7 Questions to Ask Before Hiring an HVAC Technician

While you might not know which questions to ask to determine what’s going on with your malfunctioning HVAC unit, you should know which questions to ask the HVAC technician who’ll be servicing your unit. The HVAC repair replacement pros of Legacy Air are here with seven essential questions to ask before deciding on who will take care of you and your heating and cooling needs.

1. Are You Licensed, Bonded and Insured?

You wouldn’t trust your healthcare needs to a physician who doesn’t have a medical license, so why trust your HVAC unit to a company who isn’t currently insured, bonded and licensed? No matter if you need a minor inspection or a major repair, do yourself a favor and only work with heating and cooling businesses that have the required education and experience necessary to be licensed by the state and the insurance to protect themselves as well as you.

2. Do You Have Experience With My Specific Unit?

We also encourage you to work with a company familiar with your brand and type of HVAC unit. Your unit might be older or newer, and the company you choose should know how the system works so there’s a better chance of taking care of the issue the first time and for long-lasting results.

3. Do You Have References?

Just like a potential landlord might ask for references, the same applies to when you’re engaging an HVAC service company. Checking their website and other sources such as Yelp for past and current customer comments will help give you an assessment of the company’s professional capabilities and how satisfied that their customers are.

4. Do You Offer Free Estimates for Replacement Equipment?

When replacing equipment, you are likely to shop around before choosing a company. It’s best to gather estimates from each company you’re considering and compare them to each other, bearing in mind that the lowest estimate isn’t always the best option. See what’s included in each estimate and what might be missing from each and if they offer a warranty on their workmanship.

5. Do You Subcontract Any of Your Work Out?

Unfortunately, some service companies will represent that they do all their own work when they actually often subcontract their work out to parties that may not be properly licensed or bonded. You want to be sure you know who will be providing your service and that you can trust them.

6. Do You Offer a Maintenance Program?

You want complete peace of mind when it comes to your heating and cooling system. Getting a service contract can save you time and money by ensuring your unit is regularly serviced to reduce the chances of avoidable problems later on.

7. How Experienced are the Technicians?

While everyone has to learn sometime, you really do not want a rookie working on your heating and cooling system. Experience technicians will have had exposures to a wide range of service issues and will usually be able to quickly and correctly identify any problems

Making sure your HVAC system works in the Summer

At legacy air we are striving to be the best HVAC company. This means making sure we are known primarily for our customer Service. This is why we have developed this page and several others like it, where we are counting on the concept that if we help you better understand the things you can do yourself, you aer more likely to come back to us for help with the things that might be a little tougher to handle.

Here are some steps you can do to make sure your HVAC systems are running at peak performance capabilities right before the summer season….

1. Most important is to always change your air filters. A dirty air filter can sabotage both the efficiency and longevity of your heating and cooling systems so change them often. This will also help to prevent a more expensive A-line/Indoor Coil cleaning.

2. Spraying down your outdoor/condenser coil. This is a pretty easy task, really. You will want to remove the fan from the top of the unit. First things first, though, switch the service disconnect to the off position or pull the fuse if so equipped. This will prevent the fan from accidentally coming on during the cleaning should the thermostat call for it. There is usually three to four screws holding the fan down. Remove these screws and pull the fan up and lay it upside down on top of the cabinet of your outdoor coil. The wires connecting the outdoor fan motor are usually long enough that you should have no problem positioning the fan out of your way. Take your garden hose and spray the coils off from THE INSIDE OUT. There is also a coil cleaner you can purchase at your local HVAC supply house if you have a dog like mine who uses your coil as his “post”. Once the coils are thoroughly sprayed down you can replace the fan and screws and turn your disconnect back to the on position.

3. Hold that thought. Check the electrical components of your outdoor coil. Go back to the disconnect and put it back to the off position or remove the fuses. You still need to check the electrical connections at your outside unit. Once you are sure the disconnect is off, pull the electrical panel covering your outdoor coils electrical components. Once it is removed you can check for loose wire connections that could cause arcing, grounding, or shorting. Check your contactor for pitting at the points (a pitted or corroded contactor can cause the contactor to chatter or stick). If you have an electrical multi-meter you can check your amp draw on the compressor and the condenser fan motor. Make sure you are getting the proper voltage to your system, both on the high side and low side circuits. If your multi-meter has a MFD setting on it you can check the capacitor(s) to make sure they are within +/- 5% of there ratings. If they are not or they are close to being not within this range than replace them. A failing capacitor can take the motor it is designed to help, out with it when it goes.

4. Check the refrigerant circuit for proper operation. This can get complicated and the method for checking it depends on a variety of things including the type of your metering device, ambient temperature both inside and out, saturation temps and all manner of things. A decent indicator of if your refrigerant circuit is running well is to check your temperature split between your supply air and your return air. Put your wife’s turkey baster thermometer thingy (not sure of the technical name she would call it) in the supply air outlet furthest from your supply plenum. The temperature should be roughly 17-23 degrees different than the reading on your thermostat for indoor air temp.

5. Check the duct connections in your attic for loose or broken connections. A loose connection can cause havoc on your house’s air balance not to mention the loss of efficiency of your system overall. These are usually easily fixed with duct tape or duct sealer available at your local hardware store.

Good Luck and God Bless
