When you need help with your heating, ventilation and air conditioning, you don’t want to hear that your technician is stuck in traffic. You won’t hear that excuse from us. We’re based in Brooklyn, at Sheepshead Bay road - in an office, not a phone drop or a postal address. It gives us quick access to many of our customers. But we also have workstations in Staten Island and Long Island. This way, our techs can quickly help you, whether you have an emergency or a routine call. They can rapidly fan out across Manhattan, Queens, Brooklyn and Long Island, ready to install mini-splits and portable AC units, clean chimneys, service residential and commercial HVAC systems, solve your radiant heat problem or get your furnace running more effectively. Our techs are experienced in all sorts of HVAC installation and repair, from heat pump systems and oil furnaces to air conditioner compressors and ac units. How we began As veterans of the industry for more than 10 years, we formed the company in Brooklyn in June 2016 with just one van and one technician. Fortunately, satisfied customers have rewarded us with many referrals and now we have seven vans and 15 people on our team, including office staff. We’re very proud and very grateful for our success. The team leader is Greg. He oversees all three locations and keeps us organized, making sure we respond to calls and we don’t leave until the customer is satisfied. Our techs are experienced, licensed and insured. We can help you, whether you want a new heat pump, a boiler repair, clean air ducts or a commercial HVAC overhaul.

"I called Premier HVAC Services for a routine check-up, and they never showed up. After waiting 3 hours, they rescheduled for a week later without any apologies. Completely unprofessional and unreliable. I wouldn’t trust them with my HVAC needs."

"We reached out to Brother's as a former customer from 40 years ago. They came to my home, spent over an hour with us to listen to our needs, provide us with samples, and discuss options. Brothers resided our new home, replaced the roof, gutters, soffits, flashing of the chimney, replaced a new window, and pitched part of one of our chimney's. The work was impeccable. The owner was available for questions, the foreman was approachable, the workers kept the property neat, and our home looks brand new on the exterior.

FAQs for home energy audit projects in Holtsville, NY

To prepare for a home energy audit, begin by preparing your space. Clear any obstructions around the attic, basement, ducts, crawl space, appliances, windows, and doors. Gather all your energy bills from the last year and information on home upgrades if you’ve made any changes. If you’ve previously had an audit done, include that information as well.

Finally, be prepared to discuss any questions or concerns you have. If you’ve noticed a rise in your energy bills, hot or cold areas in your home, or unusual sounds from ducts or appliances, make a list to discuss with your auditor.

How often you should get an energy audit depends on the age and condition of your home. New homes with no issues are recommended to get an audit every five years, while older homes should audit every two to three years. If you’ve noticed any changes to your energy bills or other areas of concern, you should get an audit as soon as possible. It’s also a good idea to conduct an audit if you’ve made changes or upgrades to your home, such as installing a new furnace, windows, or doors.

An energy audit takes three to four hours to complete. Your auditor sets up testing equipment, conducts an exhaustive walk‑through inspection, and performs all required evaluations to identify energy loss points. The audit follows a systematic review that includes visual assessments, mechanical tests, and detailed documentation, resulting in a precise report of improvement recommendations.

You can schedule a home energy audit any time of the year—it all depends on what's convenient for you. That said, timing it right can help you tackle issues before they impact your comfort and bills. If you live in a colder climate and want to avoid high heating costs in the winter, getting an audit in the summer allows you to make improvements before the temperature drops. On the contrary, if hot summers are your concern, a spring audit can help you stay cool and save on air conditioning.

To find a qualified home energy auditor, start by searching for local energy auditors with great reviews and recognized certifications like those from the Building Performance Institute (BPI). These credentials ensure they're qualified and can help you qualify for rebates. Don't hesitate to ask about their audit methods and schedule a consultation to see if they're a good fit for your needs. Doing some research upfront helps you get top-notch service and maximize your energy efficiency.

Once you have your energy audit report, it's time to take action. Review the recommendations and prioritize the upgrades that make the most sense for your home and budget. Reach out to experienced pros to get quotes and discuss how they can help. By making these improvements, you'll boost your home's energy efficiency, lower your utility bills, and enjoy a more comfortable living space.
