At The HVAC Detective, we’re not your average heating and cooling company — and that’s exactly the point. We believe a successful service business only needs three pillars: The Client • The Technician • The Dispatch Team Everything else? Just noise. While the big corporate HVAC companies are weighed down by layers of management, oversized fleets, expensive offices, and bloated overhead, we’ve chosen a different path. By keeping our operation lean and efficient, we keep our prices fair and our focus sharp — where it belongs: on you, the customer. We’re here to provide an alternative to the corporate marketing hype, the inflated “specials,” and the endless upsells. No gimmicks, no hidden fees, no sales pitches Our Promise • Honest pricing without the corporate markups • Expert technicians who solve problems, not sell you on new ones • Transparent communication from dispatch to completion We detected and corrected the first time!

"Straight forward and honest. Did an awesome job."

"I have a dual zone system and the air handler/heat pump unit on the 2nd floor was blowing hot air. I immediately looked up HVAC service in the Bel Air area and came upon Comfort Air. I initially chose this company based on the good reviews. I was told by the technician that based on the age of the unit and problem it was more cost effective to replace the unit instead of making a temporary fix. I agreed and after entertaining some estimates I chose Comfort Air. We negotiated a very reasonable price along with a quality unit. The installers were very professional and completed the work in about 4 hours. I would highly recommend Comfort Air for any Heat and Air Conditioning needs."

FAQs for central a/c service or repair projects in White Marsh, MD

A condenser fan motor is a crucial part of your air conditioner that prevents the compressor from overheating. It pulls heat from your AC unit to cool the refrigerant moving through the condenser coils. This allows your system to blow cool air and keeps everything running smoothly.

The most common causes of AC fan motor failure include loss of lubricant in the system due to overheating and a rusted or leaking run capacitor. Poor lubrication can also cause failure in the belt drive, which may impact the AC fan motor. Weather and electrical components can also affect your AC. For example, a storm could send water into your motor windings and damage the internal components.

Air conditioner fan motors last about 12 years on average, though they can last longer if maintained well. This includes keeping them clean and cooled as needed with annual air conditioner checkups. Routine maintenance is essential to catch AC fan issues early. An HVAC inspection can cost between $70 and $500, while AC cleaning services may range from $100 to $400.

A broken AC fan motor may need replacement because this part usually can’t be repaired. Several things indicate it’s time to replace your AC fan motor, including buzzing noises, a constantly running fan, unusually high energy bills, or an aging system. If you notice these signs, call an HVAC pro for help before the faulty motor starts to strain other parts of the AC system.

There are clear warning signs of a bad AC fan motor, including unusual interruptions in the fan operation. The motor might be malfunctioning if you hear weird noises like grinding or rattling or if the fan continues to spin when the unit is off. These indicators compromise your AC’s cooling performance and increase your energy costs. Addressing these issues immediately by contacting a trusted HVAC professional prevents further damage and safeguards your HVAC's efficiency.

Replacing your AC fan motor takes a professional one to four hours. The technician will start by assessing your system and safely removing the damaged motor. If a new part needs to be ordered, it might take a few days. Once the part is available, your pro will install it properly and make sure your system is running smoothly.
