HVAC Contractor Repairs in Des Moines
Keeping up with repairs is one of the best ways to ensure that your HVAC system lasts as long as possible. Ignoring telltale signs may seem ideal at first. However, disregarding these warning signals will only end up costing you more in the end.
One of the most obvious signs is low air pressure. Have you noticed that it’s taking longer for your home to cool or heat up? You could be experiencing poor airflow. Other than a clogged filter, you could also be dealing with leaky ducts, dirty coils, blocked ducts, or outdated parts.
Short cycling is another issue you shouldn’t overlook. When a system cuts off and on frequently, it doesn’t get a chance to properly heat or cool the space. This causes the unit to work much harder than necessary, eventually leading to unexpected failure. Along with short cycling and low air pressure, you should also pay attention to strange noises and foul odors.

Heating and Cooling Company Installations
Even when you stay up-to-date with repairs, there may come a time when you must replace your HVAC system altogether. Before you purchase a new system, you should first decide which option is best for your home.
The size of your space is one of the first things you want to consider. If your home is 1,000 square feet, for example, you would likely benefit from a unit that is at or around 1.5 tons. Ductless mini-split systems are ideal for smaller buildings. For larger homes, dual-zone systems are sufficient. Heat pumps provide a more energy-efficient option. Because heat pumps transfer heat instead of creating it, their impact on the environment is relatively minimal.
In addition to the size of your home and energy efficiency, there are several other factors you should consider:
- Your local climate
- The layout of your home
- If there’s existing ductwork
- Your budget

HVAC Company Maintenance Benefits
Even after installing a brand-new unit, you will still need to schedule regular maintenance services. Routine maintenance provides a variety of benefits, including better air quality, lower energy bills, and lower repair costs. Because maintenance allows technicians to tackle problems early on, your system is more likely to live out its intended lifespan.
