This is possibly the most common question we are asked, and several factors can persuade the decision either way. Some of the things to consider are the age of the equipment, the repair history of the system, the reliability of the manufacturer and what refrigerant your system uses.

Answers: As your system approaches that 12 year mark be cautious about repairs especially if it has to do with adding refrigerant or leaks. If your system has been well maintained and does not have a history of adding refrigerant by all means, consider repairs less than $750. Some manufacturers have better track records than others, there are certain brands that make me roll my eyes when I walk up on them because I know the outcome.

The big one, if your system uses R-22 the old refrigerant and its leaking I won’t repair it, it is a liability to you and me. The current cost for a 30lb cylinder of R-22 is $700, don’t do it.

Our industry is going through constant efficiency changes due to the EPA and multi national agreements that address climate change. Every new benchmark that is agreed upon ends up costing you the customer money, there are new refrigerants being manufactured that are less harmful to the ozone that manufacturers must adopt their equipment to work with. In 2025 we will see two new refrigerants added to new equipment that have a lower GWP (Global Warming Potential) these will make the current refrigerant R-410 more expensive as phase out dates are enacted.

There are only about 8 mainstream manufacturers left, there may be thirty brand names, but those are just decals. I have had experience with every one of them, 22 years of repairing, getting tech support, filing warranties, dealing with defects, holding manufacturers accountable and holding home owners accountable.

Here is what you should look for: A very good, well trained responsive HVAC company, remember what I said there are only 8 manufacturers, yes equipment is important, I love both my AMANA brand and TRANE brands, but they each fill different needs for me and the consumer, Trane has a long history of dependable, innovative equipment and it has a reputation and a name that people want to pay for.

Many factors go into determining the size of the system. Including the type of house and walls, type and size of windows, insulation, basement and attic conditions, house orientation, and so on. A comfort consultant must visit the house and take detailed measurements. With these measurements, the comfort consultant can perform a performance load calculation in order to assure proper system size.

A system that is too large will cool or heat your house quickly, but you may not feel comfortable. That’s because it will satisfy the thermostat before it can adequately remove sufficient moisture from the air during the cooling mode, leaving you feeling sticky and humid. This could even lead to moisture and mold problems. And, the stress of short-cycling (too many starts and stops) will shorten the life of your equipment and increase your heating and cooling bills.

On the other hand, a system that is too small just cannot get the job done, especially in extreme weather conditions. The air conditioner will constantly run in the summer and the furnace will do the same in winter. But a correctly sized system isn’t just based on the size of the structure.

HVAC Tips For Your Home

Check your filter each month. A dirty filter starves your system of air and causes excessive wear on your air conditioner, furnace or heat pump. Replace your filter when necessary, or clean it if you have the reusable type. If you have a reusable filter, make sure it’s completely dry before you reinstall it.

Keep your outdoor condensing unit free of debris. If you keep grass clippings, leaves, shrubbery and debris away from your outdoor unit, it should only require minimal care. Check the base pan (under the unit) and remove debris to help the unit drain properly.

You can save as much as 10% a year on your heating and cooling bills by simply turning your thermostat back 10% to 15% for 8 hours per day. You can do this automatically, without sacrificing comfort, using a programmable thermostat.

With the programmable thermostat, you can pre-set it to call for less heat or air during the times when you won’t be at home. You can program a different schedule for each day of the week.

Be sure your home is adequately insulated. Adding insulation to attic areas is usually pretty straightforward. Other areas, such as outside walls, provide a more challenging project if extra insulation is needed.

Make sure your outdoor condensing unit stays in a level position. If the support for your outdoor unit shifts or settles, re-level it to make sure moisture drains properly out from under the unit.

Check the seals around windows, doors, electrical outlets or any other potential sources for escaping air. Seal these areas using a good quality caulk and be sure to re-examine your work every few years.
