Question 7

Question 8

What is included in a maintenance plan?

Accepted Answer

Our maintenance plans include seasonal tune-ups (spring and fall), filter replacement, full system inspections, and efficiency checks. Regular maintenance helps prevent costly breakdowns and extends the life of your equipment. Maintenance plan customers also receive priority scheduling.

Question 9

How often should I have my HVAC system serviced?

Accepted Answer

We recommend having your HVAC system professionally serviced at least twice a year — once in the spring before cooling season and once in the fall before heating season. Regular maintenance keeps your system running efficiently and helps catch small problems before they become expensive repairs.

Question 10

How do I know if I need to repair or replace my HVAC system?

Accepted Answer

Generally, if your system is over 10–15 years old, requires frequent repairs, or your energy bills have increased significantly, replacement may be more cost-effective than continued repairs. Our technicians can evaluate your system and give you an honest recommendation.

Question 11

How long does a typical HVAC installation take?

Accepted Answer

Most residential HVAC installations can be completed in one day. Larger or more complex systems may take longer. We'll give you a clear timeline before we begin any work.

Question 12

What size HVAC system do I need for my home?

Accepted Answer

The right system size depends on your home's square footage, insulation, number of windows, and other factors. An undersized or oversized system can lead to inefficiency and comfort issues. Our technicians perform a proper load calculation to recommend the right size for your specific home.

Question 13

Why is my air conditioner not cooling properly?

Accepted Answer

Common causes include a dirty air filter, low refrigerant, a frozen evaporator coil, a faulty compressor, or a refrigerant leak. We recommend calling a professional rather than attempting to diagnose or repair these issues yourself. Call us at (423) 663-3175 and we'll get to the bottom of it.

Question 14

Why is my heating system making strange noises?

Accepted Answer

Banging, rattling, squealing, or grinding noises from your heating system can indicate loose components, a failing motor, or other mechanical issues. Don't ignore unusual sounds — they often signal a problem that will get worse and more expensive if left unaddressed. Give us a call and we'll diagnose it.

Question 15

How do I schedule a service call?

Accepted Answer

You can call us at (423) 663-3175 or text us at (423) 663-7042, or send us a message through our Contact page. We'll get back to you promptly to schedule a convenient time.

Question 16

Do you provide free estimates?

Accepted Answer

Yes! We offer free estimates on new HVAC system installations. For service and repair calls, a $50 service call fee applies. Depending on the issue, an additional diagnostic fee may be required, which will always be discussed with you upfront before any work begins. At Sexton's Heat & Air, Inc., we believe in honest, transparent pricing with no surprises — so you'll always know what to expect before we start the job.
