Happy February from T.F. O’Brien!

Welcome to our February e-newsletter. We hope you’re staying safe and warm in spite of our snowy winter weather. Groundhog Day has arrived, and as you know, the original groundhog, Punxsutawney Phil unfortunately saw his shadow. Nassau County’s Malverne Mel saw his shadow as well, but there is hope – Suffolk County’s Holtsville Hal has predicted an early spring. Of course it’s always fun to speculate that the weather will either improve or stay chilly based on these critters’ findings, but it’s best to be prepared for those six more weeks of winter regardless. 

That’s why right now, we’re offering a winter clean and check special, to help ensure your system runs smoothly the rest of the season.

For just $89.50, we’ll make sure your heating system is at the top of its game and prepared to keep you comfortable until the warm weather returns. The services provided include:
  • Clean & Inspect Burners
  • Inspect Pilot Assembly
  • Inspect Flue Piping
  • Replace Customer-Supplied Air Filter (if applicable)
  • Check Carbon Monoxide Levels
  • Test Safety Controls
  • Report on Overall Equipment Condition & Operation
And, if you need us in an emergency, we’ll help you as soon as we possibly can. During inclement weather, we do take our trucks off the road to ensure the safety of our staff, but we strive to get to our emergency calls as soon as the roadways are safe for travel.

This month, check out this information about ductless heating and heat pumps. These heating systems have come a long way and can offer you year-round comfort, because they also provide air conditioning. For instance, VRV systems are ductless and highly energy efficient, providing sustainable energy benefits for years to come. Learn more about them and enjoy an informative video by clicking here. And, everyone wants to save energy. Here’s seven tips that can help you start saving energy today.

Thanks for reading! Hope you have a great February.
 
Enjoy,

Unless Frosty Works for You, You Need Commercial Heating

You know your employees and customers complain when the air conditioning system isn’t keeping your business cool enough in the summer. They’ll also be unhappy when winter’s chill hits and the heating system isn’t up to snuff. Chances are, you don’t have snow people on your payroll. So, you’ll need to make sure your commercial space is adequately heated once the snow starts flying. What are some factors you need to take into account when heating your building?

Your top priority should be effective and efficient HVAC design for your building. You might be thinking, “Wait! I thought the top priority was customer and employee comfort!” Well, a properly designed HVAC system will allow for the right commercial heating in your space – and that will lend itself to that comfort everyone desires. According to the National Institute of Building Sciences, HVAC systems account for 39 percent of the energy used in commercial buildings in the United States. They offer that the use of high-performance HVAC equipment can provide both energy efficiency and cost effectiveness, and when coupled with whole building design considerations, improved comfort and indoor air quality will naturally follow.

It sounds like commercial heating is complicated, but it doesn’t have to be.

Of course, commercial heating and building design can get complex. And if you’re not in the HVAC business, the chances are pretty good you’re going to rely on an expert to help you. At T.F. O’Brien, we never want you to have to worry about heating or cooling your building. We are highly trained HVAC professionals with the credentials you can count on for your commercial heating needs. Our technicians don’t just come into your business and install a boiler; we have engineers on staff that take your whole building into account before recommending the appropriate commercial heating installation for your space.

With the right commercial heating, your employees won’t have to wear parkas in the office – and will be much more productive than they would be shivering around the coffee maker all day. And the more productive your employees, the better it is for your bottom line.

For the best commercial heating services for your business or organization, count on T.F. O’Brien to meet your needs. We’re pleased to service all of Long Island, including Nassau County, Suffolk County and Brooklyn.

Five Reasons You Should Get AC for Your Nassau Home

Summer. Everyone looks forward to its arrival after a long, cold winter (and mucky, rainy spring). Warm days and fun outdoor activities make everyone look forward to the season. Until, of course, the weather starts to heat up to an unbearable point and the humidity starts to set in. Then you and your family probably start to look for ways you can beat the heat in your Nassau home.

Air conditioning is one of the best ways you can stay cool during the summer, but you might not know if you want to make the investment. There are several ways a new AC installation can make a big difference when it comes to your family’s quality of life and comfort.

