Stay Cool & Save Money This Summer!
Spring is the perfect time to schedule an AC tune-up before the summer heat kicks in. Regular maintenance ensures your system runs efficiently, preventing breakdowns when you need cooling the most. A professional tune-up includes cleaning condenser coils, checking refrigerant levels, replacing filters, lubricating moving parts, and testing your thermostat. These small adjustments can significantly improve your system’s performance, extend its lifespan, and lower energy bills.
Fight Spring Allergies with Better Indoor Air Quality
As allergy season arrives, improving your indoor air quality is essential for a healthier home. HVAC upgrades like air purifiers, UV light systems, and high-efficiency air filters can help remove airborne allergens, bacteria, and viruses. Spring is also a great time to check humidity levels—adding a dehumidifier can prevent mold growth and keep your home feeling fresh. Simple steps like replacing air filters regularly can also make a big difference in breathing cleaner air.

Is Your AC Ready for Summer? Check Your Refrigerant Levels Now!
Low refrigerant levels can cause your AC to struggle, leading to inefficient cooling and higher energy bills. A professional technician can check your system’s refrigerant levels, inspect for leaks, and recharge it if needed. Addressing these issues in the spring ensures your AC is ready to handle the heat without overworking itself, helping you stay comfortable all summer long.
Upgrade Your Comfort with a Smart Thermostat
Upgrading your thermostat in the spring can make a big difference in comfort and energy savings. A smart thermostat learns your schedule, automatically adjusting temperatures for efficiency while keeping your home comfortable. Even a simple recalibration of your existing thermostat ensures accurate temperature readings and prevents unnecessary energy use. With remote control options, you can adjust settings from anywhere, helping you stay cool without high utility bills.

Here are some of the most frequently asked heating and air conditioning questions we receive from our customers. Click below to learn the answers to some of our most FAQs here at Duncan Heating & Air Conditioning:
To keep your HVAC system running in tip-top shape, we recommend a maintenance appointment twice a year (once for heat, once for air conditioning). This way, an Oliver technician can check your filters, coils, wiring, housing, motor, and more to make sure you’re getting the most out of your system.
If your HVAC system requires constant repairs, is 15 years or older, or can’t heat or cool your home properly, we recommend you replace it. When an HVAC system ages, it doesn’t operate as efficiently and could actually end up costing you more money than it should.
The air filters are one of the most important components of an HVAC. They catch all the airborne particles that you don’t want floating around your home and in your lungs. Once they become full or clogged, your indoor air quality becomes compromised and the lack of airflow can lead to system breakdowns. It is best to replace your air filters about every three months and more often if you live with a smoker or someone with allergies or asthma.
HVACs are not one-size-fits-all. If your unit is too big for the home, it will pump out more air than needed, causing higher bills and an increase in condensation which can lead to mold and algae growth. If the unit is too small, it will become overworked and your home will see uneven temperatures. Your HVAC professionals will help you determine the correct size unit for your home as you begin the process of a new installation.
A heat pump is a part of the heating and cooling system which is installed outdoors and pulls in air to heat or cool your home. They are more eco-friendly than a furnace as they do not burn fossil fuels, require minimal maintenance, are long lasting, and can both heat and cool your home.
We wouldn’t say maintenance appointments are important. We’d say they are ESSENTIAL! By scheduling these visits from your technician, you’re setting your HVAC up for a successful season of heating or cooling. The technician will clean your unit and replace your air filter, improving your indoor air quality. They will also be able to spot the warning signs of a potential future breakdown and solve them before they cost you down the road.
HVAC, which stands for Heating, Ventilation, and Air Conditioning, is an all-encompassing term when it comes to talking about your heating and cooling system in its entirety. While the world of HVAC might seem complicated, it doesn’t have to be confusing for homeowners. Give the Duncan Heating & Air Conditioning team a call for any HVAC service needs you may have!
