve ventilation, like installing a whole house fan, garage exhaust fan and attic fan, you may find yourself struggling with immediate health problems related to poor indoor air quality like irritation of the eyes, nose, and throat, headaches, fatigue, and dizziness, or long-term effects that include cancer, respiratory disease, and even heart disease.

2) Reduce Moisture
Good ventilation helps to draw moist air out of your home, releasing it outside. Moisture is introduced into the air in your home whenever you prepare meals, shower, wash dishes, or do laundry. Without adequate ventilation that moisture has no escape and becomes trapped in your home to generate mold and mildew problems that compromise the structure and beauty of your home in addition to the health of your family.

3) Temperature Control
Believe it or not, ventilation, properly venting stifling air out of your home, can go a long way toward keeping your home comfortable inside when the world heats up outside. Whole house fans, such as the QuietCool QC CL-3100 Whole House Fan, and attic fans, like the QuietCool Smart Attic Gable Fan, are excellent tools to assist with this as they help to remove the hot air from your home allowing cooler air to circulate better within your home.

4) Protect Respiratory Health
Toxins, allergens, bacteria, and moisture in the air in your home can lead to a wealth of unpleasant allergy symptoms, respiratory illnesses, and even asthma attacks. Good ventilation allows these things to escape your home, clearing the air inside so your family can breathe easier.

5) Improves the Smell of Your Home
There’s nothing quite like fresh air to make a room, or a home, smell clean. Good ventilation can help to remove many of the more unpleasant odors in your home, such as mold, mildew, tobacco smoke, cooking odors, and even pet smells.

The five benefits above are a small sample of the good that adequate ventilation can provide for your home. The key for improving indoor air quality and making your home a healthier place for your family and friends is to keep adequate ventilation in your home a priority.
