It’s a sad fact: often, new HVAC systems are purchased only after it’s stopped working and cannot be repaired. A regularly checked and conditioned unit will often give signs that it’s on its last legs. It could be: high cooling and heating costs, lack of warmer or cooler air, making various “I’m getting old” noises.
Do you take a chance to see if you can get another year out of it? Just be mindful that if it goes, you could be in the middle of a terrible cold snap or in full on summer mode. And a new unit isn’t something you can replace same day.
So when is the best time to buy a new system? The answer you may not want to hear is while it’s still working.
However, if you insist on waiting for it to go belly up, please do your homework before hand so you can be smart about what you’ll be getting. Consider shopping around when you know your unit is still working. Three factors to keep in mind:
1: The right size: Just like Goldilocks’ bed, you don’t want one that’s too small or too big, but rather one that’s just right.
2: Check your current ducts. Get a pro to look around to be sure they’re efficient and in good working order.
3: The right contractor: Referrals! Referrals! Referrals! Just because someone comes cheap does not mean they’re the right one for the job.
Once you pick a new system, you’re just getting started with energy costs. You might save on the purchase, but if you’re not getting the best energy use possible, you’re spending way more than you should. A new unit can last 12 to 20 years. If you’re wasting 10% per month, that could prove very costly in the end!
