Yes. You should expect to pay a diagnostic fee to cover the cost of the technician's visit, the diagnosis of your air conditioner's problem, and a quote for the repair options. This fee is waived if repairs are completed the same day as the appointment. You will be advised of the issue along with recommended options to correct it, which may include a system replacement if your unit is old or significantly damaged. If you decide to replace the system, the diagnostic fee will be credited toward your replacement purchase.
The price to repair your HVAC system depends on what is wrong with your system. We've outlined some common problems and other factors that could determine how much you pay for repairs in our HVAC Service Cost Guide.
Yes. Our local professionals can handle all of your heating and cooling repair needs including service for your furnace, air conditioner, mini split, heat pump, air handler or boiler.
While there's nothing you can do to guarantee your air conditioner or furnace will never need repairs, there are ways to take better care of your system. Changing out the air filters every 3-6 months, making sure nothing is obstructing or interfering with the outside unit, and keeping all vents unblocked in well-used rooms will help keep your air conditioning and heating system operating efficiently.
Start with your utility company; they can help a great deal. Comparing previous bills isn't always a good measure, as the weather is never exactly the same month to month. Instead, if you take your energy bill and divide it by the square footage of livable space in your home, don't count areas like unfinished garages or basements — you can calculate how much you are spending to heat or cool each square foot of your home. Your energy provider can tell you what the average cost per square foot is in your region for that same period of time so you can compare apples to apples.
Sometimes a heating and air conditioning system just needs to be repaired rather than completely replaced. You may need air conditioning repair services if there is leaking around the outside unit, the air coming into the house isn't hot or cool enough, the unit is short-cycling or constantly turning on and off, using the system is consistently resulting in higher-than-normal energy bills, or if there is excessive noise during startup and operation.
Even if your air conditioning unit is still working, depending on the type of system in your home today, you could recoup your investment in a new system in as little as three years. However, that doesn't mean that your system needs to be replaced. Furnaces, air conditioners, and other heating and cooling systems have made tremendous gains in efficiency over the past five years, so if you have an older unit, it is worth taking a look at whether or not a repair is the best investment.
The most common issue in HVAC systems is a dirty air filter. Replacing air filters regularly may be easy enough, but it's just as easy to overlook or forget. With time, air filters can collect enough dust and debris to clog the filter, significantly reducing airflow and increasing the strain on your system. A dirty air filter can reduce indoor air quality, increase your energy bills, and reduce the lifespan of your system.
The most common point of failure in an HVAC system is the capacitor. The capacitor is a device that stores energy for a short time, distributing that power to other system components as necessary. It helps start components like the motor or fan and keeps them operating smoothly.
The "$5000 rule" is a simple guideline for determining whether you should repair or replace your HVAC system when your system is having issues. All you need to do is take the cost of the repair and multiply it by the system's age. If the result is less than $5000, it's probably best to go forward with the repair. If the result is more than $5000, you should probably replace your system instead.
