Heating Repair and Replacement Services
Customers often wonder whether repairing an old heating unit or installing a new one is more cost-effective. To determine the answer, there are several factors to consider. These include the unit’s age, frequency and severity of repairs, the system’s energy-efficiency, your budget, and your comfort preferences. A well-maintained furnace will usually last between 15 and 20 years.
However, if your unit is more than 10 years old and breaks down frequently, it may be better to replace it. Older furnaces are generally far less energy efficient than newer models. If your utility bills are high, a new, energy-efficient model could pay for itself rather quickly.
Types of Heating Systems
Gas is the most common heating fuel, and gas furnaces are usually part of ducted, forced-air heating systems. If your home does not have ducts, ductless heat pumps offer a versatile and efficient alternative. If you’re in the market for a new heating system, we can recommend one that is compatible with your lifestyle, budget, and comfort requirements. There are many systems available, including:
- Furnaces and central heat pumps
- Ductless mini-splits and multi-splits
- Hybrid heating systems
Importance of Proper Heater Installation
Our experts always adhere to the highest industry standards when sizing new heating equipment. Improperly sized units use more energy to operate, break down more often, and experience shorter system life. Undersized units may run longer and struggle to provide the warmth needed for comfort. Oversized units cycle frequently, which can wear out components, cause temperature fluctuations, and waste energy.
Our goal is to provide reliable comfort at a fair price for all of our customers. As a Daikin Comfort Pro, we can honor the manufacturer’s warranties and guarantees. We always strive for 100% customer satisfaction, an important element of our business ethic.
