At Mechanical Heating, Cooling & Electrical, our team walks Dearborn Heights homeowners through each of these before recommending a system.
01What Efficiency Rating Should a New Boiler Have?
Ask for the boiler’s AFUE (Annual Fuel Utilization Efficiency) rating before agreeing to any installation. This number tells you what percentage of fuel becomes usable heat versus what escapes as waste.
According to ENERGY STAR, certified gas boilers carry an AFUE rating of 90% or higher, roughly 6% above the federal minimum standard. Older boilers often run in the 65-80% range, so upgrading to a certified unit through residential boiler installation can meaningfully lower monthly fuel costs.
At Mechanical Heating, Cooling & Electrical, we install several gas-fired boiler options, including models with AFUE ratings of 82%, 84.4%, and 90%, as well as high-efficiency condensing combi-boilers. We can help homeowners compare available options based on their home’s heating needs and comfort goals.
02How Do I Know What Size Boiler My Home Needs?
Ask your contractor to calculate your home’s heat loss, not just measure square footage. A boiler that’s too large cycles on and off frequently, wasting fuel and wearing out parts faster.
One that’s too small runs constantly and still can’t keep the home warm on the coldest days. A proper sizing assessment accounts for:
- Square footage and ceiling height
- Number and quality of windows and doors
- Insulation levels in walls and attic
- Local climate and design temperature for Dearborn Heights, MI
We complete this assessment on every boiler installation project in Dearborn Heights, MI, before recommending equipment, since guessing on size tends to cost homeowners more over time than the installation itself.
03Is Gas or Oil the Right Fuel Type for My Home?
Ask whether your home’s existing infrastructure supports gas boiler installation or whether you’d need line work first. Gas boilers typically reach higher AFUE ratings than oil units and cost less to operate month to month, but the right choice depends on what’s already run to your home and local utility access.
If gas service isn’t currently available, a contractor can walk you through what conversion involves before you commit.

What Warranty Coverage Should I Expect?
Ask specifically what’s covered, for how long, and whether labor is included, not just parts. Warranty terms vary widely between manufacturers and can run from one year on basic components to a lifetime limited warranty on the heat exchanger for premium units.
Get this in writing before installation day, and confirm whether the installing contractor’s workmanship is separately warrantied.
05How Do I Compare Total Cost Versus Long-Term Savings?
Ask for the installed cost alongside an estimate of annual fuel savings, not the equipment price in isolation.
A higher-efficiency boiler often costs more upfront but can pay back the difference over several years through lower gas bills.
Homeowners planning to stay in their home long-term generally see the best return from investing in a higher AFUE system during boiler maintenance services or a full replacement.
06FAQ
