"I really can't say enough good about Westin Air and the team of people who work there. Professional all the way. This was simply an annual system check-up on the TRANE HVAC system Westin Air installed late summer last year. Justin and Frank were the technicians. They neatly performed annual maintenance on the system and answered a few questions I had about the unit's staging system. These folks are PROS and I highly recommend them."

"We were very pleased with the service that we received from CARE! I contacted three different companies and they were the first to respond and their estimate was the cheapest. We were looking for a basic system and that is exactly what we got. We did not feel pressured to get anything more than we asked for and Andy was very helpful. Matt and Kirk, who installed our new system, were fast and efficient. We will definitely contact CARE again in the future for any HVAC needs."

"We had a great experience with Franklin Heating/Cooling and their employee Tony when they came to fix our AC. From start to finish, Tony was professional, efficient, and incredibly honest. It's not every day you come across a service company that doesn't try to upsell unnecessary repairs or replacements. They took the time to thoroughly assess the issue, explain what needed fixing, and offered a clear, fair solution. We really appreciated his transparency and how he genuinely prioritized our best interest over making a quick sale. It's rare to find companies that are this trustworthy, and I will definitely be using them for any future HVAC needs. Highly recommend!"

"Tyler replaced our 22 year old central air conditioner. From the initial call for a quote to the final installation the entire project was perfect. His years of experience were obvious as the job was professionally handled. He later serviced our gas furnace, explaining all of what was occurring while giving the furnace its best check ever. Delta-T is our "go-to" HVAC firm in the future."

Heating and Air Conditioning questions, answered by experts

The simplest indicator is how long it’s been since your last tune-up. You should schedule an annual AC tune-up each spring. Beyond that, there are multiple signs that your AC needs a quick check by a professional. These issues include higher-than-average energy bills, decreased air flow from vents, higher indoor temperatures, and an air conditioning unit that stays on all the time or frequently turns on and off.

It’s not customary to tip HVAC technicians, and most professionals won’t expect it. However, it’s a nice way of showing your appreciation for the work they do, especially if they come out in inclement weather or on a weekend or holiday to fix an emergency issue if your heat or AC goes out in extreme temperatures. A good tip would be between 10% to 20% of the total bill, depending on how above and beyond the tech goes for your repair and on the total cost of your HVAC repair or service. For something like a routine tune-up or scheduled maintenance, tips aren’t expected.

A one-stage air conditioner only has one setting, while a two-stage air conditioner has a high and low setting. A two-stage air conditioner costs between $500 and $2,500 more than a traditional air conditioner, but it has a longer lifespan and helps to increase energy efficiency. To make this decision, you should consider your energy needs and available budget.

The right type of HVAC system will depend on several factors, including your climate, budget, preferences, and existing HVAC setup. For example, if you live in an area that experiences extreme weather, then a split system would likely be the best option. Or, if budget is a concern, consider installing a ductless system in just one room.

If you have central air conditioning, it’s fine to run your AC all day if that’s what you want—as long as the AC unit is in good condition. But if your AC runs constantly when you don’t want it to, there may be a problem with your system (like the ones we’ve mentioned above). Window AC units and wall air conditioners aren’t as powerful as central AC, so you should only run those kinds of air conditioners for eight to 12 hours at a time.
