How often should I replace my Air Filter?

Air filter replacement is essential for the smooth and efficient operation of your HVAC system. However, the optimal rate of replacement differs depending on several factors, including air filter type, HVAC model, home size, season, and occupancy. Nevertheless, all air filters should be ideally replaced every 30-90 days for optimal performance.

What is the difference between a Furnace and a heat pump and which is right for my home?

The primary difference is that a furnace only heats your home while a heat pump can be used for both heating and cooling the indoors. However, it is essential to note that heat pumps may not provide adequate warmth during extremely low temperatures. Therefore, investing in a furnace would be better if you reside in an extremely cold area.

What causes my home to have uneven heat, warm and cooler areas?

There are several factors that can lead to uneven temperature in your home. This primarily includes poor airflow in the HVAC system, inadequate insulation, or ventilation. There could also be restricted airflow between the vents and furnace or poorly installed ductwork. Sometimes, old or smaller HVAC units may also contribute to the issue. 

How do I find the best HVAC Service provider?

When choosing an HVAC service provider, it is important to look at a few crucial factors. This includes credibility, fee charges, experience, and skills. Make sure to go through online reviews and projects to make an informed decision. Airdoctor, for instance, has years of experience and a reliable work record. 

What is an Energy Efficiency Ratio?

Energy Efficiency Ratio is used to measure a heating or cooling equipment’s ratio of heat output to power input. In other words, it measures the efficiency of the cooling or heating system against the total energy it consumes. The higher the ratio of your unit, the more energy efficient your system is. 

What are the benefits of a programmable thermostat?

Programmable thermostats come with adjustability features that allow users to adjust temperatures based on a pre-set schedule. It is one of the best ways to save money and make your system more energy efficient. The device also comes with automation technology that supports user comfort, optimizes the system, and provides consistent temperature.   

Why does my furnace make a loud noise when it is turning on?

There are commonly two reasons that may cause your furnace to make a loud noise when turning on. First, there could be a problem with the ignition system. Known as delayed ignition, several factors may be at play and should be addressed by a professional. Alternatively, static pressure in the ductwork may also contribute to the problem. 

Why is my furnace blowing cold air?

There are several reasons why your furnace may be blowing cold air. The most common reason is dirty or clogged air filters. Alternatively, issues with the flame detector, gas supply, pilot light, or condensate lines can also cause your furnace to blow cold air. For a thorough inspection, ensure to seek professional assistance. 

What is an HVAC maintenance contract and how does it work?

An HVAC maintenance contract refers to the fee paid to a service provider for guaranteeing routine maintenance of the HVAC system. These contracts are an excellent way to ensure your HVAC is cared for all year round. These are usually annual plans that are charged monthly or yearly. 

Why does my air feel drier in the winter?

It is common for the air to feel drier in the winter. This is primarily because cold winter air holds less moisture compared to warm air. Any moisture is also quickly sucked in due to low humidity levels. Installing or optimizing your HVAC system or investing in a humidifier are excellent ways to combat dry winter air.
