"SAVED MY 84 y.o. MOM'S & MY DAY/WEEK!! Incredible service! Mom's 84 in Summerville, I live in California... Right off the bat, Sammy, the biz owner, responded, within 5 mins of yelp request. He gave me a price that was flat rate and VERY reasonable. Didn't need to set appt to come (days later) to give an estimated (over-priced) bid. (All via yelp msging) I told him I was going to buy new Rheem water heater at Home Depot. He offered to pick it up to save me the delivery charge and not charge more money!$$$ He could do it same day or next AM. I AGREED. Bought unit online from Home Depot in Summerville. Made him the contact pickup person. Sent him the order #. He picked it up. Took out & away the old unit (rusted out bottom) and put in brand new unit / cleaned up the mess) this was all done by 7pm on the SAME DAY!! I didn't order the unit until almost 1pm. He msged me a chase bank credit card payment link to pay. Easy & secure. My Mom was VERY HAPPY & GRATEFUL to Sammy at KLC. I was so HAPPY with how it all turned out I asked him if he had Venmo or cash app and sent him more money $$ directly!! Very grateful... DEFINITELY CHOOSE SAMMY if you need REAL HELP and need a good Friend in the Plumbing or HVAC BIZ."

Heating and air conditioning services FAQs

Knowing how long your existing HVAC units can last is essential to determine if you need a repair or replacement. Typically, most modern air conditioning units can last between 15 to 20 years, and most furnaces can work properly for 15 to 30 years. If your HVAC system is on the older side and you decide to replace one unit, it might make sense to replace both simultaneously to save on costs and future hassle.

While different HVAC contractors might offer higher or lower prices than competitors, the best time to replace your HVAC system is when customer demand is low. The beginning of summer and the beginning of winter bring the most demand for HVAC systems, so if you can, consider replacing your HVAC units in the early spring or fall. Many HVAC companies offer special off-season coupons that help lower the overall cost.  

The average cost to hire an HVAC contractor is between $50 and $150 per hour if charging hourly. However, some HVAC contractors will charge a flat fee by the type of service they are performing—for example, an inspection can cost between $150 to $500. Keep in mind that emergency repairs—which are made after business hours or around major holidays—generally cost more than scheduled repairs.

Yes, most states require HVAC technicians to be certified, and for good reason. Hiring an unlicensed HVAC technician could lead to poor quality work, costly future expenses, and potential code violations. 

As you browse our pro listings, take note of the “Angi Approved” badge. Angi Approved businesses meet our standards for certification which include: 

  • The owner, principal, or relevant manager passed a criminal background check

  • Required to have applicable state and local licenses

  • Maintain an average star rating of 3.0 or better on our network, if they have at least one review

  • Paying to advertise their services

  • Meeting any other eligibility criteria required by Angi

Keep in mind licensing is different from certifications. A license is a legal requirement to operate a business, while certifications are voluntary.

The average cost of HVAC repairs is around $350. However, that price can be as low as $100 or as high as $2,000 or more, depending on the repair. For example, replacing a capacitor is a relatively inexpensive repair, ranging from $100 to $500. However, a compressor repair is a more expensive repair, ranging from $750 to $2,000.
