Home+ Air and Heat vs. T.F. O'Brien: Which Long Island HVAC Company Should You Hire?
T.F. O'Brien is a well-established Long Island HVAC company with decades of local work behind it, and it is a reasonable choice for a straightforward replacement. Home+ Air and Heat is the better fit when you want published pricing, a brand-agnostic equipment recommendation, documented warranty tiers, and rebate handling written into the proposal before you approve anything.
The honest read on both companies
T.F. O'Brien is a good company
They are one of the longest-running HVAC names on Long Island, they hold established manufacturer dealer credentials, and plenty of Nassau County homeowners have had a fine experience with them. If they show up with a documented Manual J, a written scope, and a price you understand, hiring them is a defensible decision.
The limit is usually choice, not competence
A dealer-anchored model tends to steer every home toward the same manufacturer lineup and the same handful of packages. That works when your home is average. It gets expensive when your ducts are undersized, your load is unusual, or a ductless or hybrid design would have been the cheaper correct answer.
Where Home+ is deliberately different
We publish the ranges, we publish the brand reasoning, we size by Manual J, we separate the incentive from the price, and we put the labor term in writing. You can disagree with our recommendation using our own material — that is the point.
We only document what Home+ publishes. For T.F. O'Brien's current brands, pricing, warranty terms, and coverage, verify directly at tfobrien.com . Ask both companies the same questions and compare the written answers.
What Home+ publishes, and what to ask any competitor
Use the right-hand column verbatim on your calls. If a company will not answer these in writing, that is the finding.
| Topic | Home+ Air and Heat | Ask T.F. O'Brien (or anyone else) |
|---|---|---|
| Equipment choice | Brand-agnostic. We lead with Trane, Mitsubishi Electric, and Bosch, and also install and service Rheem, Daikin, Carrier, and Goodman depending on the load, ducts, and budget. | Which brands can you actually install, and what happens if the best fit for my home is not the brand you carry? |
| Published pricing | Planning ranges are on the site before you call: central AC $6,500–$15,000, furnace $3,500–$7,500, ducted heat pump $7,500–$15,000, mini-split $3,500–$8,000 per zone, standard 40-gallon tank water heater $3,700. | Can you show me a written planning range for this type of project before the in-home visit? |
| Sizing method | Manual J load calculation with documented assumptions, plus airflow and duct review. PSEG-LI heat-pump incentives require 100–120% Manual J sizing, so the calculation is part of the file. | Is the equipment sized by Manual J, or matched to whatever is there now? |
| Rebates and incentives | PSEG Long Island Home Comfort is handled as a Participating Partner: a flat $4,000 (market) or $7,500 (income-qualified) on a qualifying heat pump, and $1,000–$1,200 instant on a qualifying heat-pump water heater. Federal 25C ended after 2025, so we do not quote it. | Are you a Participating Partner for the current PSEG-LI program, and is the incentive shown as a separate line? |
| Labor warranty | Tiered labor coverage from 1 to 10 years depending on the Home+ package, alongside 10-year manufacturer parts coverage with registration. | How many years of labor are included in writing, and what voids it? |
| Maintenance plan | Home+ Comfort at $24.99/mo and a Home+ Infinite tier, with the benefits and exclusions listed on the site. | What is included in the plan, what is excluded, and can I read the terms before enrolling? |
| Research material | Brand rankings, model pages, 2026 cost guides, and head-to-head comparisons are published openly so you can pressure-test our recommendation. | Where can I read your reasoning before a salesperson is in my living room? |
| Service area | Nassau County and Western Suffolk, with city-level pages for the towns we cover. | Is my town inside your normal dispatch area, or handled as an exception? |
Prices are planning ranges from the Home+ pricebook, not guaranteed quotes. Incentive amounts follow the current PSEG Long Island program and require written verification.
Align the Scope Before Comparing Price
A lower total can reflect a different system or missing work. Use these categories to compare contractors on the same project.
Equipment and capacity
Sizing and distribution
Electrical, fuel, and condensate
Permits and inspections
Startup and closeout
Warranty and exclusions
Keep it in writing. Include assumptions, exclusions, payment milestones, schedule conditions, and change-order terms.
Verify independently. Check licensing, insurance, credentials, and current reviews with the issuing source.
Choose Home+ when
- You want a written planning range before anyone visits the house.
- You are weighing a heat pump, hybrid, or ductless design against a like-for-like swap.
- You want the PSEG-LI incentive shown as its own line, not folded into a discount.
- You want longer labor coverage available as an explicit option.
- You want to read the brand and cost reasoning yourself first.
Another company may fit better when
- You already have a relationship with a company you trust and the scope is documented.
- You are matching existing equipment and controls that a specific dealer supports.
- Your building or landlord requires a named vendor.
- You want a second proposal to pressure-test ours — we would rather you get one.
Frequently asked questions
Is Home+ Air and Heat or T.F. O'Brien better for a Long Island HVAC replacement?
Both are legitimate choices. T.F. O'Brien is a long-established local company that many homeowners are happy with. Home+ Air and Heat is the stronger fit when you want published planning ranges, a brand-agnostic recommendation across Trane, Mitsubishi Electric, Bosch, and others, Manual J sizing, tiered labor coverage from 1 to 10 years, and the PSEG Long Island incentive documented as a separate line item.
Is T.F. O'Brien a good HVAC company?
Yes. They have decades of Long Island work behind them and established manufacturer credentials. The practical limitation of a dealer-anchored company is equipment choice: if the best answer for your home sits outside their lineup, you may not be shown it. Confirm their current brands, pricing, and warranty terms directly with them.
How do I compare two HVAC contractors fairly?
Normalize the scope before you compare totals. Require exact model numbers with the AHRI reference, the sizing method and assumptions, duct and electrical work, permits and inspections, startup and commissioning, the written labor term, exclusions, and any incentive shown separately. A lower total often means different equipment or missing work.
Does Home+ publish its installed pricing?
Yes, as planning ranges rather than guaranteed quotes. Central AC runs $6,500–$15,000, a same-fuel furnace replacement $3,500–$7,500, a ducted heat pump $7,500–$15,000, and mini-splits $3,500–$8,000 per zone. Final price depends on capacity, equipment match, efficiency tier, duct and electrical work, access, permits, and the labor coverage you select.
Should I get more than one HVAC quote?
Get at least two. Ask both companies for the same documented scope so the comparison is real. If a competitor's proposal is stronger on the details that matter for your home, that is useful information — and if ours is, you will be able to see exactly why.
