Ask Angi: What to look for in a furnace inspection

  • 0

Regularly replacing air filters is a vital part of HVAC maintenance.

Even as hot weather covers most of the nation, chillier fall days may be closer than you think. Right now is the perfect time to check up on your heating system and make sure it’s ready for fall and winter.

HVAC pros are already getting their schedules filled up, so if you want an inspection, call them sooner rather than later. This gets your system prepped with plenty of time, and you can complete any repairs before you really need the heat. The last thing you want is to fire it up in October and get nothing.

You should hire a licensed HVAC contractor to inspect your system twice a year: before starting up your air conditioner and before starting up your heater. Heating pros will check all the vital systems and make sure the unit is reliable and safe. They’ll also take a look at the cooling side, so if either component of your system is developing problems, this inspection can catch small problems before they become big (and expensive) ones. This inspection will generally cost about $100. If you have a service contract with an HVAC pro, there’s a good chance twice-yearly inspections are already included.

The pros know what to look for, but you can also take steps to evaluate and protect your system. Take a look and make sure the system is free of residue or soot. Inspect duct work for loose connections, and seal any openings.

Ensure proper clearance by removing items from around the furnace. You don’t want to block airflow, and you definitely don’t want combustible items around it. Make sure all windows and doors in the house are sealed properly. Sealing your home from air infiltration keeps cold air out of the house, which can help prevent high utility bills.

Clean the areas you can reach with a vacuum and brush attachment. Getting rid of debris on filters and coils will help the air flow. Take care not to damage or jar any components, though. You only want to address the surface issues; getting into the system’s internal areas is best left to a licensed pro.

Replace your furnace’s air filter. Do this frequently (usually monthly, but pleated filters will last longer), but it’s most important when the system switches from heating to cooling and vice versa.

This checkup is a good time to take stock of your safety detectors as well. Make sure carbon monoxide and smoke detectors have up-to-date batteries, and test them.

Q: Tim, it's a very long story, and don't think I'm crazy. I'm building a new home and wondering if I can install all the electrical wiring myself. It's not a big home, but it's got all the things going on you'd normally have in a home, including quite a few three- and four-way switches. I've watched a bunch of online videos, I've read a few authoritative books and I'm feeling pretty confident. What am I missing? What would you do if you were me? —Margo F., Albany, Ga.

I have no clue how many new roofs are installed in the USA each year, but it’s got to be in the hundreds of thousands. Perhaps a new roof is in your future or in the next few years. If so, you’d be wise to read up on the topic at before it’s time for you to meet with a roofer.
