As a smart homeowner, you can save by getting design, installation, and fuel delivery right, rather than focusing solely on the lowest price. This guide provides simple checklists, ready-to-use questions, and red flags to help you compare HVAC contractors and propane or heating oil suppliers.

Why Your Choice Matters
You can lock in comfort and costs for years by hiring the right installer. Poor HVAC work can cut performance by up to 30%, which could cause uneven rooms and higher utility bills. Hence, choose contractors who follow ENERGY STAR quality-installation steps and document them.
Fuel safety is just as important. Propane systems must align with NFPA 58 rules for storage, handling, and container placement, whilst heating-oil equipment and tanks are governed by NFPA 31. Before you commit, ask suppliers how they adhere to these codes.
HVAC Contractor Vetting Checklist
Use this quick list to choose a trusted HVAC contractor and fuel supplier:
- Check credentials: Pick NATE-certified technicians you can verify online.
- Look for quality programs: Prefer ACCA Quality Assured contractors who follow ENERGY STAR quality-installation steps. (ENERGY STAR’s ESVI program has ended, but ACCA QA still applies.)
- Require proper design: Every bid should include Manual J (load), Manual S (equipment), and Manual D (ducts).
- Demand clear paperwork: Ask for a room-by-room load report, exact model numbers, planned duct testing, an itemized estimate, and proof of commissioning.
- Watch for red flags: Rule-of-thumb sizing, missing model numbers, or no duct tests.
Steps to Choose a Fuel Supplier (Propane or Heating Oil)
Follow these steps to hire the right fuel supplier:
- Start with quality: For heating oil, request ULSHO or Bioheat blends. They minimize sulfur and other emissions and help keep equipment cleaner. However, if you prefer propane, consider hiring a supplier that adheres to NFPA 58. Also, ensure the supplier gives a clear safety briefing during setup.
- Compare the basics: The delivery should be automatic or will-call. Additionally, support should include emergency services, service area coverage, tank monitoring, and regular maintenance.
- Know the cost: Pricing plans include fixed, capped, pre-buy, or market/variable. You should ask about every fee and any minimums.
- Clarify tank ownership: If you own the tank, you typically have the option to choose who fills it. Leased tanks are typically filled only by the company that owns them.
- Red flags: Avoid contracts with vague terms, hidden fees, no safety briefing, or reluctance to discuss codes and clearances.
Timing and Incentives
You should consider choosing between spring or fall. These shoulder seasons are not usually busy, so it would be easier for you to book work and get fair schedules. Be sure to plan ahead and don’t wait for a heat wave or cold snap, when prices and delays can increase. The following are the incentives you should check before you sign:
- Federal tax credits (25C): The FTC is up to 30% of eligible costs. Also, it is capped at $3,200 per year; this includes up to $2,000 for qualifying heat pumps.
- Utility or local rebates: Use the ENERGY STAR Rebate Finder and your utility’s website to see what’s available.
Safety Corner (Non-Negotiables)
If you smell gas, take the following steps:
- Leave the area immediately
- Don’t use lights, phones, or anything that could spark
- If it’s safe, turn the tank valve clockwise to shut it off
- From a safe spot, call your propane supplier or 911
- Do not go back inside until a professional has declared it safe
Tank Placement Protocols
You must ensure that your propane tanks follow NFPA 58 clearances. Most 125–500-gallon tanks require a minimum of 10 feet from buildings and property lines; larger tanks need more space. Before installation, request a site plan that shows the required distances.
Endnotes
Be sure to vet credentials, demand Manual J/S/D and itemized bids, and compare fuel plans, delivery, and tank terms. Prioritize your safety: NFPA-compliant propane and ULSHO/Bioheat for cleaner systems. Shop in spring or fall and use rebates or tax credits. Aim for steady comfort, lower bills, and fewer surprises ahead.
