"I had purchased a new HVAC for installation in my home. There were challenges to getting the cooling unit to function as well as running new wire. The job took several visits to trouble shoot and complete. The service staff, Ian Bryan, and Will were cordial and professional throughout the process. And the manager, Eric, was assertive in contacting me and trying to schedule a final service appointment to get the issues resolved so the system would function properly. This company is definitely motivated and intentional to keep customers happy and satisfied. They are tidy and clean up afterwards. I would use this company again based on K&K's bottom line of doing the right thing when there are complications."

"The technician arrived in the scheduled time given (10-11 am).  He was clean and well spoken.  We went down to the basement where he told me what he was going to do to service the air conditioner.  He discussed filter options with me and made sure I had the correct size to purchase new filters when necessary.  He spent about 45 minutes cleaning and servicing the unit.  He explained what we could do to keep our upstairs cooler.  (Our home is holder and doesn't have return exchanges for the heating/cooling).  This company also honored a coupon that was on Angie's list (though it had expired)...Love that!!  I would definitely use Brandon Heating and Cooling again.

"I could not be happier with Sal's Heating and Cooling. I bought a new furnace from Sal's, and everyone I dealt with was professional, knowledgeable and prompt. This included the salesman, the installers and the technicians who came back to get rid of a 'pop' I was hearing in my ductwork. They all made sure I was happy with the work that was done.. A very conscientious company. I will definitely recommend Sal's Heating and Cooling to anyone who needs HVAC services!"

"I really am a stickler for good customer service and Sean fit the bill. He contacted me right away and we had an appointment within a week. Sean and his helper arrived and spent 2 hours cleaning our HVAC system, registers, and grills after a construction project. The environment was definitely cleaned from most of the drywall dust and I could tell the difference. I will be using him in the future."

"Productive was recommended to me by a professional HVAC contractor. He said that he had been recommending them for 20 years. He was right to do so, the team from Productive was excellent. I have a 100 year old house in Lakewood, OH. The ducting had been replaced with a new furnace in 2000, and I felt that it was time for a cleaning. There are a lot of runs to all of the rooms in the house. Even so, the Productive team arrived on time, were very clean and professional, and got the job done in just over 2 hours. I was very impressed. It was a rainy day, but the techs made sure to cover their shoes every time they came back into the house. When the job was completed, you wouldn't have even known they had been there. The furniture was all placed back where it was, the basement was perfectly clean, and the house smelled better than it did before the cleaning. Thanks Productive! Highly recommended!"

Heating and Air Conditioning FAQs, answered by experts

Unfortunately, a freon leak will persist even when your AC unit is off. The freon in the AC unit is under pressure no matter the status of the system, so it will continue to drip through the leak even when you shut off the entire unit. It will continue to leak freon until it’s completely empty.

The cost of annual maintenance depends on the type of HVAC system you have. AC service typically costs an average of $200 but ranges from $100 to $550. If your system needs repairs, the price will vary significantly depending on what needs fixing. However, addressing the issues as they arise can prevent further damage to your unit and keep it operating efficiently for much longer.

Deciding whether to replace just the AC coil or the entire system depends on the age of your unit and the overall cost. Replacing a coil is less expensive than a full system replacement, but it can still be a pricey repair. If your HVAC system is relatively new and still under warranty, or if the replacement cost is significantly lower than a new system, replacing the coil can be a worthwhile investment that restores efficiency and extends the unit's life. However, for older systems (nearing the end of their 10-15 year lifespan) or those with extensive damage, it is often more cost-effective to replace the entire AC unit. Mismatched coils in an older system can lead to inefficiency and future breakdowns, so a full replacement ensures optimal performance and avoids further costly repairs.

There are plenty of different not-so-great sounds to hear from your air conditioning unit, like squealing, grinding, water running, excessive gurgling, banging, and clanking. Each of these sounds can indicate a different malfunction with your unit, so it’s important to have a professional assess the problem before it gets worse.

If both your furnace and AC unit are more than a decade old, it may be a good idea to replace both of them. However, your furnace can last up to three decades, and your air conditioner can typically last up to 15 years, so consulting with a pro before deciding to replace both of them is best. If it’s before that time limit for each, you can fix many problems with repairs or just replace one.
