Mini-split or window AC? For NYC apartments, co-ops, condos, and brownstones, the answer is not always simple.

A window unit may be the faster, lower-cost choice for one room. A ductless mini-split may be the better long-term option if you want quieter, more efficient cooling without ductwork.

Our latest guide explains what to consider before deciding, including comfort, cost, building approvals, landmark rules, electrical capacity, and installation quality.

Attention NYC property owners — this one's easy to miss until it's a problem.

If your building has a sprinkler system, a swimming pool, a boiler, or a commercial kitchen, there's a good chance New York State law requires you to have a backflow prevention device installed — and tested every single year.

The NYC DEP enforces these rules, and skipping the annual test can mean fines or even losing water service to your building.

We wrote a straightforward guide explaining who needs one, what installation involves, and why staying on schedule matters more than most people realize. Link in comments.

Thinking about replacing your gas stove with an electric or induction range?

Energo offers gas-to-electric stove conversions in NYC, and that work often fits into a larger gas-to-electric plan for the home. For some homeowners, the stove is the first step. For others, the conversation may also include a water heater conversion, heat pump installation, or electrical panel planning for future upgrades.

Our latest guide explains what’s involved in converting gas-powered systems to electric alternatives, why licensed plumbing and electrical work matter, and how homeowners can phase the process over time.

A standby generator is only helpful if it works when the power goes out.

Our latest guide explains how often a home standby generator should be serviced, what annual maintenance usually includes, and why battery, oil, filter, and inspection schedules matter.

If you own a backup generator this is a helpful read before storm season or summer weather arrives.

NYC building compliance can get complicated fast, especially when heating systems, boilers, gas piping, fuel conversions, and energy laws all overlap.

Our latest guide explains the DOB and DEP violations building owners are most likely to run into including: Local Law 152 gas piping inspections, annual boiler inspection requirements, Local Law 84 benchmarking, Local Law 97 emissions limits, No. 4 oil rules, and permit-related issues.

If you own or manage a building in NYC, this is a helpful place to start before the next deadline or after receiving a violation.

An LL152 inspection is more than a quick look at your building’s gas piping.

For NYC building owners and property managers, the inspection can affect compliance, filing deadlines, repairs, and in some cases, gas service if an unsafe condition is found.

Our latest guide explains what actually gets checked during a Local Law 152 inspection, what happens after the inspection, and the difference between GPS1 and GPS2. Read all about it, link in the comments.

AC issues usually start small: warm air, weak airflow, strange noises, water near the unit, or rooms that never seem to cool evenly.

The problem is that small AC issues can turn into bigger comfort, water, or energy problems fast, especially during a humid NYC summer.

Our new guide breaks down when to call for AC repair, what to expect during a visit, and how to choose the right company for your home.

Paid for a commercial HVAC repair that didn't hold? Most repeat failures in NYC buildings come down to the same root causes — deferred maintenance, refrigerant leaks treated with recharging, systems running past their service window. The repair wasn't the problem. The diagnosis was.

NYC building energy compliance can get confusing fast, especially when LL84, LL87, LL88, and LL97 all overlap.

Local Law 88 focuses on lighting upgrades, tenant submetering, and demonstrating compliance with DOB. If your building has not yet demonstrated compliance, the 2026 filing deadline has already passed, so now is the time to confirm where things stand.

If you own or manage a covered NYC building, our latest guide breaks down what LL88 requires and how it fits into the broader compliance picture.

Big week for a few members of our HVAC team — they just wrapped up a Tekmar training and came back fired up!

Tekmar training is a series of educational programs for HVAC professionals and engineers focused on installing, wiring, and programming Tekmar Control Systems for residential and commercial applications. Their controls are the gold standard for hydronic heating and cooling — covering everything from radiant floor heating and boiler staging to heat pumps, snow-melt systems, zoning, and integrated energy management.

From programming and wiring smart boiler controls to setting up and troubleshooting WiFi thermostats, our guys took full advantage of the opportunity to level up their skills and bring back fresh knowledge for our customers.

The trades are always evolving, and we're committed to staying ahead of the curve. Shoutout to the whole crew for showing up and putting in the work!
