Question 1

How do I compare HVAC quotes?

Accepted Answer

•

The best way to compare HVAC quotes is getting a few detailed quotes from local companies with good reputations. Then, go over the quotes line by line. Protect yourself by insisting on in-person estimates that include equipment manufacturer names, model numbers, SEER ratings, amounts and numbers of materials, details of warranties on equipment and labor, and other specifics.

Knowing the exact equipment and materials is the only way that you can fairly compare quotes. Quotes that are much lower than others can be a sign that the company isn’t providing the best quality service or materials.

Question 2

What are the disadvantages of using heating oil?

Accepted Answer

•

Using heating oil to heat your home has its advantages, but it also has its disadvantages.

Consider these drawbacks before installing a heating oil system:

Heating oil prices fluctuate frequently
Risk of oil spills or leaks
Produces more air pollution and soot compared to a gas furnace
Regular maintenance required for equipment
Need to reorder heating oil consistently to avoid running out

Question 3

What are common issues with boilers or radiators?

Accepted Answer

•

Common problems include leaks, low pressure, and inefficient heating. Regular maintenance prevents many issues.

Question 4

What is the most common rule used for HVAC load calculation?

Accepted Answer

•

A common HVAC rule is that for every 500 to 600 square feet of living space, you need 1 ton of heating or cooling capacity. Now that you know this common rule, you also need to know that it isn’t very accurate, and a dedicated pro wouldn’t use it for your home. If you talk to a pro who won’t or can’t perform a proper Manual J calculation, consider hiring someone more thorough.

Question 5

How long does it take to replace a boiler?

Accepted Answer

•

It can take anywhere from four hours to three days to replace a boiler with a new one. How long your particular boiler installation takes will depend on whether you need a gas line installed and if you’re switching to a new boiler system.

Replacing a combination boiler or standard boiler with the same system should only take four to six hours. Meanwhile, switching from a conventional boiler system to a combination boiler system could take a few days.