Here are a few of the main reasons it can help:

You and your family will be more comfortable. Nothing is worse than dealing with a hot, sticky home all summer long. Your home should be a retreat from the outdoor heat, but without air conditioning, it can sometimes feel hotter inside than out. When you install AC in your Nassau home, your family will thank you for it once those temperatures hit the sweltering mark.

You’ll reduce your risk of heat-related illness. For infants and toddlers, the elderly and those suffering with certain illnesses, summer heat can be more than just uncomfortable – it can be deadly. According to the Centers for Disease Control and Prevention, heat stroke and other heat-related illnesses are responsible for hundreds of deaths in the U.S. each year. They also agree that air conditioning, along with proper hydration, can protect people.

Allergy and asthma sufferers may see some relief. The Mayo Clinic advocates the use of air conditioning for allergy and asthma sufferers, largely because of its air cleaning capabilities. They state, “air conditioning reduces the amount of airborne pollen from trees, grasses and weeds that finds its way indoors.” They also point to air conditioning’s ability to help reduce exposure to dust mites, which are a major allergy and asthma trigger for many.

Your home will be less humid. Everyone knows that AC in your home helps you stay cool. Part of the reason it does that is because aside from cooling the air, it also helps to remove excess humidity. And, with reduced humidity comes a reduced change for mold and mildew growth, which can occur if your home is too damp.

You’ll sleep better. The National Sleep Foundation indicates that for most people, the ideal temperature for sleeping is between 60 and 67 degrees Fahrenheit. As you can imagine, that temperature might be difficult to achieve during the summer in the absence of air conditioning. When you have AC in your Nassau home, you and your family will rest easier – making for much more enjoyable days in the sun!

T.F. O’Brien is a full-service air conditioning contractor, serving people all throughout Nassau. When you decide it’s time for AC installation in your home, you can count on us to provide you with professional, quality air conditioner installation, as well as any other air conditioning service you may need. Just give us a call at 516-488-1800 and we’ll help you get the right AC for your Nassau home.

Hiring the Right Heating Service Contractor for Your Nassau County Home

When you need heating services, you want to know that the contractor you’re inviting into your home is qualified to perform the HVAC services you need, whether it’s maintenance, repair or installation. In an article on the Angie’s List website, author Paul F. P. Pogue discusses what you should look for in an HVAC contractor, and the homework you really should do before hiring someone for the heating service needs of your Nassau County home.

Here’s what to look for:

  • Licensure: When you hire a heating service contractor for your Nassau County home, you’ll want to make sure they hold the appropriate licenses. You’re taking your heating system into your own hands if you choose to hire a contractor without the proper licensure. It can mean that your contractor doesn’t have the right education and experience for the job, and there’s a good chance their company isn’t properly bonded or insured.
  • Insurance: It should go without saying – anybody who does any work in your home should be insured. Why? Without the right insurance, you as a homeowner can be held liable in the case of accidental damage or injury. So before you hire someone to perform heating service in your Nassau County home, make sure they’re properly insured.
  • Quality Brands: Does the contractor install brands with a proven track record? If you’ve never heard of what they’re selling, or can’t easily find information on the brand on the Internet, then maybe they don’t. Just like you should be cautious about who is providing heating service in your Nassau County home, you should also be aware of what equipment manufacturers are considered to be the cream of the crop.
  • Testimonials: What do other customers have to say about the contractor you’re considering? Check places like Angie’s List for unbiased customer testimonials. Ask your neighbors and friends if they’ve had experience working with them. Check out the contractor’s website and see if they offer customer reviews anywhere on their website. Word-of-mouth is often a great way to connect with a contractor who will have your best interests at heart.
  • Maintenance Contracts: A great contractor knows that there’s much more to HVAC than installation of new systems. They care about their customers and want to help them keep their equipment running and in good shape for as long as possible. Check to see if the contractor you’re considering offers maintenance contracts along with their other heating services for your Nassau County home. Maintenance contracts provide you with the annual attention your system needs to run its best now and for years to come.

Fortunately, you’ve come to the right place for all of the above. At T.F. O’Brien, we take great pride in providing the residents of Nassau County with the heating service they need in order to stay comfortable all winter long.
