F . A . Q

Here you can find out answers for frequently asked questions

HVAC contractors are trained and licensed professionals who know how to size, design, and install heating and cooling systems. They are trained in proper handling techniques, ensuring that your system is installed properly and functions efficiently for years to come. They also keep current on industry regulations and standards. What’s more, local building codes govern the installation of HVAC systems. Often, unlicensed contractors may not be aware of these codes and how they apply to your project.

Licensed contractors meet your needs while remaining compliant with these codes. Also, for an HVAC contractor to maintain their license, they must continue their education by participating in ongoing training provided by their employer or professional trade organization. It ensures that they stay informed on all current industry regulations and standards and know how to apply these to your specific situation.

When you hire someone with professional experience, you know they will do the job right the first time. These contractors have worked on all kinds of systems in all types of homes. It gives them experience and knowledge that you can’t get by simply reading an owner’s manual.

It saves you time and money in the long run because you don’t have to worry about redoing work if it is not done correctly. Additionally, when something goes wrong with your HVAC system, a licensed contractor can diagnose the problem quickly, saving you time and money. In addition, they can advise on future repairs or maintenance that you might need before issues arise.

Licensed contractors have years of experience installing and maintaining multiple types of HVAC systems in all kinds of homes and businesses. They know what types of systems work best in different situations and can recommend an energy-efficient unit that works for your home’s unique layout. Licensed contractors can also access quality parts and equipment from a trusted network of suppliers while the unlicensed ones do not have this option and use non-original parts.

From their experience, they have access to original parts that are not available at hardware stores or online retailers such as Amazon. Additionally, licensed HVAC contractors have all the tools necessary to complete your project correctly. It’s not only more convenient to hire a contractor who already has the tools he needs, but it also means you won’t have to spend money on equipment for just one job.

A licensed contractor must perform work that meets the standards set by the licensing board. In addition to the manufacturer’s warranty on your equipment, the contractor will offer a workmanship warranty on their installation. As a rule, in the case of a warranty claim on equipment, the manufacturer checks who installed the equipment. If the installation was performed by an unlicensed contractor, the warranty may be invalid.
Our company offers a permit obtaining process for the installation of equipment. The process of obtaining a permit includes the preparation of all documents, passing the inspection and HERS test.

If any equipment emits carbon monoxide, even in small doses, it is harmful and dangerous to health and even life. If the equipment starts to emit small levels of carbon monoxide, it will increase carbon monoxide emissions. The main danger of carbon monoxide is that it cannot be felt. You can't rely on home carbon monoxide detectors, as they can't always respond correctly to emissions. Heaters should be checked with professional equipment for carbon monoxide emissions at least once a year before use during the winter season. When equipment emits carbon monoxide, then in this case we do only the replacement of equipment.

1. Price
Price is an important factor. Whether you're purchasing an entire HVAC system or replacing part of your existing system, costs vary based on brand, size, and amount of installation effort. HVAC systems can be complex and typically consist of many components, which can impact cost. For example, central air conditioning systems often cost thousands of dollars, depending on the size. In general, complex systems have higher costs, while simpler systems have lower costs. We can help you choose a system that fits your budget while keeping your home comfortable.

2. Size
HVAC systems come in a variety of sizes, so you need to find the right system for your home. If your home is larger, the smaller systems will have to work harder to keep your home comfortable, reducing their efficiency and lifespan. A properly sized system will provide the heating, cooling, and comfort your home needs. To calculate the appropriate size, you should consider insulation, sunlight, tree cover, ceiling height, and square footage. We can help you choose the right system for your home's size.

3. Efficiency
When you’re looking for an HVAC system, you should consider its efficiency. A more efficient HVAC unit can provide greater comfort while using less energy, lowering your monthly energy bills. Seasonal Energy Efficiency Ratio (SEER) and Annual Fuel Utilization Effectiveness (AFUE) can be used to determine the efficiency of a system. SEER indicates cooling efficiency and AFUE indicates heating efficiency. By combining the two reviews, you can find an efficient system for your home that will help you maximize your savings.

4. Maintenance
HVAC systems need maintenance to ensure they can continue to operate throughout their expected life span. Generally, all HVAC units need annual service to maintain the efficiency and warranty of the system, but some units require more maintenance than others. Our company can help you determine the maintenance requirements for your system so you can ensure it stays efficient throughout its life span.

5. Sound
An HVAC system can be incredibly noisy, depending on what type of system you have and where it’s installed. Noisy units can easily irritate and distract the members of your household, especially if you spend a lot of time at home. Our HVAC professional can design a system that isn’t too noisy and determine where to install noisier components so they won’t disturb you.

6. Repair Availability
When selecting equipment, it is worth considering specialist advice on the ease of repairing the equipment in the future. This may be influenced by the availability of spare parts from suppliers.
