What 7 questions should the SO HVAC decision checklist answer?

What this 7-point checklist is for

If you live in Ontario and you have a quote, a recommendation, or a system that is acting up, this checklist gives seven clear checks to run before you commit to a repair, replacement, or upgrade. Use it to compare competing quotes fairly, gather the documents and measurements that matter, and prepare for an independent, no-pressure second opinion from SO HVAC. The checks combine industry best practice and pre-retrofit assessment principles used in building retrofit guidance.

The seven checks to run before you spend thousands

Treat each numbered item below as a practical, evidence-backed check you can do yourself or ask a contractor to document. After the seven checks you will find a short scoring method to compare bids, a micro-list of what to bring to a second-opinion visit, and local service notes for Ontario homeowners.

1) What is the system age and maintenance history?

The manufacture and installation dates, plus routine maintenance records, are the first facts that narrow repair-versus-replace choices. Older equipment is not automatically due for replacement, but systems beyond typical service lifespans or with spotty maintenance may fail more often. Photograph nameplates or serial numbers and collect service invoices or filter replacement dates so any assessor can confirm age and history quickly. If a contractor cannot or will not provide clear maintenance notes, ask why before agreeing to work. Having dates and receipts reduces guesswork when comparing multiple quotes.
2) Is the equipment performing to spec and what diagnostics show?

Reliable diagnostics separate a minor repair from systemic failure. Useful, measurable checks include temperature split across the coil, static pressure in duct systems, ignition and burner behaviour on gas furnaces, refrigerant charge for air conditioners and heat pumps, visible corrosion or leaks, and any error codes from control modules. Record measured values and error codes in writing or photograph diagnostic screens so contractors supply consistent explanations. Pre-retrofit assessment guidance recommends these measurements to decide whether components are serviceable or whether replacement is the prudent option.
3) Is the system correctly sized and are the ducts in good condition?

Right-sizing affects comfort, humidity control, and operating cost. Ask whether a quoted replacement uses a Manual J heat-load calculation or similar sizing rationale and request it with the proposal. Oversized equipment can short-cycle and fail to dehumidify; undersized equipment struggles to meet the temperature on extreme days. Inspect ductwork for large gaps, missing insulation, crushed runs, or poorly located returns. Document visible duct leaks, lack of insulation on attic runs, and any non-standard routing so every quote includes the same ductwork assumptions.
4) What are the likely operating costs and fuel options?

Comparing lifetime cost requires more than sticker efficiency. Note the current fuel source, local electricity and natural gas prices you pay, and planned changes to usage. Ask each bidder for expected seasonal efficiency numbers or run-hour estimates for your home so you can compare operating cost scenarios: conventional gas furnace, all-electric heat pump, or a hybrid approach. Reasonable bidders will explain trade-offs for Ontario’s four-season climate rather than promising a single number. Use recent utility bills to check run-hour assumptions and to see how sensitive your monthly bill may be to different fuel mixes.
5) Do you have indoor air quality or water-system needs that change the solution?

Indoor air quality and water systems change scope and price but are often added as upsells. Note symptoms such as persistent dust, musty or stale air, high indoor humidity, uneven temperatures, hard water scale, or taste issues with drinking water. If you have concerns about filtration, ventilation, a water softener, reverse osmosis, or tankless versus tank water heaters, list those needs up front and ask bidders to separate the cost of comfort or water-quality items from core heating and cooling work. That makes proposals comparable and prevents surprise add-ons during installation.
6) Does each quote show clear scope, warranties, and permit responsibility?

Compare bids line by line for these contract essentials: the exact equipment brand and model, labour warranty and length, manufacturer warranty and who handles claims, permit and inspection responsibilities, a timeline with milestones, and how change orders are priced. Beware vague scopes, unusually low prices with no detail, or high-pressure timelines that demand immediate sign-off. Ask for a sample contract or installation checklist so you can confirm warranty and permit language before signing. Clear wording on who pulls permits and who is responsible for inspection corrections can save time and cost after installation.
7) Is a heat pump a practical option for your home in Ontario?

Heat pumps are now a common choice, but practical suitability depends on house envelope, duct system, and backup heat strategy. Ask bidders about low-temperature performance (cold-climate ratings), whether a hybrid or zoned approach is recommended, and what backup or auxiliary heat will be used. A professional pre-retrofit assessment is essential for whole-home conversions because it evaluates envelope heat loss and distribution efficiency first. In Ontario, discuss seasonal performance, defrost behaviour, and how the system will integrate with existing heating distribution so the quoted solution matches real winter loads.

How to use these checks to compare competing quotes

Score each written quote on the seven checks: give a tick for clear evidence (Manual J supplied, serial numbers photographed, diagnostics shown), a half tick for partial information, and zero if the bidder cannot or will not document the check. Prioritise must-haves such as correct sizing, clear warranties, and permit compliance over nice-to-haves like premium filtration unless you need them. Use total scores plus your local fuel-price sensitivity to shortlist two bidders, then schedule an independent, no-pressure second opinion if you still need clarity. This method keeps comparisons factual and reduces the influence of sales rhetoric.

What to bring to a free SO HVAC second opinion

Gather these items before the visit to make the assessment faster and more useful:

Any written quotes or proposals you received, including scope and equipment models.
Photos of the equipment, including nameplate and serial-number plates.
Maintenance records and filter replacement dates.
Thermostat settings, control wiring photos, and any error messages observed.
Recent utility bills to illustrate usage and fuel costs.
Access to the mechanical room and attic where applicable.

Bringing this packet helps the assessor explain what is required now versus what can wait and shortens the time needed on site.

What to expect from SO HVAC’s free, no-pressure second opinion

SO HVAC describes a four-step, zero-pressure process: you tell them what you were told, they perform an independent assessment, they explain required versus optional work in plain language, and you decide without pressure. Expect a site visit that includes visual inspection, basic diagnostics, and a written summary of findings and recommended next steps. The written summary lets you compare quotes using the seven checks above and decide with confidence.

Local service area and Ontario climate notes

SO HVAC serves homeowners across Ontario, including Mississauga, Oakville, Burlington, Brampton, Milton, Hamilton, Niagara, Cambridge, Guelph, and Orangeville. Ontario’s four-season climate affects sizing and backup-heat choices, so always ask how a recommended solution performs at low temperatures and whether the quoted system needs supplemental heat in extreme cold.

Frequently asked questions

Is the SO HVAC second opinion really free and obligation free?

Yes. SO HVAC states that the second opinion is free with no obligation to buy. Their process separates evaluation from sales so you get an honest assessment without pressure.

How long does a typical second-opinion assessment take and what deliverables will I get?

Expect a site visit that includes inspection and basic diagnostics, followed by a written summary of findings and recommended next steps. The exact duration depends on system type and access to documentation, but bringing quotes, photos, and maintenance records speeds the visit and can reduce time on site.

Do you sell equipment or is the assessment independent of sales pressure?

SO HVAC positions the second opinion as independent and zero-pressure. They evaluate equipment and present what is required versus optional so homeowners can compare quotes confidently before deciding.

Will you evaluate whether a heat pump will work in my home during the visit?

Yes. A professional assessment will review envelope heat loss, duct distribution, and low-temperature performance concerns to determine whether a heat pump is practical for your home or whether a hybrid or staged approach is preferable.
