"I had three companies come to make bids on adding a whole house air filter to my Heating and AC system... Bob Jenson was the only one that actually listened to me, the only one that looked at my whole set-up in the whole house and attic, and therefore the only one that found problems that needed to be fixed and that when fixed would improve the air quality in my home. As a result I do not need the whole house air filter system and I saved A LOT of money. I immediately switched ALL my heating and AC work to Bob Jenson even though I have been with another well-known local company for over 20 years (they did not listen well either, did not see the problems that needed fixing, most of which had been caused by them in the first place, and offered a multi-thousand-dollar bid for a whole house system.) The work included replacing registers in three rooms, encasing a big pipe in my furnace that was shedding fiberglass from insulation right into my air system, and other small issues that are too many to mention here. One week later, in a completely unrelated manner, my AC stopped working. Bob Jenson was able to send someone the next day even though they were booked, and that person first thought I needed a new pump but then discovered a clogged tube that he used tanked oxygen to clear, and he solved my problem. Again, excellent diagnostics and lots of patience. All the Bob Jenson staff and workers whom I have interacted with and who did the work at my house were exceedingly professional, punctual, neat, thoughtful, and smart."

"Michael was knowledgeable and very informative. The installers were competent, outstanding, and courteous. Aire Care’s bid was more budget friendly compared to other major local companies. The crew promised to get installation done in 2.5 days but completed the work in 2 days with an additional install. All in all, we would go with AireCare Heating and Air any day. We highly recommend AireCare Heating and Air."

"I had used Ed before with my other house. I recently hired him to clean the dryer duct at my other house. When he moved the dryer, he saw that there was a lot of lint in the body of the dryer (a fire hazard). Because he could access it, he cleaned it all out as well as the duct. The air flow is perfect. I recommend Ed and Air Duct Professionals highly. I have used his company two times, and I am extremely satisfied."

"Technician Angel came on time. He first cleaned our HVAC unit, checked the wirings & parts & performed tests to ensure the unit is running according to standards. He inspected the Air ducts, vents even the attic. He explained everything and showed us the pictures that he took & the results on HVAC heating and cooling tests that were done. Overall a very good job done by Technician Angel I told him to come back after 6 months. Already recommended Airtime Heating & Cooling to my neighbor. 5 STARS"

"Very pleased with professionalism, quality and price. James, Keith and Quincy completed Al elements of heat and air new installation on time and to specifications. They communicated with us well about every step of the process. It was nice to have someone come into the home and just complete the work without any issues. Owner Michael was very clear without sales hype. Strong background and understanding of home needs."

"Pat and Tom installed a 5 ton heating and AC unit in my garage/workshop, last summer, and now I can make saw dust 7/24 all week long. Their work was exceptional. Service after installation was done without question. Pat replaced a part in my electrical panel that was defective. Professionalism, installation was exactly what I needed, based upon the size of the garage/workshop area I work in. Service after installation was right on. I would highly recommend R&C heating and air, without question."

Air Conditioning questions, answered by experts

Yes. Return air vents are responsible for gathering and pulling in the warmer air. Once they draw it in, your system conditions the air by removing the warmer molecules from it, allowing your air conditioner to dispense the cooler air back into your home. Not only does this create a more comfortable environment for you, but it also keeps your air conditioner from overworking, resulting in lower energy bills. 

When deciding whether to repair or replace your air conditioner, several factors should be considered. It is generally worth repairing the unit if it's less than 10 years old, the warranty is still active, and you're dealing with a one-off issue. Most central AC units last about 15 years, while window units last 8 to 10 years. If your unit is approaching or has surpassed the 10-year mark and requires frequent or costly repairs (e.g., over $5,000), replacement is often the more sensible long-term investment. For older, inefficient, or out-of-warranty units experiencing multiple problems, replacing it is typically the better choice.

The American Society of Heating, Refrigerating, and Air-Conditioning Engineers, or ASHRAE, sets the standard guidelines for air changes per hour in homes and businesses. The International Residential Code, or IRC, also sets ACH requirements for residences and bases those requirements off of ASHRAE standards plus climate specifics related to your location.

AC evaporator coils should be cleaned at least once per year to keep your unit in good condition. For optimal performance, consider cleaning them twice a year—once before and once after the main cooling season. More frequent cleanings may be necessary for older systems, units with performance issues, or those in climates with high levels of humidity, dust, and dirt.

The best way to save money on HVAC repairs is by regularly having your system inspected and maintained. This can prevent bigger problems and costly repairs and replacements in the future. It’s also smart to buy quality equipment and hire companies that provide warranties on equipment and labor. If you need repairs, you may be able to save money by cashing in on rebates and incentives or keeping the area around your HVAC unit clear to shorten the time your contractor needs to spend in your home.
