HVAC and Plumbing FAQs

Throughout our 38 years in business, Keith Lawson Services has heard it all. Below are common HVAC and plumbing FAQs. In most cases, you should call a technician, but on some occasions, there are simple do-it-yourself solutions. However, if the job is too complicated, don’t hesitate to call KLS. When you choose Keith Lawson Services for your service company, you can be assured that you will be 100% satisfied with the job — guaranteed. 

If you have any further questions or need to schedule a service call for your home or business, give us a call at (850) 562-2600 or book an appointment online.


Before you call us, be sure that your A/C unit is on, check your filters, check the thermostat for proper settings and check for blown fuses or tripped circuit breakers on the air conditioner unit. Of course, if you’re still experiencing difficulties after taking these steps, contact us and the Keith Lawson Services team will be happy to help.

How often you change your air conditioner’s air filter depends on the type of air filter you’re using; the number of pets and people occupying the home; and the overall indoor air quality. Typically, you should change your air filter every 90 days. If you have allergies or asthma, changing your air filter every six weeks is necessary. If you have a furry family member in the home, you should change your filter every two months to keep the odors and pet hair from building up. If the surface of your filter has a visible coating of dirt, it needs to be changed. When it doubt, call KLS and we’ll be happy to help you decide which filter is best for your home.
No matter what kind of system you have, it’s recommended that you have your air conditioning unit inspected, cleaned and serviced twice a year — your heating system in the fall and your air conditioning checked in the spring. Our Red Carpet service makes it easy for you to get these checkups at a priority attention basis, same-day service if service call is made before noon.
There are several factors that could be the cause of hot air blowing out of your air conditioner. Before scheduling a service call with us, check your thermostat, as you may have accidentally flipped the switch to heat mode. If your thermostat is set to cool and you’re still feeling hot air, you could have a dirty air filter and a dirty evaporator coil. You can change the air filter, but you’ll have to call us to clean the coil. Hot air in your AC unit can also be caused by leaky air ducts, dirty components on your outside AC unit and low levels of Freon/refrigerant. Getting these fixed are best left for the professionals!

A programmable thermostat, like the Nest Learning Thermostat, has many benefits. The Nest Thermostat programs itself and automatically saves energy while you’re away from your home. You can even control it using a smart phone, laptop or tablet and receive safety alerts when your home is too hot or too cold.

Keith Lawson Services is the only Pro Elite Nest Products Provider in the area. If you’re interested in having the Nest Learning Thermostat, or any Nest product, installed in your home, schedule an installation appointment.

When you live in the humidity of Florida, it’s normal to see pools of condensation outside of your outside AC unit, especially on a particularly hot day. However, if you see that your unit has been leaking water for a full day or longer, you shouldn’t hesitate to contact us.

Many factors can play a role in a leaky AC unit, including a dirty air filter; faulty condensate pan; blocked AC drainpipes; frozen coils and a damaged/rusted drain pain. Instead of tackling these complicated problems yourself, leave it to the professionals and schedule a service call ASAP. Call us at (850) 562-2600.

When you know, you know. If repairs are becoming frequent and costly; if you notice your home’s indoor air quality has been poor; if your HVAC system isn’t efficiently cooling or heating every room in your home; or if the HVAC unit is just in poor condition, it’s time to have a new unit installed.

We install high-quality American Standard, Amana and Lennox equipment to the Tallahassee, North Florida and South Georgia areas and will keep your air conditioning running smoothly. Contact us today.

Plumbing FAQs

Just as you do for your HVAC system, you should schedule plumbing maintenance annually. The average household plumbing system is about 15 percent of the value of a home. Getting your plumbing system serviced once a year will ensure it is both safe and efficient and help you avoid future costly repairs.

Sometimes, a little do-it-yourself comes in handy, especially when dealing with a clogged toilet. Most clogs can be cleared with a good plunger and a little bit of elbow grease. Watch this video to see how you can manage the problem.

If you’ve got a stubborn clog or cannot see what’s blocking your toilet from flowing correctly, give us a call at (850) 562-2600. We have a 24 hour emergency line if you wake up to a nasty mess in your bathroom!

A running toilet wastes up to 200 gallons of water per day while racking up your water bill! There are several factors that can cause a noisy toilet. Some common causes include a cracked floater ball, a broken toilet flapper, leaks or a faulty fill valve.

It’s best to avoid jumping on Google for this issue, as the internet contains a lot of misleading information that can cause more harm than good. It’s recommended you call us – no matter what time of day or how big the problem, we’ll get it handled!

Call us as soon as possible. A leaking toilet can waste as much as 80,000 gallons of water each year if left undetected.

Preventing toilet clogs is easier than you think! Flush only what belongs in the toilet: human waste and toilet paper. Diapers, baby wipes and feminine hygiene products should not be flushed! You should also flush only as much toilet paper as necessary. Do not flush large wads with one flush. Keeping the area around your toilet tank clear will also decrease the risk of major clogs forming in your toilet.

If you have a yucky clog that won’t seem to go away, we’re just a phone call away.
