You wouldn’t wait until it snowed to buy a snowblower or until it rained to buy an umbrella.
It is constantly wise to try & make purchases when items are not in demand.
I bought my sodmower in late fall, when it was at a clearance price. It was still a current machine, however it was 35% off the proper price. This same reasoning can be taken into consideration when buying a current Heating, Ventilation, & A/C system. If you are looking to substitute or purchase a current boiler & it is the middle of November, you are going to pay a premium price because they are in high demand. Heating, Ventilation, & A/C dealers are undoubtedly tied up in the winter season & Summer months. They can charge whatever they like because they know that you will be willing to pay the price. It is better to contact them in milder weather like Spring & fall. They are usually not as tied up while in this time & many have specials going to entice current buyers. Your Heating, Ventilation, & A/C system in your house is one of the greatest investments that you make. If you are able to take luck of free installation, rebate offers, & percentages off, why not. Occasionally, you can even purchase last year’s model, even though it is still new, & save half off because they want it out of inventory. My pal and I all labor undoubtedly hard for our money & sometimes have to save for years to afford a current system. Make every dollar count & shop around. Also, make sure to purchase at the right time of year whenever possible.
